SHR — Cicer arietinum

Summary

LOC101506038 (CaSHR, also known as CaEAL1 or CaSGR7) on chickpea chromosome 7 encodes a GRAS family transcription factor with sequence-specific DNA binding and protein homodimerization activity. The gene is associated with endoderm and bundle sheath cell fate specification, radial pattern formation, root morphogenesis, regulation of root meristem size, negative gravitropism, amyloplast organization, and response to nutrients and symbiotic fungi. It has been linked to yield, drought tolerance, leaf relative water content, stem senescence, root thickness, adventitious rootless, and leaf growth and development traits. Additional associations include chlorophyll degradation, leaf senescence, Casparian strip formation, asymmetric cell division, and photosynthetic CO2 assimilation. Studies of related genes in other species link the family to root stem cell niche maintenance, ground tissue formation, shoot radial organization, and mineral transport.
