Draft genome sequences of two biocontrol agents isolated from the maize phyllosphere strain EM-A7 and strain EM-A8.

In the present study, the genomes of EM-A7 and EM-A8 were sequenced and annotated. The Illumina sequencing platform (NovaSeq PE150) was used to sequence the genomic DNA. There were 6 277 054 raw reads for EM-A7, with a Q20 of 97.

Physiological Effects of Microbial Biocontrol Agents in the Maize Phyllosphere.

In a world with constant population growth, and in the context of climate change, the need to supply the demand of safe crops has stimulated an interest in ecological products that can increase agricultural productivity. This implies the use of beneficial organisms and natural products to improve crop performance and control pests and diseases, replacing chemical compounds that can affect the environment and human health. Microbial biological control agents (MBCAs) interact with pathogens directly or by inducing a physiological state of resistance in the plant.

studies of biofilm-forming strains, biocontrol agents isolated from the maize phyllosphere.

We aimed to assess how biofilm formation by three isolates was affected by changes in temperature, water potential, growth media, time, and the combinations between these factors. The strains had been selected as potential biological control agents (BCAs) in earlier studies, and they were identified as and spp. through 16 rRNA sequencing and MALDI-TOF MS.

Efficacy of epiphytic bacteria to prevent northern leaf blight caused by Exserohilum turcicum in maize.

Eight potential biological control agents (BCAs) were evaluated in planta in order to assess their effectiveness in reducing disease severity of northern leaf blight caused by Exserohilum turcicum. The assay was carried out in greenhouse. Twenty-six-day-old plants, V4 phenological stage, were inoculated with antagonists by foliar spray.

Selection of potential biological control of Exserohilum turcicum with epiphytic microorganisms from maize.

The aims of this study were to select microbial isolates from phyllosphere of maize and to examine their antagonistic activity against Exserohilum turcicum. Selection was performed through the ability of isolates to compete with the pathogen using an index of dominance and to affect growth parameters of E. turcicum.

Impact of osmotic/matric stress and heat shock on environmental tolerance induction of bacterial biocontrol agents against Fusarium verticillioides.

Bacillus amyloliquefaciens and Microbacterium oleovorans reduced the Fusarium verticillioides count and significantly decreased fumonisin B(1) and B(2) levels in maize grains. The aim of this study was to determine the effect of water stress tolerance and heat shock survival upon cells of the biocontrol agents B. amyloliquefaciens and M.
