SHD — Sorghum bicolor

Summary

SORBI_3008G111600, also known as SbSHD, encodes a heat shock protein 90 (HSP90) family member containing Hsp90 and ATPase domains. The gene is associated with ATP-dependent protein folding chaperone activity and has been linked to diverse molecular functions including CDP-glycerol diphosphatase, 2',3'-cyclic-nucleotide 2'-phosphodiesterase, and pectate lyase activities. SbSHD is associated with biological processes such as thylakoid membrane organization, de-etiolation, defense response to insects, telomere maintenance, and fatty acid beta-oxidation. The protein localizes to chloroplast thylakoids, the chloroplast inner membrane, and the ER lumen. SbSHD has been connected to agronomically important traits including flowering time, seed set, seed viability, pollen fertility, root development, plant growth, and responses to high temperature, salt, and bacterial disease. Studies of related genes in other species link the HSP90 family to thermotolerance, disease resistance, plastid function, and thylakoid membrane homeostasis.
