SVP — Solanum lycopersicum

Summary

SOLYC11G010570.2 (SVP, also known as SlFAQ1, STMADS11, AGL22) on tomato chromosome 11 encodes a protein containing MADS-box and K-box domains, with annotated activities including DNA-binding transcription regulator activity, RNA polymerase II-specific transcription factor activity, transcription corepressor activity, and mRNA regulatory element binding translation repressor activity. The gene is associated with inflorescence morphogenesis, floral whorl development, maintenance of inflorescence meristem identity, and negative regulation of seed maturation and floral organ abscission. It has been linked to numerous traits including fruit number, fruit ripening, sepal size, flower number, inflorescence branching, seed shattering, photoperiod sensitivity, temperature stress response, and aphid response. Localization evidence connects the protein to euchromatin, heterochromatin, plasmodesmata, and the plant cell wall. Studies of related genes in other species link the family to flowering time regulation, thermosensory flowering, floral meristem determination, and circadian clock regulation.
