Lhcb4 — Pisum sativum

Summary

PSAT7G245920 (symbol Lhcb4, preferred name PsLHCB4.1) encodes a chlorophyll a-b binding protein of the light-harvesting complex family, localised to the thylakoid membrane of photosystems I and II. The gene is associated with chlorophyll binding, photosynthesis and light harvesting, the xanthophyll cycle, photoprotection, and chlorophyll fluorescence. It has been linked to leaf vascular tissue pattern formation and phloem transport, as well as auxin and brassinosteroid signalling, sumoylation, and responses to light stimulus. Associations with flowering time, leaf vein morphology, abnormal leaf venation, premature senescence, heat stress response, viral resistance, and basal immunity have been noted. Related genes in other species link the family to quantum yield, photochemical quenching, lignin content, and callus induction.
