Abstract

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.
