Origin and domestication of the fungal wheat pathogen Mycosphaerella graminicola via sympatric speciation.
The Fertile Crescent represents the center of origin and earliest known place of domestication for many cereal crops. During the transition from wild grasses to domesticated cereals, many host-specialized pathogen species are thought to have emerged. A sister population of the wheat-adapted pathogen Mycosphaerella graminicola was identified on wild grasses collected in northwest Iran. Isolates ...
متن کاملDefining the Predicted Protein Secretome of the Fungal Wheat Leaf Pathogen Mycosphaerella graminicola
The Dothideomycete fungus Mycosphaerella graminicola is the causal agent of Septoria tritici blotch, a devastating disease of wheat leaves that causes dramatic decreases in yield. Infection involves an initial extended period of symptomless intercellular colonisation prior to the development of visible necrotic disease lesions. Previous functional genomics and gene expression profiling studies ...
متن کاملstudy on mating types and sensitivity to strobilurin fungicide in fungal wheat pathogen mycosphaerella graminicola
mycosphaerella graminicola, the causal agent of septoria tritici blotch (stb), is a widespread and significant pathogen of wheat. to determine mating types, 89 isolates were collected randomly from wheat fields of khuzestan, east azerbaijan, ardebil, kermanshah and golestan provinces of iran, during 2006-7. dna was extracted based on standard protocols. multiplex pcr was conducted using two pai...
متن کاملRapidly Evolving Genes Are Key Players in Host Specialization and Virulence of the Fungal Wheat Pathogen Zymoseptoria tritici (Mycosphaerella graminicola)
The speciation of pathogens can be driven by divergent host specialization. Specialization to a new host is possible via the acquisition of advantageous mutations fixed by positive selection. Comparative genome analyses of closely related species allows for the identification of such key substitutions via inference of genome-wide signatures of positive selection. We previously used a comparativ...
متن کاملFinished Genome of the Fungal Wheat Pathogen Mycosphaerella graminicola Reveals Dispensome Structure, Chromosome Plasticity, and Stealth Pathogenesis
The plant-pathogenic fungus Mycosphaerella graminicola (asexual stage: Septoria tritici) causes septoria tritici blotch, a disease that greatly reduces the yield and quality of wheat. This disease is economically important in most wheat-growing areas worldwide and threatens global food production. Control of the disease has been hampered by a limited understanding of the genetic and biochemical...
