LEA — Pisum sativum

Summary

PSAT5G005440 (PsLEA, also known as PsDHN1) encodes a dehydrin family protein containing the Dehydrin_CS domain and is associated with metal binding. In garden pea, this gene is linked to seed maturation, cold acclimation, cellular responses to salt, desiccation, drought, and light stimulus, as well as hormone metabolism, calcium signaling, detoxification, and protein synthesis. It has been connected to seed longevity and photosynthetic rate, and to seedling establishment. The protein localises to the cytosol, cytoplasm, and nucleus. Studies of related genes in other species link the family to drought tolerance, seedling vigor, cell membrane stability, water use efficiency, germination rate, seed size, plant height, root length, chlorophyll content, and various stress responses, though these associations are not yet established in pea.
