TBP1 — Cucumis melo

Summary

MELO3C015563.2 (CmTBP1) on melon chromosome 3 encodes a TATA-box binding protein, a core component of the transcription factor IID complex that binds DNA and interacts with TFIIB, RNA polymerase, and other transcription factors. The gene is associated with DNA-templated transcription initiation, nucleosome assembly, and regulation of cell growth. It is linked to fruit development and ripening, cotyledon and leaf morphogenesis, primary root development, and responses to hypoxia, heat, sucrose, and blue light. Associations with agronomic traits include yield, seed set, seed yield, nitrate content and sensitivity, nitrogen sensitivity, water stress response, cucurbit downy mildew response, aphid response, chlorophyll content, and stomatal resistance. The protein localises to the nucleus, chromatin, nucleolus, cytoplasm, plasmodesma, and plant-type cell wall.
