The purpose of this study was to determine the fine-scale genetic structure of populations of the brown rot pathogen Monilinia fructicola within individual peach tree canopies to better understand within-tree plant pathogen diversity and to complement previous work on spatiotemporal development of brown rot disease at the canopy level. Across 3 years in a total of six trees, we monitored diseas...

Abstract Several Aureobasidium spp. strains isolated from wild environments during winter 2022 were characterized by sequence analysis of the internal transcribed spacer (ITS), translation elongation factor EF-1α gene (EF1), and part elongase (ELO). The variability in EF1 ELO loci are higher than ITS. All but one (UC14), identified as A. pullulans . To assess effectiveness biocontrol agents (BC...
