AGL2 — Solanum lycopersicum

Summary

SlAGL2 (AGL2) on tomato chromosome 2 encodes a protein containing MADS-box and K-box domains, with annotated activities including transcription regulator activity, DNA-binding transcription factor activity, and protein dimerization activity. In tomato, SlAGL2 is associated with leaf and root development, flowering, sepal growth, and plant height. The gene is linked to numerous floral and reproductive processes, including sepal morphogenesis, regulation of double fertilization, negative regulation of seed maturation and floral organ abscission, fruit abscission, and release of seed from dormancy. Associations extend to traits such as floral organ size and morphology, carpel shape and number, fruit ripening, inflorescence branching, seed coat hardness and color, and osmotic adjustment capacity. The protein localizes to the nucleus, cytoplasm, and plasmodesmata. Studies of related genes in other species link the MADS-box family to floral meristem determination, organ identity, and seed development.
