TUBB1 — Solanum lycopersicum

Summary

SOLYC04G081490.3 (TUBB1) on tomato chromosome 4 encodes a beta-tubulin protein. The gene is associated with microtubule dynamics, nucleation, and sliding, as well as with the gamma-tubulin complex and mitotic spindle localisation. In tomato, TUBB1 is linked to a wide range of agronomically important traits including root weight, lycopene and carotenoid content, nitrogen and zinc sensitivity, phosphorus uptake, shoot branching, inflorescence and anther morphology, seed coat traits, and biotic stress response. It is also connected to phenotypes such as reduced seed set, defective gametophytes, impaired meiosis, and altered trichome and leaf architecture. Studies of related genes in other species link the family to nuclear shape, centromere architecture, lateral root development, and anisotropic cell expansion.
