SVP — Solanum tuberosum

Summary

PGSC0003DMG400033570, designated StSVP (also known as STMADS11, AGL22, or StAGL22) on potato chromosome 1, encodes a protein with MADS-box, MEF2-like, and K-box domains. The protein exhibits DNA-binding transcription factor activity, RNA polymerase II-specific regulatory region sequence-specific DNA binding, transcription corepressor activity, and protein heterodimerization activity. StSVP is associated with floral whorl development, maintenance of inflorescence and floral meristem identity, meristem determinacy, photoperiodism, and reproductive structure development. It is linked to negative regulation of seed maturation and floral organ abscission, fruit abscission and dehiscence, gibberellin catabolism, and inhibition of brassinosteroid signalling. Associations include numerous floral and inflorescence morphology traits, photoperiod-sensitive flowering time, fruit number and ripening, seed yield and viability, leaf and shoot architecture, starch and lignin content, sulfur content, temperature stress response, and aphid response.
