AP2 — Solanum lycopersicum

Summary

SlAP2 (SOLYC02G064960.3) on tomato chromosome 2 encodes a DNA-binding transcription corepressor with an AP2/ERF domain, belonging to the AP2/ERF superfamily. It is associated with diverse biological processes including flower formation, sepal morphogenesis, regulation of seed development, sporangia development, and lycopene anabolism. The gene has been connected to numerous agronomic traits such as fruit firmness, fruit color, fruit shape and size, plant height, flowering time, drought tolerance, chlorophyll content, net photosynthetic rate, root morphology traits, and germination rate. It is linked to floral organ identity, inflorescence architecture, seed mass, and vegetative phase change. Studies of related genes in other species connect the family to flower development, seed development, and ovule number.
