  • Researchers found gene regulating Nitrogen absorption in Plant

    Researchers led by those from the National Centre of Biological Sciences, Tata Institute of Fundamental Research, Bengaluru (NCBS-TIFR), have found a new pathway that regulates nitrate absorption in plants.

    Nitrogen in plant nutrition

    • Nitrogen is one of the most important macronutrients needed for development of a plant.
    • It is a part of chlorophyll, amino acids and nucleic acids, among others.
    • It is mostly sourced from the soil where it is mainly absorbed in the form of nitrates and ammonium by the roots.
    • Nitrates also play a role in controlling genome-wide gene expression that in turn regulates root system architecture, flowering time, leaf development, etc.
    • Thus, while a lot of action takes place in the roots to absorb and convert nitrogen into useful nitrates, the absorbed nitrates in turn regulate plant development apart from being useful as a macronutrient.

    What is MADS27?

    • The gene MADS27, which regulates nitrate absorption, root development and stress tolerance, is activated by the micro-RNA, miR444, therefore offers a way to control these properties of the plant.
    • The researchers studied this mechanism in both rice (monocot) and tobacco (dicot) plants.

    Regulatory switches

    • In addition to this route, several gene regulatory switches that regulate nitrate absorption and root development, such as the micro-RNA, miR444, are known in monocot plants, such as rice.
    • The micro-RNA ‘miR444’ is specific to monocots.
    • When this is not made, its target, MADS27, is produced in higher abundance, and it improves biosynthesis and transport of the hormone auxin, which is key for root development and its branching.
    • This regulatory miR444 switch is known to turn off at least five genes called MADS box transcription factor genes.
    • The speciality of the MADS box transcription factors is that they function like switch boxes of their own.
    • They bind to their favourite specific DNA sequences and they switch the neighbouring genes “on.”

    Why is the discovery important?

    • Presence of nitrates is important for the plant development and also for grain production.
    • However, the overuse of nitrates in fertilizers, for instance, can lead to the dumping of nitrates in the soil which leads to accumulation of nitrates in water and soil.
    • This accumulation adds to soil and water pollution and increased contribution to greenhouse gases.
    • Also, since the whole process of nitrate absorption takes place in the roots, a well-developed root system is needed for this to take place optimally.
    • At one level, it is known that the hormone auxin is responsible for well-developed roots across all plants.
    • A number of genes are known to help with auxin production, improved nitrate transport and assimilation in plants.

    Significance of MADS27

    • The MADS27 transcription factor has a three-pronged effect on the plant.
    • First, it regulates nitrate absorption by switching “on” proteins involved in this process.
    • Second, it leads to better development of the roots by regulating auxin hormone production and transport.
    • Finally, and somewhat surprisingly to the researchers, it helps in the abiotic stress tolerance by keeping the main stress player proteins “on.”

  • Mayurbhanj’s superfood ‘Ant Chutney’

    The Kai Chutney made from Red Ants by the tribals of Mayurbhanj district in Odisha are seeking a Geographical Indications (GI) tag.

    Ant Chutney

    • Despite this, weaver ants are popular among the people, mostly of the tribes,
    • This food item, rich in proteins, calcium, zinc, vitamin B-12, iron, magnesium, potassium, sodium, copper, fibre and 18 amino acids, is known to boost the immune system and keep diseases at bay.
    • Applied under food category, the GI tag will help develop a structured hygiene protocol in the preparation of Kai chutney for standard wider use.
    • Geographical Indications labels enhance the reputation and value of local products and support local businesses.

    How is the Chutney prepared?

    • Weaver ants, Oecophylla smaragdina, are abundantly found in Mayurbhanj throughout the year.
    • They make nests with leaves of host trees.
    • The chutney is prepared by mixing and grinding salt, ginger, garlic and chilly and is sold by tribal people in rural markets.

    Back2Basics:  Geographical Indication

    • A GI is a sign used on products that have a specific geographical origin and possess qualities or a reputation that are due to that origin.
    • Nodal Agency: Department for Promotion of Industry and Internal Trade (DPIIT), Ministry of Commerce and Industry
    • India, as a member of the World Trade Organization (WTO), enacted the Geographical Indications of Goods (Registration and Protection) Act, 1999 w.e.f. September 2003.
    • GIs have been defined under Article 22 (1) of the WTO Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) Agreement.
    • GI is granted for a term of 10 years in India. As of today, more than 300 GI tags has been allocated so far in India (*Wikipedia).
    • The tag stands valid for 10 years.

  • Abhijit Ray, AIR 50, UPSC 2021

    “We must never forget the lonely non-glamorous long hard work behind success”. It’s not a success story of ‘Proving’. It’s a story of ‘Improving’.

    Hi Guys, Abhijit Ray secured AIR 50 in UPSC-CSE 2021. Let’s have a glimpse of his journey.


    Table of Content


    1. About Abhijit- His UPSC journey + Hobbies

    NameAbhijit Ray
    UPSC2021
    RankAIR 50
    No. of Attempts4
    Attempt in 2018couldn’t clear Prelims
    2019failed prelims again
    2020couldn’t clear Mains
    2021 AIR-50. Get in Final Merit list.
    Optional SubjectAnthropology (in all the attempts)
    HobbyComposing Poem & recreational cycling

    “Never overestimate yourself and don’t think that even a non-serious effort will take you through”.

    Went to several villages in Karnataka as a volunteer. That is the turning point in Abhijit’s life. He decided to work for them after seeing the pictures of the village. The answer came to mind — Civil Service.

     Abhijit Roy was an engineer by profession. After passing, he got a job in a first-class company in Bangalore. From the very beginning of his career, he was associated with the soil. He went to several villages in Karnataka as a volunteer for the CSR activities of the organisation he worked for. That is the turning point in life.

    But how? Going to inform you that, Abhijit mentioned an incident. He said, ‘I once went to a blind school in Karnataka. I saw that there is no basic facility. But not that it is very difficult to give. It will be done if you see a little. ‘ He had several such experiences.


    2. Family and education

    FatherMukul Charan Roy, a retired health official in Darjeeling
    Mother Dr. Chandra Roy, a homeopathic practitioner.
    Educationa) Completed schooling from St. Joseph’s School
    b) Completed Graduate Engineering from University in Delhi.

    His father and mother gave him their full support through all thick and thins. Although they were dubious about his leaving job for UPSC preparation initially, they stood beside him later on.


    3. UPSC Preparation Strategy

    Earlier failures taught Abhijit many priceless lessons. He shared his hard-earned experience separately for Prelims and Mains.

    Preparation Strategy for UPSC Prelims:

    • Practice, Practice and Practice. Abhijit couldn’t clear prelims in first 2 attempts because his practice was not sufficient.
    • PYQs: It is always helpful to have a good idea of the core areas of the question topics from the previous years papers.
    • Practicing Mock tests: UPSC prelims is a game of intelligent guessing rather than bookish knowledge. So, never ignore test series. Because test series can only help you to mend your mistakes.
    • Time & energy mustn’t be wasted on digesting more than 1 newspaper.
    • Revision & Consolidation: Revision is extremely important for all stages of the exam. Consolidating your studies is probably more important than reading new sources.
    • It’s better to talk with a senior IAS mentor, if you’re novice.

    Preparation Strategy for UPSC Mains:

    • Guidance: Do proceed your journey under the guidance of mentors at least in initial days.
    • Mains Prep: must be carried simultaneously with prelims. Answer writing practice is that skill that resolves everything.
    • Studying a lot new mains stuff after prelims must be avoided. Focus only on revision and improving answers quality.
    • Essay & Optional papers: These papers are game changing. In GS papers almost every candidate scores the same. So, the decider of your ALL INDIA RANK is them.
    • UPSC Main is the higher bar to cross so, selecting right sources, evaluation of answers, and hand-holding support are the key to success.

    4. Abhijit’s Notes + Booklist


    5. Motivation and Inspiration

    Abhijit is used to be a self-motivated person. Once he went to a blind school in Karnataka. The difficulty and hardship of the natives moved him deeply. It was his inspiration that he wanted to do something for their betterment.

    Besides his parents, he didn’t forget to mention about his office manager. He also inspired Abhijit time to time. Abhijit received influx of congrats after getting into final merit list 2021. He cordially thanked to his teachers & mentors.

  • How the RBI unconventionally innovated policy to fight the pandemic

    Context

    Recently, the RBI has been at the receiving end for mission the inflation target.

    Understanding the RBI’s rationale

    • Supply side shock: Inflation has been largely the result of supply side shocks from vegetable prices, caused by crop damages due to unseasonal rains (tomato, onion and potato) in late 2019 and widespread supply-side disruptions after the outbreak of the pandemic.
    • A narrow-minded focus on inflation caused by supply shocks would have constrained the MPC from supporting growth amidst the unprecedented loss of life and livelihood.
    • Focusing on recovery: Therefore, it was necessary to provide a lifeline to the economy at that juncture by focusing on the recovery.
    • Moreover, the wide tolerance band of 200bps +/- in the inflation targeting framework was specifically designed to accommodate such supply shocks, which provided the flexibility in the flexible targeting (FIT) framework.
    • Taking into account objective of growth: In contrast to a pure inflation targeting framework (inflation nutters), the amended mandate of the RBI under FIT reads as “price stability, taking into account the objective of growth”.
    • Therefore, the MPC was justified in looking through the higher inflation print during the pandemic while trying to resurrect growth.

    No contradiction between Governor’s statement and MPC resolution

    • Recently, the MPC highlighted inflation concerns and voted to raise the policy repo rate.
    • The governor’s statement of the same day noted that the RBI will ensure an orderly completion of the government’s borrowing programme.
    • Contradictory objectives: It is said that the above two actions created confusion as lowering inflation and lowering government bond yields are contradictory objectives.
    • This justification is redundant as an orderly completion of the borrowing programme does not imply lowering yields.
    • It basically ensures that the borrowing programme is completed seamlessly at low costs (ensured through auctions).
    • Moreover, from a theoretical perspective, this is not inconsistent because controlling inflation and lowering inflation expectations bodes well for the term premia of bond yields — which moderate once expectations are anchored.
    • Therefore, if inflation is reined in, the government stands to gain in terms of lower interest costs.
    • Was width of corridor lost during pandemic? It is argued that  the MPC kept repo rates unchanged while the RBI changed the reverse repo rate during the pandemic, meaning that the fixed width of the corridor was lost and the MPC lost its role in setting interest rates and so, its credibility.
    • This argument does not stand scrutiny.
    • During the pandemic, the policy repo rate was cumulatively reduced by an unprecedented 115 bps and the interest rate on the overnight fixed-rate reverse repo was reduced cumulatively by 155 bps.
    • Assymetric corridor justified in crises: This measure was not incongruous with contemporary wisdom as an asymmetric corridor has been justified, particularly during crisis times (Goodhart, 2010).
    • Given that elevated inflation concerns precluded the possibility of any further repo rate cuts (cumulatively reduced by 250 basis points since February 2019), financial conditions were eased substantially by reducing the reverse repo rate, which lowered the floor rate of interest in the economy.
    • Since the mandate of the MPC is to control inflation for which the policy instrument is the repo rate, the RBI had used the LAF through changes in the reverse repo rate to alter liquidity conditions.

    Trade offs involved in inflation targeting for emerging economies

    • Inflation-targeting countries, because of their sole focus on inflation, experience lower inflation volatility but higher output volatility.
    • Higher output volatility entails a higher sacrifice ratio — the proportion of output foregone for lowering inflation.
    • For an emerging economy, the costs of higher output foregone against the benefits of lower inflation must always be balanced as potential output keeps on changing given the shift of the production function.
    • Developed countries, on the other hand, operate near full employment — therefore, sacrifice ratios are lower.
    • As a result, smoothening inflation volatility is relatively costless for them.

    Conclusion

    The RBI has innovated admirably under its current stewards during the pandemic, keeping in mind the task of reinvigorating the economy. Despite the existing targeting framework, it did not get fixated on a one-point agenda, daring to look beyond the inflation print.

    Back2Basics: Liquidity corridor

    • The Corridor in monetary policy of the RBI refers to the area between the reverse repo rate and the MSF rate.
    • Reverse repo rate will be the lowest of the policy rates whereas Marginal Standing Facility is something like an upper ceiling with a higher rate than the repo rate.
    • The MSF rate and reverse repo rate determine the corridor for the daily movement in the weighted average call money rate.

  • What are G-Sec Yields?

    Government Securities (G-Secs) yields are at an all-time high.

    What are G-Secs?

    • These are debt instruments issued by the government to borrow money.
    • The two key categories are:
    1. Treasury bills (T-Bills) – short-term instruments which mature in 91 days, 182 days, or 364 days, and
    2. Dated securities – long-term instruments, which mature anywhere between 5 years and 40 years

    Note: T-Bills are issued only by the central government, and the interest on them is determined by market forces.

    Why G-Secs?

    • Like bank fixed deposits, g-secs are not tax-free.
    • They are generally considered the safest form of investment because they are backed by the government. So, the risk of default is almost nil.
    • However, they are not completely risk-free, since they are subject to fluctuations in interest rates.
    • Bank fixed deposits, on the other hand, are guaranteed only to the extent of Rs 5 lakh by the Deposit Insurance and Credit Guarantee Corporation (DICGC).

    How are G-sec yields calculated?

    • G-sec yields change over time; often several times during a single day.
    • This happens because of the manner in which G-secs are structured.
    • Every G-sec has a face value, a coupon payment and price.
    • The price of the bond may or may not be equal to the face value of the bond.
    • Here’s an example: Suppose the government floats a 10-year G-sec with a face value of Rs 100 and a coupon payment of Rs 5.
    • If one were to buy this single G-sec from the government, it would mean that one will give Rs 100 to the government today and the government will promises to 1) return the sum of Rs 100 at the end of tenure (10 years), and 2) pay Rs 5 each year until the end of this tenure.
    • At this point, the face value of this G-sec is equal to its price, and its yield (or the effective interest rate) is 5%.

    How do G-sec yields go up and down?

    • Imagine a scenario in which the government floats just one G-sec, and two people want to buy it.
    • Competitive bidding will ensue, and the price of the bond may rise from Rs 100 (its face value) to Rs 105.
    • Now imagine another lender in the picture, which pushes the price further up to Rs 110.

    What do G-sec yields show?

    • If G-sec yields (say for a 10-year bond) are going up, it would imply that lenders are demanding even more from private sector firms or individuals; that’s because anyone else is riskier when compared to the government.
    • It is also known that when it comes to lending, interest rates rise with the rise in risk profile.
    • As such, if G-sec yields start going up, it means lending to the government is becoming riskier.
    • If you read that the G-sec yields are going up, it suggests that the bond prices are falling. But the prices are falling because fewer people want to lend to the government.
    • And that in turn happens when people are worried about the government’s finances (or its ability to pay back).
    • The government’s finances may be in trouble because the economy is faltering and it is unlikely that the government will meet its expenses.
    • By the reverse logic, if a government’s finances are sorted, more and more people want to lend money to such a G-sec.
    • This in turn, leads to bond prices going up and yields coming down.

  • GST revenues surpass ₹1.44 lakh crore

    India recorded its second-highest monthly gross GST revenues in June at ₹1,44,616 crore, 56% more than a year earlier when the second COVID wave had hit economic activity.

    What is GST?

    • GST is an indirect tax that has replaced many indirect taxes in India such as excise duty, VAT, services tax, etc.
    • The Goods and Service Tax Act was passed in Parliament on 29th March 2017 and came into effect on 1st July 2017. It is a single domestic indirect tax law for the entire country.
    • It is a comprehensive, multi-stage, destination-based tax that is levied on every value addition.
    • Under the GST regime, the tax is levied at every point of sale. In the case of intra-state sales, Central GST and State GST are charged. All the inter-state sales are chargeable to the Integrated GST.

    Answer this PYQ in the comment box:

    Q.All revenues received by the Union. Government by way of taxes and other receipts for the conduct of Government business are credited to the (CSP 2015):

    (a) Contingency Fund of India

    (b) Public Account

    (c) Consolidated Fund of India

    (d) Deposits and Advances Fund

     

    [wpdiscuz-feedback id=”jkgx8spg2w” question=”Please leave a feedback on this” opened=”1″]Post your answers here.[/wpdiscuz-feedback]

    What are the components of GST?

    There are three taxes applicable under this system:

    1. CGST: It is the tax collected by the Central Government on an intra-state sale (e.g., a transaction happening within Maharashtra)
    2. SGST: It is the tax collected by the state government on an intra-state sale (e.g., a transaction happening within Maharashtra)
    3. IGST: It is a tax collected by the Central Government for an inter-state sale (e.g., Maharashtra to Tamil Nadu)

    Advantages Of GST

    • GST has mainly removed the cascading effect on the sale of goods and services.
    • Removal of the cascading effect has impacted the cost of goods.
    • Since the GST regime eliminates the tax on tax, the cost of goods decreases.
    • Also, GST is mainly technologically driven.
    • All the activities like registration, return filing, application for refund and response to notice needs to be done online on the GST portal, which accelerates the processes.

    Issues with GST

    • High operational cost
    • GST has given rise to complexity for many business owners across the nation.
    • GST has received criticism for being called a ‘Disability Tax’ as it now taxes articles such as braille paper, wheelchairs, hearing aid etc.
    • Petrol is not under GST, which goes against the ideals of the unification of commodities.

    Take a look at the share of GST in government earnings for the previous fiscal:

    UPSC can ask about the majority component of the Revenue Receipts of the govt. See how Corporate tax is nearing the GST revenues.

    Do you think it will surpass GST revenue when the economy is fully recovered?
