MP — Cucumis sativus

Summary

CsMP (CSA_3G866510) on cucumber chromosome 3 encodes a protein with ARF, AUX/IAA, B3 DNA-binding, and PB1-like domains, classified as an auxin response factor (ARF) family member. It is associated with sieve cell differentiation, phloem development, inflorescence meristem growth, embryonic pattern specification, and lateral root morphogenesis. The gene is linked to auxin polar transport and export, blue light signaling, and positive regulation of leaf senescence. Traits connected to CsMP include fruit size and growth, leaf and vascular morphology, shoot and root architecture, phototropism, phyllotaxy, and sulfur content. Phenotypic associations involve root growth and branching, protophloem differentiation, auxin-responsive cell growth, flowering time, and ethylene sensitivity. Studies of related genes in other species link the family to vascular tissue development, root meristem growth, and stress responses.
