PSBE — Pisum sativum

Summary

PSAT0S6989G0160 (symbol PSBE, also known as PsPSBE) in garden pea (Pisum sativum) encodes a protein with the PSII_cytb559_asu_lum domain, a heme-binding protein with electron transfer activity and iron-binding capacity. The gene product localises to the photosystem II reaction centre within the chloroplast thylakoid membrane. PSBE is associated with the photosynthetic electron transport chain and with de-etiolation. Studies of related genes in other species link the PSBE family to seed weight, leaf size, plant height and root nodule number, though these associations are not yet established in pea itself.
