The Hengduan Mountains is the core of the Sino-Himalayan Floristic Region. Different views have been postulated from phylogeographic studies in understanding the historical biological events shaping present-day distributions and species diversities in this area. We analyzed the phylogeography of Rosa soulieana, a widely distributed rose species in dry and(More)
Powdery mildew is one of the most important crop diseases worldwide. Genetic analysis has revealed that mutant alleles of the Mlo gene cause broad-spectrum resistance against pathogens found in cereal. In this study, the possibility of inducing powdery mildew (Podosphaera pannosa) resistance via transgenic technology in the rose was examined. The transgenic(More)
Phyllody is a flower abnormality in which leaf-like structures replace flower organs in all whorls. Here, we investigated the origin and the molecular mechanism of phyllody phenotype in Rosa chinensis cv. Viridiflora, an ancient naturally occurring Chinese mutant cultivar. Reciprocal grafting experiments and microscopy analyses, demonstrated that the(More)
