LEA (TRAESCS5A02G021400) — triticum aestivum

Summary

TRAESCS5A02G021400, designated TaLEA-5A, encodes a late embryogenesis abundant (LEA) protein containing an LEA_SMP domain on bread wheat chromosome 5A. The gene is associated with seed maturation, embryogenesis, and seed development, as well as cold acclimation, stomatal closure, detoxification, and immune memory response. It has been linked to ethene metabolism, glutathione metabolism, cuticle anabolism, and the pentose-phosphate shunt. TaLEA-5A is associated with sprouting tolerance, grain weight, grain protein content, seed color, plant height, days to flowering, heat and salinity tolerance, water use efficiency, photosynthetic rate, and chlorophyll content. It is also associated with seed germination, seed dormancy, and abscisic acid response. Studies of related LEA family members in other species link the family to cold tolerance, germination rate, root length, and leaf size.
