Thermotolerance is a biological process by which cells, tissues, or organisms acquire the capacity to survive and maintain function under elevated temperatures that would otherwise be lethal or damaging. It involves coordinated molecular responses including induction of heat shock proteins and molecular chaperones, stabilization of protein structure, remodeling of membranes, modulation of reactive oxygen species detoxification systems, and activation of protective signaling pathways such as heat shock factor (HSF)-mediated transcription. Thermotolerance can be constitutive or inducible, often developing after a mild heat pretreatment, and contributes to cellular homeostasis, proteostasis, and integrity of critical processes such as DNA replication, transcription, translation, and photosynthesis under thermal stress.
How do you cool yourself on a hot day? Perhaps you find shade, switch on a fan or retreat to air conditioning? But spare a thought for tropical forest trees. As the climate warms, they must either adjust to the heat, adapt ...
