“…From ITS regions, the data obtained for all the sequences of Cochliobolus and Pyrenophora were consistent with the results reported in previous studies for Pyrenophora graminea, P. teres, and P. teres f. maculate (Carlsen et al, 2017;Poudel et al, 2019) and for several species of Bipolaris (Manamgoda et al, 2014). The genetic differences observed between isolates of C. sativus and P. teres, collected from different cereal-growing regions in Mexico, could explain the difference in virulence (Christensen, 1926;Sultana et al, 2018). In this sense, a study that evaluated a barley core collection for SFNB reaction revealed distinct genotype-specific pathogen virulence and host susceptibility (Neupane et al, 2015).…”

Barley (Hordeum vulgare) is generally used for animal feed, and food and beer production industries. Its production is affected by phytopathogens, of which Ramularia collo-cygni, Puccinia spp., Pyrenophora teres and Cochliobolus sativus are of global concern. In Mexico, there are few studies available on the morphological and molecular identification of fungi responsible for causing fungal diseases of barley. Therefore, the objective of this work was to identify, morphologically and molecularly, fungi isolated from barley seeds. The strains were identified by morphological analysis and by sequencing of the conserved ITS1/5.8s/ITS2 region of the ribosomal gene. Morphologically, the strains were identified as P. teres and C. sativus, which was confirmed with bioinformatics techniques using BLAST and MEGA6 programs. The results showed that the strains isolated from barley seeds in the highlands of Mexico were consistent with the sequences of P. teres and C. sativus deposited in the GenBank. These results will allow identifying some of the species of native fungi found in barley seeds.

“…Affected plants result in fewer tillers and grains per spike, as well as reduced seed germination, plant growth, and yield. In particular, yield reduction by C. sativus can reach up to 30% (Kumar et al, 2002;Ghazvini and Tekauz, 2007;Al-Sadi and Deadman, 2010;Sultana et al, 2018).…”

“…Kang et al [49] observed significant variation in the pathogenicity of 262 B. sorokiniana isolates from wheat samples in 97 locations of China. Similarly, variation in the aggressiveness of B. sorokiniana isolates was reported by several authors [8,50]. However, no considerable difference was found among the pathogenicity of B. sorokiniana isolates from Mexico and India [51,52].…”

Spot blotch caused by Bipolaris sorokiniana is a destructive disease of wheat worldwide. This study investigated the aggressiveness of B. sorokiniana isolates from different wheat-growing areas of Bolu province in Turkey on the cultivar Seri-82. Host susceptibility of 55 wheat cultivars was evaluated against the most aggressive isolate. Our results indicated that the cultivars Anafarta and Koç-2015 were the most resistant. A specific and sensitive qPCR assay was developed for detecting the pathogen in plant tissues and evaluating wheat plants with different resistance levels. Three primer sets, BsGAPDHF/BsGAPDHR, BsITSF/BsITSR, and BsSSUF/BsSSUR, were designed based on glyceraldehyde-3-phosphate dehydrogenase, internal transcribed spacers, and 18S rRNA loci of B. sorokiniana with detection limits of 1, 0.1, and 0.1 pg of pathogen DNA, respectively. The qPCR assay was highly sensitive and did not amplify DNA from the other closely related fungal species and host plants. The protocol differentiated wheat plants with varying degrees of resistance. The assay developed a useful tool for the quantification of the pathogen in the early stages of infection and may provide a significant contribution to a more efficient selection of wheat genotypes in breeding studies. In the present study, expression levels of PR proteins, phenylalanine ammonia-lyase, catalase, ascorbate peroxidase, and superoxide dismutase enzymes were upregulated in Anafarta (resistant) and Nenehatun (susceptible) cultivars at different post-infection time points, but more induced in the susceptible cultivar. The results showed considerable variation in the expression levels and timing of defense genes in both cultivars.

“…This criterion is measured by traits that determine the relationship of the “parasite-plant-host” pathosystem, such as colony growth rate, number of virulent races, sporulation intensity, etc. ( Sultana et al, 2018 ). According to Dontsova (2015) , the barley net blotch was found to infect wheat in recent years due to the arid climate of Southern Russia.…”
