PSBE — Phaseolus vulgaris

Summary

PHAVU_002G090533, designated PSBE (PvPSBE) on chromosome 2 of French bean (Phaseolus vulgaris), encodes a protein with the PSII_cytb559_asu_lum, PSII_cyt_b559_CS, PSII_cyt_b559_N, PSII_cyt_b559_asu, and PSII_cyt_b559_asu_sf domains. The product has electron transfer activity, iron binding, and heme binding, and is localised to the chloroplast thylakoid membrane within the photosystem II reaction center. The gene is associated with the photosynthetic electron transport chain. Studies of related genes in other species link the PSBE family to agronomically important traits including seed weight, leaf size, plant height, and root nodule number.
