CAM — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0585520 (HvCAM) on barley chromosome 6H encodes a calmodulin-binding protein of the CBP60 family with transcription coactivator activity, sequence-specific DNA binding, and calmodulin binding. The gene is associated with the regulation of salicylic acid biosynthesis, calcium signaling, defense responses to fungi and other organisms, photomorphogenesis, root meristem growth, seed germination, and cell death. It has been linked to numerous agronomic traits including seed weight, water use efficiency, photosynthetic rate, flowering time, anthocyanin content, root hair length, leaf morphology, and abscisic acid sensitivity. The protein localizes to the nucleus, cytosol, plasma membrane, and plant-type vacuole. Studies of related genes in other species connect the family to plant immunity and disease resistance, and to photomorphogenic growth, organ size, and leaf development.
