PPH — Pisum sativum

Summary

PSAT5G211600 (PPH, PsPPH) encodes a protein with an alpha/beta hydrolase fold and is associated with pheophytinase activity, RCC reductase activity, Chl b reductase activity, pheophorbide A oxygenase activity, chlorophyll b synthesis activity, Fe/S binding, chlorophyll binding, mRNA binding, and protein binding. It is associated with the PSII-associated light-harvesting complex II catabolic process, regulation of programmed cell death, defense response to other organisms, immune response, fruit development, seed dehydration, and other biological processes. The gene is linked to traits including leaf yellowing tolerance, stay-green phenotype in darkness, chlorophyll retention, seed maturation, stem senescence, and disease tolerance. It localizes to chloroplast thylakoid and inner membranes, stroma, and envelope. Related genes in other species link the family to chlorophyll catabolism, cell death, and pathogen hypersensitivity.
