A transposon-mediate inactivation of a CYCLOIDEA-like gene originates polysymmetric and androgynous ray flowers in Helianthus annuus.

Genetica - 1 Dec 2011

Fambrini Marco, Salvini Mariangela, Pugliesi Claudio

Abstract excerpt

In several eudicots, including members of the Asteraceae family, the CYCLOIDEA (CYC) genes, which belong to the TCP class of transcription factors, are key players for floral symmetry. The sunflower inflorescence is heterogamous (radiate capitulum) with sterile monosymmetric ray flowers located in the outermost whorl of the inflorescence and hermaphrodite polysymmetric disk flowers. In inflorescence of...
