Deciphering the melatonin-mediated response and signalling in the regulation of heavy metal stress in plants.

Melatonin has a protective effect against heavy metal stress in plants by immobilizing HM in cell walls and sequestering them in root cell vacuoles, reducing HM's translocation from roots to shoots. It enhances osmolyte production, increases antioxidant enzyme activity, and improves photosynthesis, thereby improving cellular functions. Understanding the melatonin-mediated response and signalling can sustain crop production in heavy metal-stressed soils.

Enhancing biocontrol potential of against borer pests of wheat and chickpea.

Communication between plants and herbivores occur mostly through chemicals. Plants emit volatiles in response to the attack of herbivores called herbivore-induced plant volatiles (HIPVs), which are employed by the plants to attract their herbivores' natural enemies. Promising HIPVs when used in the form of controlled release formulations under field conditions can act as arrestants of released or wild population of parasitoids to spend comparatively more time in searching of various stages of herbivores; thus management of crop pests is enhanced.
