ful — Solanum lycopersicum

Summary

SOLYC06G069430.3, known as FUL, FUL1, FUL2, or AGL8 in tomato (Solanum lycopersicum) on chromosome 6, encodes a MADS-box transcription factor containing MADS-box and K-box domains. It has RNA polymerase II transcription regulatory region sequence-specific DNA binding and protein dimerization activities, and localizes to the nucleus. The gene is associated with flower formation, sepal development and morphogenesis, fruit ripening, fruit morphology and tip development, leaf size, and flowering time. It is linked to numerous fruit traits including size, shape, weight, firmness, color, and ripening, as well as carotenoid and lycopene content, chlorophyll content, anthocyanin content, seed shattering, seed size and dormancy, plant height, stem diameter, inflorescence number and branching, heterosis, photosynthetic rate, stomatal resistance, and ethylene sensitivity. Studies of related genes in other species link the family to fruit morphology, grain size, drought tolerance, and pathogen resistance.
