CASP1 — Sorghum bicolor

Summary

SORBI_3010G094400, designated SbCASP1, encodes a member of the CASP/CASPL protein family characterized by a CASP domain and associated with protein homodimerization and binding activities. In sorghum, this gene is linked to Casparian strip assembly and localization, cell-cell junction assembly, cell wall modification and organization, proteolysis, regulation of protein stability, and response to salt stress. It is also associated with root length and the SALTTL trait. The encoded protein localizes to the Casparian strip, plasmalemma, and mitochondria. Studies of related genes in other species connect the CASP family to root elongation, lateral root development, lignin deposition, calcium homeostasis, and tolerance.
