CAM — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0170810 (HvCAM) on barley chromosome 2H encodes a calmodulin-binding protein of the CBP60 family with transcription coactivator activity, calmodulin binding, and sequence-specific DNA binding. It is associated with regulation of salicylic acid biosynthesis, calcium signaling, defense responses to fungi and other organisms, photomorphogenesis, seed germination, root meristem growth, and cell death. The gene is linked to traits including seed weight, water use efficiency, photosynthetic rate, flowering time, anthocyanin content, root hair length, leaf morphology, anther and ovary development, and abscisic acid sensitivity. Studies of related genes in other species connect the family to plant immunity and disease resistance, photomorphogenic growth, organ size, and leaf development.
