CAM1 — Sorghum bicolor

Summary

SORBI_3001G159700 (SbCAM1) on sorghum chromosome 1 encodes a protein with MFS sugar transporter domains and multiple annotated molecular functions including carbohydrate transmembrane transporter, symporter, ion channel, and S-nitrosoglutathione reductase activities. The gene is associated with diverse biological processes such as cellular responses to cold, drought, salinity, phosphate starvation, and nematodes, as well as lignin biosynthesis, lateral root formation, and arbuscular mycorrhizae formation. It localizes to the periarbuscular membrane, tonoplast, chloroplast envelope, and mitochondria. SbCAM1 is associated with traits including photosynthetic rate, stomatal opening and closure, flowering time, disease tolerance, salt stress response, root development, iron sensitivity and concentration, shoot branching, and stem elongation. Related genes in other species are associated with cadaverine sensitivity, drought and salt stress tolerance, formaldehyde detoxification, and thermotolerance.
