ABI5 — Cucumis sativus

Summary

CsABI5 (CSA_3G776860) on cucumber chromosome 3 encodes a bZIP transcription factor of the BZIP46-like family with DNA-binding transcription activator activity. The gene is associated with regulation of abscisic acid anabolism, TOR signaling, nitrate assimilation, salicylic acid metabolism, and responses to pH and salinity. It has been linked to numerous agronomic traits including seed protein content, endosperm storage protein content, seed set percent, inflorescence length, leaf elongation rate, whole plant size, plant male sterility, and responses to nitrogen, nitrate, phosphorus, aluminum, cadmium, copper, and manganese. Additional associations include vegetative to reproductive phase transition, plastid development, lignin biosynthesis, vascular tissue morphology, and wheat powdery mildew disease response. The gene product localizes to chromatin, nuclear bodies, the mediator complex, and ubiquitin ligase complexes.
