AT3 — Capsicum annuum

Summary

CaAT3 (AT3) on pepper chromosome 3 encodes an embryonic abundant protein 1, a member of the LEA_5 and small hydrophilic seed protein families. The gene product is annotated with L-lactate dehydrogenase (cytochrome) activity and protein phosphorylated amino acid binding. CaAT3 is associated with embryo development ending in seed dormancy, acquisition of desiccation tolerance in seed, fruit development, response to abscisic acid, fermentation, protein stabilization, secondary metabolism, and signal transduction. It localizes to the cytosol, cytoplasm, and nucleus. The gene has been connected to pungency, fruit weight, root morphology, capsiate content, seed dehydration, and seed development. Related genes in other species link the family to seed dormancy, embryo development, seed maturation, and late embryogenesis.
