SCR — Cucumis melo

Summary

MELO3C025282.2, also known as CmSCR, CmSGR1 or CmSCL23, encodes a GRAS family transcription factor on melon chromosome 9. The protein localises to the nucleus, cytoplasm and Golgi, and exhibits sequence-specific DNA binding, transcription cis-regulatory region binding, protein homodimerisation and protein binding activities. In melon, CmSGR1 is associated with fruit ripening. The gene is linked to endoderm and bundle sheath cell fate specification, radial pattern formation, root morphogenesis, amyloplast organisation, negative gravitropism, regulation of root meristem size, arbuscular mycorrhizae formation, and responses to nutrients and symbiotic fungi. Associations with yield, leaf growth and development, root development traits including adventitious and lateral root number, root thickness, cell cycle and elongation traits, chlorophyll degradation, leaf senescence, and photosynthetic CO₂ assimilation have been recorded. Studies of related genes in other species connect it to root ground tissue patterning, endodermis development, quiescent centre formation, shoot radial organisation and gravitropism.
