ltp — Triticum aestivum

Summary

TRAESCS7A02G565488 (symbol ltp, also known as TaLTP3 or LTP2-B) on bread wheat chromosome 7A encodes a bifunctional inhibitor/plant lipid transfer protein/seed storage helical domain-containing protein belonging to the plant non-specific lipid transfer protein (nsLTP) family. The gene product is annotated for lipid binding and lipid transport, and is associated with phosphatidic acid anabolism and broader lipid metabolism. In wheat, LTP3 has been associated with salt tolerance, deoxynivalenol accumulation, and leaf rust resistance. The gene is also associated with responses to powdery mildew, high temperature stress, oxidative stress, and drought tolerance. Studies of related genes in other species link the family to deoxynivalenol content in Fusarium, rice leaf blast disease response, and oxidative stress and heat stress tolerance in Arabidopsis.
