ORES — Brachypodium distachyon

Summary

BdORES (BRADI_3G03112V3) on chromosome 3 of Brachypodium distachyon encodes a protein kinase with serine/threonine and tyrosine kinase activities, calmodulin binding, and RNA polymerase II CTD heptapeptide repeat kinase activity. The gene is associated with cell cycle regulation, including G2/M phase transition, DNA replication and damage checkpoints, and G1/S phase control. It has been linked to guard mother cell division, asymmetric cell division, gametophyte development, and meiotic nuclear division. Associations with traits include shoot apical meristem development, trichome morphology, cell elongation, leaf composition, seed growth, and plant growth and development. The gene is also linked to photomorphogenesis, red light signaling, circadian rhythm, endoreduplication, root growth, DNA damage response, and salt stress response. Studies of related genes in other species link the family to cell cycle arrest, microtubule dynamics, and mitosis-to-endocycle transitions.
