Occurrence of Yam Mosaic Virus and Yam Mild Mosaic Virus on spp. Germplasm Collection in Cuba-Epidemiology of Associated Diseases.

Potyvirus diseases are one of the main challenges facing the production of yam ( spp.). The objective of this study was to identify the potyviruses present in the spp.

An Unwanted Association: The Threat to Papaya Crops by a Novel Potexvirus in Northwest Argentina.

An emerging virus isolated from papaya () crops in northwestern (NW) Argentina was sequenced and characterized using next-generation sequencing. The resulting genome is 6667-nt long and encodes five open reading frames in an arrangement typical of other potexviruses. This virus appears to be a novel member within the genus .

Performance, Rumen Microbial Community and Immune Status of Goat Kids Fed Post-weaning as Affected by Prenatal and Early Life Nutritional Interventions.

represents a local protein source in tropical ruminant diets. However, its full exploitation is impaired by mimosine, unless it is degraded by the rumen microbial community. Recently, the ruminal bacterial communities of newborns were persistently modified through prenatal or postnatal dietary interventions.

Diversity and abundance of Beauveria bassiana in soils, stink bugs and plant tissues of common bean from organic and conventional fields.

The aim of this study was to evaluate the natural occurrence of Beauveria spp. in soil, from infections in the stink bug Piezodorus guildinii, an important pest of common bean (Phaseolus vulgaris) and as endophytes in bean plant tissue. Twelve conventional and 12 organic common bean fields in the Villa Clara province, Cuba were sampled from September 2014 to April 2015.

Sugarcane genes differentially expressed in response to Puccinia melanocephala infection: identification and transcript profiling.

Brown rust caused by the fungus Puccinia melanocephala is a major disease of sugarcane (Saccharum spp.). A sugarcane mutant, obtained by chemical mutagenesis of the susceptible variety B4362, showed a post-haustorial hypersensitive response (HR)-mediated resistance to the pathogen and was used to identify genes differentially expressed in response to P.

Analysis of expressed sequence tags derived from a compatible Mycosphaerella fijiensis-banana interaction.

Mycosphaerella fijiensis, a hemibiotrophic fungus, is the causal agent of black leaf streak disease, the most serious foliar disease of bananas and plantains. To analyze the compatible interaction of M. fijiensis with Musa spp.

An efficient method for the extraction of high-quality fungal total RNA to study the Mycosphaerella fijiensis-Musa spp. Interaction.

Efficient RNA isolation is a prerequisite for gene expression studies and it has an increasingly important role in the study of plant-fungal pathogen interactions. However, RNA isolation is difficult in filamentous fungi. These organisms are notorious for their rigid cell walls and the presence of high levels of carbohydrates, excreted from the fungal cells during submerged growth, which interferes with the extraction procedures.
