The function of the HAM59 MADS-box gene in sunflower (Helianthus annuus L.) was studied to clarify homeotic C activity in the Asteraceae plant family. For the first time, transgenic sunflower plants with a modified pattern of HAM59 expression were obtained. It was shown that the HAM59 MADS-box transcription factor did mediate C activity in sunflower. In particular, it participated in termination of the floral meristem, repression of the cadastral function of A-activity, and together with other C-type sunflower protein HAM45-in the specification of the identity of stamens and pistils.
为阐明菊科植物中的同源异型C活性，对向日葵（Helianthus annuus L.）中HAM59 MADS盒基因的功能进行了研究。首次获得了具有改变的HAM59表达模式的转基因向日葵植株。结果表明，HAM59 MADS盒转录因子确实介导了向日葵中的C活性。具体而言，它参与了花分生组织的终止，抑制了A活性的边界功能，并与其他C型向日葵蛋白HAM45一起参与雄蕊和雌蕊身份的确定。
