TUBA1 — Solanum tuberosum

Summary

PGSC0003DMG400008752 (TUBA1) on potato chromosome 8 encodes an alpha tubulin protein, a core component of microtubules. The gene product is associated with microtubule dynamics, including plus-end directed sliding, nucleation, and phragmoplast and mitotic spindle organization. TUBA1 is linked to diverse agronomic traits such as reducing sugar and starch content, sucrose levels, nitrogen sensitivity, phosphorus uptake, root and shoot architecture, and responses to biotic stress, UV-B, and osmotic conditions. It has been connected to phenotypes including microgravity response, cortical microtubule organization, fertility, meiosis, trichome and leaf development, and cell expansion. Related genes in other species link the family to lateral root development, nuclear shape, centromere architecture, anisotropic cell expansion, and helical root growth.
