CASP1 — Sorghum bicolor

Summary

SORBI_3006G273300, designated SbCASP1, encodes a CASP/CASPL family protein containing a CASP domain and is associated with protein homodimerization and binding activities. The gene is linked to Casparian strip assembly and localization, cell-cell junction assembly, cell wall modification and organization, regulation of protein stability, proteolysis, and response to salt stress. SbCASP1 has been connected to root length and salt tolerance traits, as well as Casparian strip formation. The protein localizes to the Casparian strip, plasmalemma, and mitochondria. Studies of related genes in other species link the CASP family to root elongation, lateral root development, lignin deposition, calcium homeostasis, and tolerance responses.
