SRPP — Lactuca sativa

Summary

LsSRPP, encoded by gene LSAT_V11C500259790 on lettuce chromosome 5, is a member of the proline-rich protein family. In lettuce, the gene is associated with plant-type cell wall biogenesis, root hair cell development, polar cell growth, seed development, and responses to ethylene, low humidity, phosphate starvation, and heat acclimation. The encoded protein localizes to the cell periphery and plant-type cell wall. Annotated associations link LsSRPP to root hair development and seed viability. Studies of related genes in other species connect the family to drought tolerance, salt tolerance, thermotolerance, germination rate, and seed growth traits, as well as to reduced root length, shorter root hairs, abnormal embryos, and reduced germination.
