Overexpression of <i>SEPALLATA3</i>-like Gene <i>SnMADS37</i> Generates Green Petal-Tip Flowers in <i>Solanum nigrum</i>.

ABSTRACT: The SEPALLATA3 (SEP3)-like MADS-box genes play crucial roles in determining petal identity and development in the petunia and tomato of Solanaceae. Solanum nigrum is a self-pollinating plant in the Solanaceae family, and produces white flowers. However, the mechanisms controlling the transition from green to white petals during flower development remain poorly understood. In this study, we isolated a flower-specific SEP3-like gene, SnMADS37, from S. nigrum, and investigated its potential role in chlorophyll metabolism during petal development. Our results show that quantitative RT-PCR analysis demonstrates that SnMADS37 is exclusively expressed in petals and stamens during early floral bud development. Overexpression of SnMADS37 clear
