Characterization of aapP and nopP genes related to the biological nitrogen fixation efficiency with soybean in contrasting strains of Bradyrhizobium japonicum
Soybean (Glycine max) is considered one of the most economically important agricultural crops in Brazil. Due to the high protein content of its grains, this crop demands a greater amount of nitrogen (N) for production. In general, for soybean, nitrogen fertilization costs through chemical fertilizers are considered high. However, the biological nitrogen fixation (BN.. Read More»

Screening of basidiomycetes in submerged cultivation based on antioxidant activity
Submerged cultivation of medicinal basidiomycetes is a reproducible and efficient method of producing mycelia and metabolites. The antioxidant activity indicates its medicinal properties and is an important tool for basidiomycete screening. In this study, we analyzed the production of mycelial biomass and exopolysaccharides and the antioxidant activity of basidiomycete strains in submerged cult.. Read More»

Genomic variability of Pantoea ananatis in maize white spot lesions assessed by AFLP markers
Measures to control maize white spot (MWS) caused by Pantoea ananatis are preferentially based on resistant cultivars. A lack of knowledge on the genetic variability of pathogens could interfere with the development and utilization of controlling strategies in this pathosystem. The main goals of this study were to investigate the genetic variability of 90 P. ananati.. Read More»

Characterization of the inaA gene and expression of ice nucleation phenotype in Pantoea ananatis isolates from Maize White Spot disease
Maize White Spot (MWS), a foliar disease caused by Pantoea ananatis, could cause up to 60% yield loss. Some strains of P. ananatis harboring the ice nucleation gene inaA catalyze the formation of ice nuclei, causing tissue damage at temperatures slightly below freezing. Little is known about the relationship between the presence of the ina gene in this maize pathogen and its expression during t.. Read More»

Genetic diversity and pectinolytic activity of epiphytic yeasts from grape carposphere
The genetic diversity of epiphytic yeasts from grape carposphere is susceptible to environmental variations that determine the predominant carposphere microbiota. Understanding the diversity of yeasts that inhabit grape carposphere in different environments and their pectinolytic activity is a way to understand the biotechnological potential that surrounds us and he..
