E) LEA proteins

Question

Quizplus · Accepted Answer

LEA (Late Embryogenesis Abundant) proteins are known to be upregulated in response to various environmental stresses, including drought and cold-hardening. These proteins help to stabilize membranes and prevent protein aggregation, thus protecting cells from damage caused by stress. Tannins, nicotine, jasmonate, and canavanine are not typically associated with drought or cold stress responses in plants.
