TUBB — Cicer arietinum

Summary

TUBB on chickpea chromosome 9 encodes a beta-tubulin protein, a structural constituent of the cytoskeleton. It is associated with microtubule-based processes, including plus-end directed microtubule sliding, vesicle transport along microtubule, and cortical microtubule organization, as well as mitotic cell cycle, meristem growth, and seed trichome elongation. The gene has been linked to numerous traits, including plant growth and development, root and shoot morphology, leaf growth and development, leaf senescence, seed growth and development, days to flowering, and responses to abiotic stresses (such as ozone, oxidative stress, and nitrogen sensitivity) and biotic stresses (including disease tolerance). Localization evidence places the product at the microtubule, cell plate, nuclear envelope, and plant-type cell wall. Studies of related genes in other species link the beta-tubulin family to helical growth, cell plate formation, pathogen defense, and seed germination.
