Identification of Fungal Species Associated with Crown and Root Rots of Wheat and Evaluation of Plant Reactions to the Pathogens in North Dakota.

Common root rot (CRR) and crown rot (CR), caused by and species, respectively, can cause significant yield losses in cereal crops. To assess the prevalence, incidence, and severity of these diseases in North Dakota, wheat samples were collected from spring wheat fields across the state in 2012, 2013, and 2014. Based on subcrown internode symptoms, a greater incidence and severity of CRR was observed in 2012 (warm and dry year) than in 2013 and 2014.

Rapid Detection of in Sugar Beet and Mutations Associated with Fungicide Resistance Using LAMP or Probe-Based qPCR.

Cercospora leaf spot (CLS), caused by the fungal pathogen , is the most destructive disease of sugar beet worldwide. Although growing CLS-tolerant varieties is helpful, disease management currently requires timely application of fungicides. However, overreliance on fungicides has led to the emergence of fungicide resistance in many populations, resulting in multiple epidemics in recent years.

Transcriptome-wide association study identifies putative elicitors/suppressor of Puccinia graminis f. sp. tritici that modulate barley rpg4-mediated stem rust resistance.

Background: Stem rust is an economically important disease of wheat and barley. However, studies to gain insight into the molecular basis of these host-pathogen interactions have primarily focused on wheat because of its importance in human sustenance. This is the first extensive study utilizing a transcriptome-wide association mapping approach to identify candidate Puccinia graminis f.

Coordinated and independent functions of velvet-complex genes in fungal development and virulence of the fungal cereal pathogen Cochliobolus sativus.

LaeA and velvet proteins regulate fungal development and secondary metabolism through formation of multimeric complexes in many fungal species, but their functions in the cereal fungal pathogen Cochliobolus sativus are not well understood. In this study, four velvet complex genes (CsLaeA, CsVeA, CsVelB, and CsVelC) in C. sativus were identified and characterized using knockout mutants generated for each of the genes.
