CAM — Triticum turgidum subsp. durum

Summary

TRITD6BV1G110690 (symbol CAM, also known as TtCAM and CBP60 family members) on durum wheat chromosome 6B encodes a calmodulin-binding protein with transcription coactivator activity, sequence-specific DNA binding, and calmodulin binding. It is associated with CAM photosynthesis, regulation of salicylic acid biosynthesis, calcium signaling, defense response, oxidative stress response, and photomorphogenesis. The gene has been linked to numerous agronomic traits including seed weight, water use efficiency, photosynthetic rate, stomatal resistance, flowering time, root morphology, leaf growth, anthocyanin content, and abscisic acid sensitivity. It localizes to the nucleus, cytosol, cytoplasm, plasma membrane, and vacuole. Studies of related genes in other species connect the family to plant immunity, disease resistance, photomorphogenic growth, and organ size regulation.
