LEA3 — Sorghum bicolor

Summary

SORBI_3009G215700, designated SbLEA3 on sorghum chromosome 9, encodes a late embryogenesis abundant (LEA) protein belonging to the LEA1/2/D7/KIN2 family. The gene product is annotated with L-lactate dehydrogenase (cytochrome) activity and localises to both the cytosol and nucleus. SbLEA3 is associated with protein stabilization, response to freezing, embryogenesis, and responses to thirst and NO storage. It has been linked to drought tolerance, salinity tolerance, heat tolerance, drought response, and seed texture. Related genes in other species are associated with desiccation tolerance and freezing tolerance. The family is also associated with traits including cold tolerance, seed maturation, germination rate, chlorophyll content, abscisic acid content, ferulic acid content, flavonoid content, anthesis time, and root morphology.
