ABI5 — Cicer arietinum

Summary

LOC101506390 (CaABI5) on chickpea chromosome 3 encodes a bZIP transcription factor of the BZIP46-like family, annotated with DNA-binding transcription activator activity and additional molecular functions including protein phosphatase binding, SUMO transferase activity, and cis-regulatory region sequence-specific DNA binding. The gene is associated with regulation of abscisic acid anabolism, positive regulation of TOR signaling, response to calcium ions, root hair cell differentiation, and amino acid metabolic processes. It localizes to the THO complex, PP2A complex, mediator complex, chromatin, and nuclear bodies. CaABI5 is linked to numerous agronomic traits including seed set percent, endosperm storage protein content, plant male sterility, vegetative to reproductive phase transition, leaf elongation rate, whole plant size, and responses to aluminum, cadmium, copper, magnesium, manganese, nitrate, nitrogen, and phosphorus. Related genes in other species are associated with abscisic acid responsiveness, seed germination, salt and osmotic stress tolerance, root architecture, and seed longevity.
