CAB1 — Glycine max

Summary

GLYMA_05G128000V4 (GmCAB1) encodes a chlorophyll a-b binding protein of the light-harvesting complex, localised to the thylakoid membrane and photosystems I and II. The gene is associated with photosynthesis, light harvesting in both photosystems, thylakoid membrane organisation, and responses to UV-A and fructose. It has been linked to numerous agronomic traits including leaf chlorophyll content, photosynthetic rate, seed weight and size, stem dry weight, specific leaf weight, leaf area index, starch and protein content, germination rate, vegetative growth time, and senescence. Associations also include chloroplast development, photoprotection, non-photochemical quenching, electron transport, jasmonic acid content, and defence against herbivores and pathogens. Studies of related genes in other species link the family to thylakoid biogenesis, chlorophyll b biosynthesis, circadian rhythm, and photooxidative stress tolerance.
