CASP1 — Sorghum bicolor

Summary

SORBI_3007G001300, designated SbCASP1, encodes a CASP/CASPL family protein with a CASP domain and protein homodimerization and binding activities. It is associated with Casparian strip assembly and localization, cell-cell junction assembly, cell wall modification and organization, proteolysis, regulation of protein stability, and response to salt and salinity. Associations with root length and salt tolerance have been recorded. The gene is also linked to mitochondria and the plasmalemma. Related genes in other species connect the family to root elongation, lateral root development, lignin deposition, calcium homeostasis, and tolerance.
