Transcriptome Analysis of the Barley-Rhynchosporium secalis Interaction
Leaf scald caused by the infection of Rhynchosporium secalis, is a worldwide crop disease resulting in significant loss of barley yield. In this study, a systematic sequencing of expressed sequence tags (ESTs) was chosen to obtain a global picture of the assembly of genes involved in pathogenesis. To identify a large number of plant ESTs, which are induced at different time points, an amplified...
متن کاملGenetic basis of control of Rhynchosporium secalis infection 4 and symptom expression in barley 5
10 Abstract The genetic basis of several different 11 components of resistance to Rhynchosporium secalis 12 in barley was investigated in a mapping population 13 derived from a cross between winter and spring 14 barley types. Both the severity of visual disease 15 symptoms and amount of R. secalis DNA in leaf 16 tissues were assessed in field trials in Scotland in the 17 2007/2008 and 2008/2009...
متن کاملRapid Detection and Quantification of Rhynchosporium secalis in Barley Using a Polymerase Chain Reaction
PCR primers for diagnosis of Rhynchosporium secalis in seed samples of barley were developed. For the quantification of the pathogen in seed samples a real-time PCR with SYBR Green approach was used. Amounts from 1.8 to 419.1 pg of R. secalis DNA per 100 ng of total DNA were detected in 18 samples of barley seeds contaminated by R. secalis in field conditions. The correctness of this quantitati...
متن کاملTwo new species of Rhynchosporium.
Rhynchosporium consists of two species, R. secalis and R. orthosporum. Both are pathogens of grasses with R. secalis infecting a variety of Poaceae hosts and R. orthosporum infecting Dactylis glomerata. Phylogenetic analyses of multilocus DNA sequence data on R. secalis isolates originating from cultivated barley, rye, triticale and other grasses, including Agropyron spp., Bromus diandrus and H...
متن کاملPhylogeographical analyses reveal global migration patterns of the barley scald pathogen Rhynchosporium secalis.
A phylogeographical analysis of the scald pathogen Rhynchosporium secalis was conducted using nuclear DNA sequences from two neutral restriction fragment length polymorphism loci and the mating-type idiomorphs. Approximately 500 isolates sampled from more than 60 field populations from five continents were analysed to infer migration patterns and the demographic history of the fungus. Migration...
