Ozone, the gas best-known for protecting us from the ultraviolet rays of the sun, can turn harmful if produced in excess quantities by human activities. A team of researchers from the Banaras Hindu University have studied the effect of elevated ozone on plants that inhabit the lush grasslands of central India.
Just like animals, plants often face threats from their environment, including attacks by parasites, pests, and grazing animals. Unlike animals, however, plants cannot simply move away from the source of such threats. A new study from researchers at NIPGR, New Delhi, offers insights into the intricacies of the plant defence system and how it recognizes and responds to danger, particularly from insect pests.
Researchers from the University of Mysore have recently found that an enzyme extracted from the leaves of a medicinal plant, Tricosanthus tricuspidata, can counter the tissue damage caused by the bite of the venomous saw-scaled viper. This is the first scientific report of the anti-snake venom properties of this plant, which is known to be used by local tribal communities to treat snakebites.
For plants, choosing to fight against a pathogen often comes at the cost of compromised growth and development. Now, scientists from Jawaharlal Nehru University (JNU), Delhi and the Indian Institute of Science, Education & Research, Thiruvananthapuram (IISER-TVM) find a new molecular player that helps maintain this delicate balance.
Scientists develop DNA barcodes to distinguish between and accurately identify over three hundred varieties of Thrips.
