SCR — Cicer arietinum

Summary

LOC101513767 (CaSCR, also known as CaSGR1) on chickpea chromosome 3 encodes a GRAS family transcription factor with sequence-specific DNA binding and protein homodimerization activity. This gene is associated with regulation of root meristem size, root morphogenesis, radial pattern formation, bundle sheath cell fate specification, amyloplast organization, negative gravitropism, and arbuscular mycorrhizae formation. It is linked to yield, drought tolerance, leaf relative water content, adventitious root number, root thickness, cell cycle and elongation traits, chlorophyll degradation, leaf senescence, photosynthetic CO₂ assimilation, and seed degreening. The encoded protein localizes to the nucleus, cytoplasm, and Golgi complex. Studies of related genes in other species link the family to root radial patterning, endodermis development, quiescent center maintenance, stem cell niche specification, and shoot gravitropism.
