Effect of high-temperature, drought, and nutrient availability on morpho-physiological and molecular mechanisms of rapeseed - an overview

Production of high yielding cereals and oilseed crops is a major challenge for the farming community to meet the increasing global food demands. In many areas, global food production is challenged by abiotic and biotic factors which adversely hamper the growth of plants. Abiotic stresses, for instance, water, temperature, and essential soil nutrients stress affect the plant's growth. Plants have a different mechanism, which enables them to complete their life cycle under stress conditions, for example, some plants use environmental signals to regulate their morpho-physiological and molecular mechanisms. There is a huge gap of knowledge to identify the genetic mechanisms to mitigate the abiotic stresses. Given the current state of understanding; we have consciously focused on the effect of multiple abiotic stress-signals on morphophysiological and molecular mechanisms of Brassica napus. Further, this review emphasizes the link between different abiotic stresses (high temperature, drought, and low nutrients availability) which ultimately regulate the growth and development of Brassica napus.
