Cloning and functional analysis of downy mildew resistance gene RPF1 in spinach (Spinacia oleracea L.).
Downy mildew, caused by the obligate pathogen Peronospora effusa, is a devastating disease in spinach (Spinacia oleracea L.). Resistance to P. effusa is largely controlled by a dominant resistance locus RPF1, for which two candidate genes have been previously proposed but lacked functional validation. In this study, we...
