SHD — Pisum sativum

Summary

PsSHD (PSAT6G002360) on chromosome 6LG2 encodes an endoplasmin homolog belonging to the Hsp90 family, with ATP-dependent protein folding chaperone activity. The gene is associated with diverse biological processes including sterol anabolism, fatty acid beta-oxidation, telomere maintenance, protein maturation and secretion, and downregulation of DNA endoreduplication. It localizes to the endoplasmic reticulum lumen and perinuclear cytoplasm. PsSHD has been linked to agronomically important traits including drought tolerance, salt stress tolerance, seed viability, seed set percent, flowering time, pollen fertility, root development, and insect damage response. Studies of related genes in other species connect the family to thermotolerance, salt tolerance, endoplasmic reticulum function, telomere length regulation, and floral meristem development.
