CAD — Sorghum bicolor

Summary

SORBI_3010G072100 (SbCAD) encodes a cinnamyl-alcohol dehydrogenase (EC 1.1.1.195) with aryl-alcohol, coniferyl-alcohol, 8-hydroxygeraniol and mannitol dehydrogenase activities, belonging to the CAD-like protein family. In sorghum, this gene is associated with C4 photosynthesis, phenylpropanoid and secondary metabolite metabolism, green leaf volatile production, alkaloid metabolism, and defense responses to bacteria, including hypersensitive response-programmed cell death and signal transduction. It is linked to water response, apoplast, cytosol and plasma membrane localisation, and traits including lignin content, photosynthetic rate, reproductive period, IAA content, disease and bacterial resistance, arsenic translocation and tolerance, salicylic acid accumulation, basal thermotolerance, C6-alcohol production, herbivore predator attraction, panicle and tiller development, height, leaf area, flowering date, and ethanol yield. Studies of related genes in other species connect the CAD family to lignin composition, plant defense, ovule development and flowering time.
