FTM6 — Solanum lycopersicum

Summary

SOLYC02G077920.4, also known as FTM6 or SlFTM6, encodes a Squamosa Promoter Binding Protein (SBP/SPL) family member on tomato chromosome 2. The product possesses DNA-binding transcription activator activity and is associated with diverse biological processes including inflorescence morphogenesis, meristem determinacy, regulation of vegetative phase change, carotenoid and chlorophyll metabolism, pigment accumulation, dehiscence, and cell wall disassembly. The gene is linked to numerous agronomic traits such as fruit color, fruit shape, fruit size, seed set percent, bacterial blight disease resistance, plant male sterility, pollen fertility, anthocyanin content, chlorophyll content, leaf length, leaf shape, stem elongation, and whole plant size. It is also connected to responses to copper, low temperature stress, and cytokinin and gibberellic acid sensitivity. Studies of related genes in other species link the family to defense responses, fungal immunity, and thermotolerance.
