LEA — Triticum aestivum

Summary

TRAESCS5D02G026500, designated TaLEA-5D, encodes a late embryogenesis abundant (LEA) protein containing a seed maturation protein (SMP) domain on bread wheat chromosome 5D. The gene is associated with a wide range of biological processes including cold acclimation, embryogenesis, seed development, stomatal closure, detoxification, immune response, ethene metabolism, and glutathione metabolism. TaLEA-5D has been linked to numerous agronomically important traits such as grain weight, grain size, grain protein content, seed dormancy, sprouting tolerance, plant height, anthesis time, heat tolerance, salinity tolerance, water use efficiency, photosynthetic rate, and leaf chlorophyll content. Additional associations include abscisic acid content and response, seed germination, seed maturation, osmotic adjustment capacity, and concentrations of zinc and iron. The gene also shows connections to plastid localization, cuticle anabolism, and virus-induced post-transcriptional gene silencing.
