Polymorphism of microsatellite markers on chromosomes 3H and 7H in barley genotypes resistant and susceptible to Rhynchosporium secalis

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...

Genetic 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...

Rapid 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...

on the relationship between using discourse markers and the quality of expository and argumentative academic writing of iranian english majors

the aim of the present study was to investigate the frequency and the type of discourse markers used in the argumentative and expository writings of iranian efl learners and the differences between these text features in the two essay genres. the study also aimed at examining the influence of the use of discourse markers on the participants’ writing quality. to this end the discourse markers us...
