Association between single nucleotide polymorphisms in the XRCC1 gene and susceptibility to prostate cancer in Chinese men.

Background: Prostate cancer (Pca) is one of the most common complex and polygenic diseases in men. The X-ray repair complementing group 1 gene (XRCC1) is an important candidate in the pathogenesis of Pca. The purpose of this study was to evaluate the association between single nucleotide polymorphisms in the XRCC1 gene and susceptibility to Pca.

[Identification of markers linked to resistance locus of Marssonina leaf spot in poplars by bulked segregant analysis(BSA)].

DNA markers linked to resistance locus of Marssonina leaf spot in poplars were found by bulked segregant analysis(BSA). The bulks consisted of individual with a extreme phenotype taken from a population of 91 F1 clones,which is a progeny of Populus deltoides Bartr.cv.
