Peanut smut caused by Thecaphora frezii is a severe fungal disease currently endemic to Argentina and Brazil. The identification of resistant germplasm crucial in view the potential risk global spread. In recent study, we reported new sources resistance demonstrated its introgression into elite peanut cultivars. Here, revisited one these (line I0322) verify presence U.S. collection identify sin...

ABSTRACT Genetic resistance is the most efficient tool in crop disease management. Peanut smut currently one of important peanut diseases, with its incidence increasing terms both damage level and area covered. The aim this study was to assess response different genotypes obtained by Facultad de Agronomía y Veterinaria Universidad Nacional Río Cuarto (Argentina) their yield. During 2016/17, 201...

We analyzed the structure of foliicolous lichen communities in northernmost lowland forest Neotropics, Los Tuxtlas Tropical Biology Station Veracruz, Mexico, and its dependence on phorophyte microclimate. Along a 420-m long transect with 15 equidistant sampling points, within 10 m radius each point, we sampled total 137 phorophytes 411 leaves. The represented 13 species, diverse leaf traits reg...

Peanuts can be affected by the presence of pathogenic microorganisms. The fungus Thecaphora frezii (T. frezii), which belongs to taxonomic class Ustilaginomycetes, is causal agent disease known as “peanut smut”. life cycle this includes three stages, namely teliospores, basidiospores and hyphae. In hyphae stage, infection occurs in peanut plant, requires involvement some enzymes secreted fungus...
