BIT1 — Cucumis sativus

Summary

CsBIT1 (CSA_3G740790) on cucumber chromosome 3 encodes an uncharacterized protein with DNA-binding transcription factor activity and ubiquitin ligase activity, associated with the Cul4-RING E3 ubiquitin ligase complex. The gene is linked to axillary shoot meristem initiation, anthocyanin metabolism, and positive regulation of flavonoid anabolism. It is associated with photoperiod-sensitive flowering time, blue light signaling, entrainment of circadian clock, and response to UV-B. Associations include traits such as anthocyanin and chlorophyll content, leaf size, seed growth and development, stem diameter, stamen length, trichome morphology, and responses to abiotic stresses including low temperature stress response, salt tolerance, and drought tolerance. The gene is also linked to brassinosteroid sensitivity, ethylene sensitivity, regulation of stomatal movement, and viral disease response. Related genes in other species connect the family to photomorphogenesis, circadian clock entrainment, and stress tolerance.
