Article Synopsis
  • Frogeye leaf spot, traditionally a southern disease, is increasingly affecting soybeans in North Central USA, prompting a study on its population structure in Indiana.
  • Researchers identified 49 multi-locus genotypes (MLGs) from 234 isolates, grouping them into three clusters and confirming a balanced distribution of mating types across most counties.
  • The analysis revealed the dominance of one genotype (MLG1), associated with QoI-resistant isolates, and indicated significant linkage disequilibrium in the population, with implications for understanding the disease's spread and management.

Soybean sudden death syndrome (SDS) is a destructive disease that causes substantial yield losses in South and North America. Whereas four species were identified as the causal agents, is the primary SDS-causing pathogen in North America and it also contributes substantially to SDS in Argentina. In this study, we comparatively analyzed genome assemblies of four strains and identified 29 informative microsatellite markers.

Ceratocystis fimbriata is an important pathogen that causes wilt in several plant species. Despite the importance of this pathogen, knowledge about its karyotypic polymorphism and genomic architecture is limited. The main objective of this study was to investigate the karyotype of isolates of the C.

Anthracnose, caused by Colletotrichum lindemuthianum, is a disease affecting the common bean plant, Phaseolus vulgaris. To establish infection, the phytopathogen must survive the toxic compounds (phytoanticipins and phytoalexins) that are produced by the plant as a defense mechanism. To study the detoxification and efflux mechanisms in C.

Aim: To identify and analyse genes that encode pectinases in the genome of the fungus Colletotrichum lindemuthianum, evaluate the expression of these genes, and compare putative pectinases found in C. lindemuthianum with pectinases produced by other fungi and oomycetes with different lifestyles.

Methods And Results: Genes encoding pectinases in the genome of C.

The Núcleo de Estudos em Microbiologia Agrícola (NEMA) is an academic-scientific group created by graduate students in the Post Graduate in Agricultural Microbiology in the Department of Microbiology at Universidade Federal de Viçosa, Brazil. NEMA's purposes include promoting and sharing research and knowledge on microbiology in different fields of application. Here, we will comment on our experience in organizing the Summer School on Microbiology and teaching microbiology to undergraduate students during the program.

A survey to investigate the occurrence of cassava anthracnose disease (CAD) and distribution of spp. in cassava plantations in different eco-zones of the Reconcavo Region in Bahia, Brazil, investigated during the rainy season of 2014. A total of 50 cassava fields distributed among 18 municipalities were visited and intensity of anthracnose evaluated.

The genus Colletotrichum comprises species with different lifestyles but is mainly known for phytopathogenic species that infect crops of agronomic relevance causing considerable losses. The fungi of the genus Colletotrichum are distributed in species complexes and within each complex some species have particularities regarding their lifestyle. The most commonly found and described lifestyles in Colletotrichum are endophytic and hemibiotrophic phytopathogenic.
