TUBB1 — Solanum tuberosum

Summary

PGSC0003DMG400009938 (TUBB1, StTUB1) on potato chromosome 4 encodes a beta tubulin protein. The gene is associated with tubulin assembly, microtubule nucleation, plus-end directed microtubule sliding, and other microtubule-related processes. TUBB1 is associated with tuberisation, meiosis, fertility, and flower development, as well as with traits such as amylose content, beta-carotene and carotenoid content, sucrose content, flavonoid content, plant size, shoot branching, root number, and responses to nitrogen, zinc, UV-B light, and biotic stress. The encoded protein localises to the microtubule cytoskeleton, mitotic spindle, kinetochore, and gamma-tubulin complex. Studies of related genes in other species link the family to gametophyte development, cytokinesis, and microtubule nucleation.
