CAM — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0569980 (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. It is associated with the regulation of salicylic acid biosynthesis, calcium signaling, defense responses to fungi and other organisms, photomorphogenesis, root meristem growth, seed germination, cell death, and signal transduction. The gene has been linked to numerous agronomic traits including seed weight, water use efficiency, photosynthetic rate, flowering time, root morphology, leaf growth, anther and ovary development, anthocyanin content, and abscisic acid sensitivity. It localizes to the nucleus, cytosol, cytoplasm, plasma membrane, and plant-type vacuole. Related genes in other species connect the family to photomorphogenic growth, primary root elongation, and abscisic acid response.
