PCS1 — Triticum aestivum

Summary

TRAESCS3D02G355300 (TaPCS1) on wheat chromosome 3D encodes an aspartic peptidase A1 family protein with protease and aspartic endopeptidase activity. The gene is associated with very-long-chain fatty acid metabolism, cuticle and wax anabolism, xyloglucan metabolism, cell wall organization, defence response to Gram-negative bacteria, regulation of programmed cell death, sexual reproduction, and cellular response to auxin stimulus. It localizes to the apoplast, ER, and extracellular space. TaPCS1 is associated with reproductive period, cadmium concentration, panicle length, grains per spike, cold tolerance, and floral organ identity. Phenotypic associations include arsenate and cadmium tolerance, embryo development, male sterility, and embryonic lethality. Studies of related genes in other species connect the family to disease resistance, metal homeostasis, and salt tolerance.
