Improving Stress Resilience in Plants: Physiological and Biochemical Basis and Utilization in Breeding, Mohammad Abass Ahanger,Javaid Akthar Bhat,Parvaiz Ahmad,Riffat John, Editör, Academic Press , Massachusetts, ss.277-295, 2024
Because of their immobile nature, plants are often exposed to various
biotic and abiotic stress factors that limit their productivity. In
recent years, temperatures have risen steadily because of global warming
and climate change. Heat stress is an important environmental stressor
that severely affects the growth and development of plants. It is
therefore essential to understand the process of responding to heat and
to increase heat tolerance in plants. To address these difficult
environmental conditions, plants have developed coping mechanisms that
help them survive and respond to these situations. The synthesis of heat
shock proteins (HSP) is one of the strategies that help plants tolerate
elevated temperatures. HSPs, as chaperones, involve in conferring
stress tolerance by protecting plant protein structure and conformation.
Phytohormones are endogenous signal molecules and play important roles
in coordinating processes related to plant growth and development. They
also involve helping plants adapt to environmental stresses. Auxines,
gibberellins, cytokinins, abscisic acid, ethylene, salicylic acid,
jasmonates, brassinosteroids, and strigolactones are the main hormones
produced by plants. To shed light on the mechanisms regulating tolerance
to thermal stress, it is essential to understand the relationship
between HSP and phytohormones and their role in responding to plant
stress. Thus, in this chapter, we discuss the roles of plant hormones in
response to heat stress through the regulation of HSPs.
