Figure 1From: Cloning and phylogenetic analyses of serine/threonine kinase class defense-related genes in a wild fruit crop 'chestnut rose'The PCR amplification of STK genes from chestnut rose. The figure showed two samples: Lane 1, Rosa roxburghii cv. Guinong No.6 which is resistant to powdery mildew disease; and Lane 2, R. roxburghii cv. Guinong No.5 which is susceptible to powdery mildew disease.Back to article page
