Abstract In the bacterial spot of tomato disease complex, Xanthomonas euvesicatoria pv. perforans ( Xep ) is known to outcompete X. Xee ). The result, over time in production systems where both pathogens are present, anticipated displacement by . this study, we characterized population recovered strains from grower fields response a outbreak east and central Oklahoma 2018 2019. Tomato pepper sampled earlier years were included provide additional context. Phenotypic genome-based analyses showed marked differences race species composition strains. All pre-2018 (2001-2014) T3, except one T4 strain. consisted T1 while 2019 same locations exclusively form cluster with 2014 strain on phylogenetic tree, suggesting population. Only an expanded host range pepper. also variable copper sensitivity effector content. We additionally non-bacterial xanthomonads, which belongs new species, oklahomensis sp. nov. These results contributes novel insights understanding genomic heterogeneity seasonal flux between competing genotypes during outbreaks can be considered when developing management strategies.

Abstract The world has arguably identified both output and population growth over time. Thus, the demand for agricultural commodities such as biofuels prominent challenges associated with sustainable land use, water, food development all play a significant role in process, countries strive to achieve use of different approaches, convergence per capita, energy water availability, production, more safely ecologically. Therefore, this study is led by Access Neo-Malthusian theories investigate effects food, energy, security sustainability achieving goals using annual data covering 1980 2020 estimate asymmetric autoregressive distributive lag approach. Accordingly, results revealed that positive changes on differ significantly from those negative changes. A 1% change supply development, or industrial value addition impact development; however, carbon emission, growth, depletion natural resources substantial adverse economic short run long Nigeria. findings also restoring equilibrium 2030 SDGs requires 16.2% each year. recommends adopting innovative systems control help manage available human productive sectors increase value-added renewable production
