HCF136 — Phaseolus vulgaris

Summary

PHAVU_011G029800, symbol HCF136, encodes a Ycf48/Hcf136 family protein containing a PSII_CF48-like domain and a WD40/YVTN repeat-like domain superfamily. In French bean (Phaseolus vulgaris) on chromosome 11, the gene product is associated with plastid organization and cellular protein complex assembly, and localizes to multiple chloroplast compartments including the thylakoid lumen, stroma, envelope, and photosystem II. The gene is linked to photosystem II accumulation and stability. Studies of related genes in other species link the family to photosystem II assembly, thylakoid protein transport, and seedling lethality with no photosystem II activity, and sequence similarity connections extend to photochemical quenching traits.
