AP1 — Solanum lycopersicum

Summary

SlAP1 (SOLYC05G056620.2) on tomato chromosome 5 encodes a MADS-box transcription factor, containing MADS-box and K-box domains, with RNA polymerase II transcription regulatory region sequence-specific DNA binding and protein dimerization activities. It is localized to the nucleus. SlAP1 is associated with flower formation, carpel formation, sepal development, inflorescence morphogenesis, compound leaf morphogenesis, leaf formation, fruit abscission, dehiscence, pigment accumulation, carotenoid metabolism, nutrient storage, and cell wall organization. The gene has been connected to traits including floral organ identity, meristem identity, fruit type, fruit size, fruit shape, sepal size, leaf shape, plant height, seed size, seed shattering, chlorophyll content, and salt tolerance. Related genes in other species are linked to sucrose content.
