In addition to sequence information on two contigs around the disease resistance gene Rdr1 additional sequence information will be obtained on parts of the genomic region from a third species. The main part of the project will be concerned with isolation of a larger sample RGA paralogues from natural populations of the diploid rose species R. arvensis. In addition a screen for RGA allele variation using an SSR marker embedded in a conserved part of the RGA LRR region will be performed both in a larger sample of R. arvensis plants and a sample from populations of R. canina a pentaploid with largely apomictic reproduction. The data will significantly complement the sequence data from the two contigs and sequences of individual RGA from related species obtained within the running project. These data will help to analyse the evolutionary history and factors influencing molecular diversity of a TIR-NBS-LRR family in woody perennial roses.

除了抗病基因Rdr 1周围两个重叠群的序列信息外，还将获得第三个物种基因组区域部分的序列信息。该项目的主要部分将涉及从二倍体玫瑰物种R.阿文西斯此外，将在较大的R. arvensis植物和来自R.犬科动物为五倍体，主要为无融合生殖。这些数据将显著补充来自两个重叠群的序列数据和在运行项目中获得的相关物种的单个RGA的序列。这些数据将有助于分析木本多年生月季TIR-NBS-LRR家族的进化历史和影响分子多样性的因素。
