CAM1 — Sorghum bicolor

Summary

SbCAM1 (SORBI_3001G159600) on sorghum chromosome 1 encodes a protein with multiple transporter domains, including MFS sugar transport and sugar transporter signatures, and is annotated with diverse molecular functions such as vitamin Bt transporter activity, S-nitrosoglutathione reductase activity, carbohydrate transmembrane transporter activity, and chaperone protein binding. The gene is associated with responses to cold, drought, salinity, and nematodes, as well as leaf senescence, seed development, heat acclimation, and lignin anabolism. It localizes to the periarbuscular membrane, tonoplast, chloroplast envelope, and mitochondria. Traits linked to SbCAM1 include iron sensitivity and concentration, shoot axis branching, stomatal opening, photosynthetic rate, flowering time, disease tolerance, and root development. Studies of related genes in other species connect the family to cadaverine sensitivity, drought and salt stress tolerance, formaldehyde detoxification, and thermotolerance.
