Tissue-specific promoters can drive genes specifically expressed in the target organs and have been widely used in plant molecular breeding. In this study, a 1.2-kb promoter region of an anther-specific gene PhLRR from Petunia hybrida “Fantasy” was isolated and fused to the β-glucuronidase (GUS) gene. The pPhLRR::GUS vector was heterogeneously transformed(More)
An anther-specific GRP gene, regulated by PhMYC2 , causes a significant reduction of male fertility when overexpressed in petunia, and its promoter is efficient in genetic engineering of male-sterile lines. Glycine-rich proteins (GRPs) play important roles in plant anther development; however, the underlying mechanisms and related regulatory networks are(More)
