PPH — Camelina sativa

Summary

CsPPH (CSA13G016520) encodes a pheophytinase, an alpha/beta hydrolase-fold protein with pheophytinase, RCC reductase, Chl b reductase, pheophorbide A oxygenase, and chlorophyll b synthesis activities, along with Fe/S, chlorophyll, mRNA, and protein binding. It is associated with chlorophyll breakdown, leaf senescence, fruit and flower development, defense responses to bacteria and other organisms, regulation of programmed cell death and the hypersensitive response, and response to fructose. The protein localizes to chloroplast thylakoid membranes, inner membrane, envelope, and stroma, as well as mitochondria, apoplast, and cytosol. Traits linked to CsPPH include leaf yellowing tolerance, chlorophyll content, stem senescence, cytokinin sensitivity, hybrid incompatibility, disease tolerance, and root and cotyledon morphology. Studies of related genes in other species connect the family to cell death, lesion formation, pathogen hypersensitivity, and chlorophyll catabolism.
