Differential gene behavior in barley plants challenged with biotrophic and necrotrophic pathogens
Data showed that barley plants triggered different defense mechanisms to strengthen their B. graminis and C. sativus resistance, and the expression patterns of the same defense-associated genes were altered in adaptation to each pathogen.
Expression of PAL and PR2 pathogenesis related genes in barley plants challenged with closely related Pyrenophora species
The obtained results suggest that PAL and PR2 genes, positively regulate P. teres and P. graminea—resistance in barley plants during disease progress, which can provide testable hypotheses that will need direct future tests to determine how these changes may be specified in the genome of these closely related Pyrenophora species.
Pathogenic Groups Identified Among Isolates of Rhynchosporium secalis
pathogenic groups of R. secalis were identified to obtain a global picture of the assembly of isolates involved in Syrian populations which is essential for the development of scald-resistant barley cultivars.
CHANGES IN SALICYLIC ACID AND GENE EXPRESSION LEVELS DURING BARLEY-BLUMERIA GRAMINIS INTERACTION
An insight is provided into the signaling pathway that accounts for classical gene expression changes elicited during barley-Bgh interactions, which might be evidence that SA plays a positive role in signaling events during fungal infection by Bgh.

The idea that SA signaling and PR2 play a role in barley NB reduction is strengthened, as RT-PCR analysis revealed that PR2 expression increases in the resistant and susceptible genotypes over the inoculation time points, with maximum expression observed 6 dpi.
Barley transcript regulation as Rhynchosporium secalis changes its trophic lifestyle.
Differentially and significantly accumulating transcripts either unique or common between susceptible and resistant barley genotypes suggest distinct defense responses based on the pathogen trophic lifestyle.
MOLECULAR AND PATHOGENIC VARIATION IDENTIFIED AMONG ISOLATES OF RHYNCHOSPORIUM SECALIS FROM SYRIA
The fungus Rhynchosporium secalis is the causal agent of barley scald disease. Sixty-three isolates of diverse geographical origin within Syria were analyzed for pathogenicity and variability of…
Diallel Analysis of Barley Resistance to Blumeria graminis
Powdery mildew, caused by Blumeria graminis f. sp. hordei (Bgh) is a common foliar disease of barley worldwide. The creation of new cultivars with durable resistance to Bgh is highly desirable. Thi...

Results suggest that SA and H₂O₁ accumulation are important during both compatible and incompatible barley- C. sativus interactions.
