AT2G36270 — Arabidopsis thaliana

Summary

AT2G36270, known as ABI5, encodes a with DNA-binding transcription activator activity and additional annotated molecular functions including protein phosphatase binding, SUMO transferase activity, and aromatic aminotransferase activity. In Arabidopsis, ABI5 is associated with seed dormancy maintenance, germination inhibition, secondary dormancy, and pre-harvest sprouting. The gene is linked to virus and geminivirus resistance, nematode resistance and susceptibility to Heterodera schachtii, aluminum tolerance, triacylglycerol accumulation, and hypocotyl growth. ABI5 is associated with chlorophyll a breakdown, pigment accumulation, energy homeostasis, TOR signaling, and responses to pH. The protein localizes to chromatin, nuclear bodies, the PP2A complex, and the mediator complex. Studies of related genes in other species link the ABI5 family to photosynthesis, chilling stress response, fruit firmness, and flavonoid content.
