Overexpression of a MADS-box gene from birch (Betula platyphylla) promotes flowering and enhances chloroplast development in transgenic tobacco.

In this study, a MADS-box gene (BpMADS), which is an ortholog of AP1 from Arabidopsis, was isolated from birch (Betula platyphylla). Transgenic Arabidopsis containing a BpMADS promoter::GUS construct was produced, which exhibited strong GUS staining in sepal tissues. Ectopic expression of BpMADS sig...
