 RNA-based antiviral for Plant Virus

Prelims (GS I) - General Science| Current events of national and international importance.

Mains (GS III) – Science and Technology- developments and their applications and effects in everyday life.

Why in news?

Researchers recently reported developing an RNA-based antiviral agent that confers strong protection against cucumber mosaic virus (CMV).

  • Plant virus – It is a microscopic, infectious agent that causes diseases in plants.
  • It destroys a significant portion of annual crops worldwide.
  • Unlike bacteria or fungi, viruses cannot be controlled with pesticides or fungicides.
  • Cucumber Mosaic Virus (CMV)
  • CMV is a plant virus that infects more than 1,200 plant species, including critical food crops like cucumbers, squash, and cereals, and medicinal plants.
  • Spread through - sap-sucking insects called aphids.
  • Effects - Infected plants develop mosaic discoloration, stunted growth, and commercially unviable fruits.
  • Severity - Nearly 90 aphid species are capable of transmitting CMV, making outbreaks difficult to contain.

In India, CMV causes 25-30% yield losses in banana plantations.

Current RNA-based Crop Protection Techniques

  • RNA Silencing – It is a natural defense mechanism in plants.
  • When a virus infects a plant, it introduces double-stranded RNA (dsRNA).
  • The plant responds by activating Dicer-like enzymes (DCLs), which slice the dsRNA into small fragments called small interfering RNAs (siRNAs).
  • These siRNAs guide the plant's defense system to recognize and destroy viral RNA.
    • Limitations – Not all siRNAs are effective, and some plant viruses can mutate rapidly.
  • Host-induced gene silencing (HIGS) – It works by genetically modifying plants to produce virus-fighting dsRNA in their cells.
    • Limitations - High production costs.
  • Spray-induced gene silencing (SIGS) - More flexible alternative to HIGS where plants are treated with RNA sprays instead of being genetically modified.
    • Limitations - Traditional dsRNA Spray formulations produce a random mix of siRNAs, and many are ineffective.

Key Findings of the Research

  • Researchers first screened and identified the most potent siRNAs against CMV.
  • These specially selected siRNA bind to the virus’s genetic material to trigger a stronger antiviral response.
  • Then they designed effective dsRNA (e-siRNAs) enriched with highly functional siRNA.
  • These e-siRNAs were assembled into dsRNA constructs for more targeted protection.
  • CMV infected plants treated with the enhanced siRNA had almost 80% lower viral load.
  • The new dsRNA formulation outperformed traditional dsRNA and it is effective against multiple CMV strains.

Advantages of the New Approach

  • More precise targeting of viral particles of the most vulnerable genetic regions.
  • Stronger defense by targeting multiple regions of viral genome simultaneously.
  • The effective dsRNA can be redesigned in about a month to target new viral strains.

Indian Cybercrime Coordination Centre (I4C)

Prelims – Current events of national and international importance.

Mains (GS III) – Basics of cyber security, money-laundering and its prevention.

Why in news?

Recently, Union Ministry of Finance issued notification to include Indian Cyber Crime Coordination Centre (I4C) under the Section 66 of the Prevention of Money Laundering Act (PMLA).

  • Indian Cyber Crime Coordination Centre (I4C) acts as a nodal point to curb cybercrime in the country.
  • Established on – 2020.
  • Nodal ministry – Ministry of Home Affairs.
  • Aim – To provide a framework and eco-system for Law Enforcement Agencies (LEAs) for dealing with Cybercrime in a coordinated and comprehensive manner.
  • Functions – It works to strengthen efforts against cybercrimes committed against women and children.
  • It facilitates easy filing of cybercrime-related complaints and helps identify cybercrime trends and patterns.
  • It also acts as an early warning system for law enforcement agencies to enable proactive cybercrime prevention and detection.
  • It promotes public awareness about preventing cybercrimes.
  • It assists States/UTs in building the capacity of police officers, public prosecutors, and judicial officers related to cyber-crime.
  • States/UTs are primarily responsible for the prevention, detection, investigation, and prosecution of crimes, including cybercrime and digital arrest scams, through their law enforcement agencies (LEAs)

Cybercrimes fall in State subjects as per the 7th Schedule of the Constitution of India.

  • Data Sharing by Enforcement Directorate (ED) The Finance Ministry has included the I4C in the list of agencies with which the Enforcement Directorate is permitted to share information under the Prevention of Money Laundering Act (PMLA).
  • Reason – The measure comes amid growing instances of cyber frauds, Digital arrest and most cyber frauds are trans-national in nature.
  • I4C will be the 27th entity authorized for getting data from ED under Section 66 of Prevention of Money Laundering Act (PMLA), 2002.

Section 66 of PMLA empowers the head of the ED to share information to initiate action aginst violation of various laws.

  • Other entities authorized for such data sharing include SEBI, RBI, CCI, SFIO, GST Council and others.
  • Significance – The data from the Enforcement Directorate and other law enforcement agencies could help I4C to strengthen the country’s fight against cyber-enabled financial crimes.

The ‘Citizen Financial Cyber Fraud Reporting and Management System’, under I4C, launched in 2021 to enable immediate reporting of financial frauds and prevent the siphoning off of funds by fraudsters.
