Marker-assisted selection (MAS) refers to the use of molecular markers to assist phenotypic selections in crop improvement. Several types of molecular markers, such as single nucleotide polymorphism (SNP), have been identified and effectively used in plant breeding. The application of next-generation sequencing (NGS) technologies has led to remarkable(More)
Ninety-six isolates of sunflower Sclerotinia sclerotiorum (Lib.) de Bary from Inner Mongolia (IM) in China, from Canada and the United Kingdom (UK) were sampled to investigate the genetic diversity and structure using Sequence-Related Amplified Polymorphism. A total of 123 polymorphic bands were obtained, ranging in size from 100 to 500 base pairs. The five(More)
Phoma stem canker (blackleg), caused by the fungi Leptosphaeria maculans and L. biglobosa, is the most devastating disease in oilseed rape (canola) production worldwide. In this study, 84 Leptosphaeria isolates were collected in China from rapeseed (Brassica napus) plants with blackleg symptoms and identified using multiplex PCR and rDNA-ITS sequence(More)
Leptosphaeria maculans and L. biglobosa, which cause phoma stem canker disease, are related pathogens of brassicas that were originally considered as one species but occupy slightly different ecological niches and are now reproductively isolated. Globally, the invasion by the more damaging L. maculans into areas where only L. biglobosa was present occurred(More)
The genetic diversity of specific Fusarium oxysporum f.sp. lini from six provinces in China was investigated using molecular markers, inter-simple sequence repeats (ISSR). Based on the morphological features and the internal transcribed spacer (ITS) sequences, 96 isolates were identified as Fusarium oxysporum. The 96 isolates were amplified by PCR with 12(More)
