CAM — Triticum turgidum subsp. durum

Summary

TRITD6AV1G056010, designated TtCAM on durum wheat chromosome 6A, encodes a calmodulin-binding protein of the CBP60 family with transcription coactivator activity, calmodulin binding, sequence-specific DNA binding, and transcription factor activity. The gene is associated with CAM photosynthesis, regulation of salicylic acid biosynthesis, calcium signaling, defense responses, oxidative stress responses, and photomorphogenesis. It localizes to the nucleus, cytosol, cytoplasm, plasma membrane, and vacuole. TtCAM is linked to numerous agronomic traits including seed weight, water use efficiency, photosynthetic rate, stomatal resistance, flowering time, root morphology, leaf growth and development, anther and pistil morphology, anthocyanin content, and abscisic acid sensitivity. Related genes in other species are associated with plant immunity, disease resistance, organ size, and seed size.
