CAB — Solanum tuberosum

Summary

PGSC0003DMG400021287, designated CAB (synonyms StLHCA3, StCAB8, LHCA3, CAB8) on potato chromosome 10, encodes a chlorophyll a-b binding protein. The product possesses dual-specificity protein kinase activity and MEKK activity, binds chlorophyll, ATP, mRNA, metal ions, and phosphorylated amino acids, and localises to the photosystem I antenna complex, reaction centre, thylakoid membrane, and chloroplast envelope. The gene is associated with photosynthesis, light harvesting in photosystem I, response to low and high light intensity, stomatal closure, seed longevity, germination regulation, starch and wax anabolism, secondary metabolism, lipid metabolism, sugar-mediated signalling, detoxification, memory, and regeneration. It has been linked to traits including far-red light sensitivity, metabolite content, seed longevity, abiotic stress response, stomatal resistance, leaf senescence, flowering time, root morphology, salt tolerance, and plant growth and development.
