PPH — Camelina sativa

Summary

CSA08G005760, designated CsPPH (also known as CsCRN1 or CRN1) in Camelina sativa, encodes a protein with the PPH_chloroplastic domain and belongs to the alpha/beta hydrolase fold family. The gene product is associated with pheophytinase, RCC reductase, Chl b reductase, pheophorbide A oxygenase, and chlorophyll b synthesis activities, as well as Fe/S and chlorophyll binding. CsPPH localises to chloroplast membranes, thylakoids, and the apoplast. It is associated with the catabolic process of photosystem II-associated light-harvesting complex II, regulation of programmed cell death and the hypersensitive response, fruit and flower development, and defence responses to bacteria and other organisms. The gene has been connected to agronomically important traits including leaf yellowing tolerance, chlorophyll content and retention, leaf senescence, stem senescence, disease tolerance, seed germination and storability, photosystem efficiency, and root and cotyledon morphology.
