Cloning of two classes of PR genes and the development of SNAP markers for powdery mildew resistance loci in chestnut rose (Rosa roxburghii Tratt)


Pathogenesis-related (PR) genes were isolated from chestnut rose (Rosa roxburghii Tratt) using a PCR approach with degenerate primers designed for the conserved regions of two PR gene families: class 2 (β-1,3-glucanase) and class 5 (osmotin). Thirteen PR2 and ten PR5 genes were obtained, with a nucleotide identity that ranged from 40.1 to 99.7% and from 99… (More)
