Auxin and Temperature Stress: Molecular and Cellular Perspectives
Temperature stress is one of the major abiotic stresses that limit plant growth and development and crop productivity worldwide. Plant growth and development is also influenced by endogenous factors such as hormones, and under environmentally stressed conditions. Plants adapt themselves through multiple processes, including a change in hormonal response. Recent evidence indicates that under optimal condition, the plant hormone auxin plays a key role in determining plant development processes through modulating other hormonal responses. However, little is known about the role of auxin under temperature stress. The emerging picture from recent experiments indicates that like under optimal condition, auxin also plays a crucial role in regulating plant growth under temperature stress. In this chapter, we tried to integrate our current understanding on the role of auxin in regulating plant developmental processes under temperature-stressed condition and the future direction of research that may help us in engineering plants/crops for sustainable agriculture.
