Abstract excerpt

Seed longevity (SL) is vital for ensuring food security worldwide. However, the genetic basis of SL has been scarcely documented. Here, we report the cloning of a major SL locus, qSL6, encoding a fatty acyl-ACP thioesterase type B. SL6 is functionally conserved in regulating palmitic acid synthesis in seeds, conferring higher oxidation durability and SL in various species. Through the VP1-SL6 module, a seed...
