CAB1 — Capsicum annuum

Summary

CaCAB1 (T459_05312) on pepper chromosome 2 encodes a chlorophyll a-b binding protein of the light-harvesting complex family, with annotated chlorophyll, xanthophyll, chitin and chitosan binding activities, as well as pheophytinase, chlorophyll b reductase, RCC reductase and pheophorbide a oxygenase activities. The gene is associated with photosynthesis light harvesting in both photosystems I and II, chlorophyll anabolism and breakdown, pigmentation, response to low light, desiccation, herbicide and drought, and regulation of the hypersensitive response. It localises to the thylakoid membrane, LHCII, photosystem I and II, and the chloroplast. Associations include fruit color, chlorophyll content and ratio, leaf yellowing tolerance, bacterial blight disease resistance, net photosynthetic rate, quantum yield, starch content, flowering time, root length, and responses to high and low temperature, oxidative stress and jasmonic acid.
