Question

How may a plant respond to severe heat stress? how may a plant respond to severe heat stress? by producing heat-shock proteins, which may protect the plant's proteins from denaturing by reorienting leaves to increase evaporative cooling by creating air tubes for ventilation by initiating a systemic acquired resistance response by increasing the proportion of unsaturated fatty acids in cell membranes, reducing their fluidity?

Answer 1

The plant responds to severe heat stress by producing heat-shock proteins, which may protect the plant's proteins from denaturing. These heat-shock proteins or chaperones are responsible for protein folding, assembly, degradation and also translocation in many cellular processes. Additionally, they stabilize proteins and membranes and can also assist in refolding of proteins under stress conditions.
