PPH — Camelina sativa

Summary

CsPPH (CSA20G019210) in Camelina sativa encodes a protein with a PPH_chloroplastic domain and an alpha/beta hydrolase fold, and is annotated with pheophytinase, RCC reductase, Chl b reductase, pheophorbide A oxygenase, and chlorophyll b synthesis activities, as well as Fe/S binding, chlorophyll binding, mRNA binding, and protein binding. It localises to chloroplast thylakoid and envelope membranes, the apoplast, mitochondria, and cytosol. The gene is associated with response to fructose, regulation of HR, PSII-associated light-harvesting complex II catabolic process, regulation of programmed cell death, fruit development, defense response to other organism, flower development, and defence response to bacteria. It is linked to leaf yellowing tolerance, hybrid incompatibility, stem senescence, cytokinin sensitivity, cotyledon morphology, light intensity response, chlorophyll content, leaf senescence, disease tolerance, root morphology, and numerous phenotypes including lesion-mimic leaves, stay-green in darkness, chlorophyll retention, and chlorophyll breakdown. Related genes in other species link the family to cell death, lesion formation, and pathogen resistance.
