TB1 — Solanum tuberosum
Summary
PGSC0003DMG400005705, designated TB1, BRC1A or StTB1 on potato chromosome 3, encodes a TCP transcription factor (BRANCHED1A) with a CYC/TB1_R domain that localises to the nucleus and binds sequence-specific DNA. In potato, TB1 is associated with lateral shoot outgrowth, regulation of shoot development and secondary shoot formation, as well as flower development, cell growth, and the determination of dorsoventral asymmetry. The gene has been connected to abscisic acid metabolism and signalling, auxin anabolism, virus-induced PTGS, and homeostasis. Associations with agronomic traits include plant height, drought tolerance, and respiration rate. Related genes in other species link the family to fruit weight, shape and colour, seed weight, leaf thickness and chlorosis, and contents of lycopene, carotenoids, chlorophyll, cytokinin and sugar.
