MP — Cucumis melo

Summary

MELO3C003768.2 (symbol MP, also known as CmMP, CmIAA24, IAA24, CmARF5, ARF5) on melon chromosome 5 encodes a protein with DNA binding and transcription cis-regulatory region binding activity, containing ARF, AUX/IAA, B3 DNA-binding, and PB1-like domains. It is associated with auxin export across the plasma membrane, hormone metabolism, phloem and sieve cell differentiation, inflorescence meristem growth, embryonic pattern specification, and regulation of leaf senescence and root development. The gene is linked to numerous traits including fruit shape, stem angle, leaf and vascular morphology, adventitious and lateral root number, shoot growth angle, phototropism, phyllotaxy, osmotic response sensitivity, ethylene sensitivity, and sulfur content. Studies of related genes in other species connect the family to fruit size, plant height, water use efficiency, cold stress tolerance, and vascular tissue development.
