Low temperature sensors in plants: Hypotheses and assumptions

An overview of research seeking and studying the potential low temperature sensors in plants is provided. It was shown that the number of potential candidates for low temperature sensors is quite wide and includes both individual intracellular structures and substances: membranes, cytoskeletal elements, chromatin, phytochromes, DNA, RNA, specific proteins, and sugars. It was noted that, depending on the mode of thermal exposure (intensity, cooling rate, duration, etc.), the leading role of temperature sensors may be played by different structures or substances. Apparently, this variety allows plants to respond to cold more flexibly and appropriately.
