• Calcium ions and immune protein ring disaster bells in plants

  

  Researchers from National Institute of Plant Genome Research (NIPGR) have uncovered how plant cells attacked by insects communicate distress to other cells of the plant. In the first 5-10 minutes after the attack, a spike in calcium levels and the plant immune protein Plant Elicitor Peptide Receptor (PEPR) amplifies the damage signal, as plants brace for insect attack. The findings of this study can pave the way for protecting crops from pests.

• Insects in a warming world

  

  Climate change, propelled by human activities, presents a substantial threat to insect populations worldwide, impacting their behavior, fitness, and distribution. Subhash Rajpurohit and his research group at Ahmedabad University, Gujarat, emphasises the vulnerability of ectothermic insects to fluctuating temperatures and humidity levels. His lab's work offers insights into the intricate relationship between environmental stress, dehydration, and insect reproductive success within the context of climate change.

• A fern protein kills whiteflies by degrading chitin

  

  A team of researchers at the CSIR-National Botanical Research Institute (CSIR-NBRI), Lucknow, has investigated the functional activity of the plant protein Tma12, which is toxic to whiteflies. The study demonstrates that Tma12 kills whiteflies by degrading chitin. The findings of this research can be utilised by biorefineries in the production of biofuels and for expanding the horizons of biopesticides.

• Study finds gene transfer from early microbes might have helped the evolution of land plants

  

  Streptophyte algae are considered the ancestors of land plants who shared habitats with primitive microbes. However, scientists have been intrigued by how the algae developed mechanisms to evolve as land plants and survive the soil conditions below the ground. In this exciting study, a team of researchers reveal the crucial role primitive microbes could have played in the evolutionary process of land plants.

• Shall we grow in the dark? A COP1 story

  

  Plants react to their immediate environment in a number of ways and use the information so gleaned to make crucial decisions about growth and survival. In a new study, researchers from the Indian Institute of Science Education and Research (IISER) Bhopal have discovered a new molecular mechanism via which seedlings react to the absence of light and use it to modulate their growth rate to ensure optimum conditions for survival.

• The Pink Solution: “N-riching” rice plants

  

  A new collaborative study by researchers at University of Calcutta and University of Kalyani has found that a close symbiotic relationship between three species - a plant, a fungus, and bacteria - can be harnessed to promote the growth of rice plants by allowing them to take up more nitrogen from the environment.

• Which plant will dominate the grasslands of central India in 2050?

  

  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.
