CAM — Triticum turgidum subsp. durum

Summary

TRITD6AV1G114800 (symbol CAM, also known as TtCAM) on durum wheat chromosome 6A 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 responses, oxidative stress responses, photomorphogenesis, root meristem growth, and chlorophyll fluorescence. The gene product localizes to the nucleus, cytosol, cytoplasm, plasma membrane, and plant-type vacuole. Associations with agronomic traits include seed weight, water use efficiency, photosynthetic rate, stomatal resistance, flowering time, leaf and root morphology, anthocyanin content, abscisic acid sensitivity, and disease resistance. Related genes in other species link the family to plant immunity and pathogen defense, photomorphogenesis, organ growth, and leaf development.
