Abstract Macrophomina phaseolina is a destructive soil-borne necrotrophic fungal pathogen that causes substantial yield losses in a wide range of economically important crops worldwide. Disease severity is strongly enhanced under drought, high temperature, and salinity stress, co...

Biochemical defence of plants: redox molecules and their role in the alleviation of heavy metal stress

Abstract Heavy metal contamination poses a major constraint to plant growth and agricultural productivity by disrupting cellular metabolism and inducing oxidative stress. Exposure to toxic metals results in excessive accumulation of reactive oxygen species (ROS), which damage bio...
