SRPP — Lactuca sativa

Summary

LsSRPP, encoded by the gene LSAT_V11C500259760 on chromosome 5 of garden lettuce (Lactuca sativa), is a member of the proline-rich protein family. The gene is associated with plant-type cell wall biogenesis, root hair cell development, polar cell growth, seed development, heat acclimation, response to ethylene, and cellular response to phosphate starvation. It localizes to the cell periphery and plant-type cell wall. Observed phenotypes linked to LsSRPP include root hair development and seed viability. Studies of related genes in other species connect the family to reduced root length, shorter root hairs, abnormal embryos, reduced germination, and thermotolerance, as well as traits including drought tolerance, germination rate, and seed growth and development.
