“…Notably, the latter represents an improvement of the former with higher statistical power. The ability of BratNextGen to reveal ancestral recombination has been applied in studies related to Streptomyces species [ 79 ], antibiotic-resistant Staphylococcus aureus strains [ 80 ], and differentiated Xylella fastidiosa isolates [ 81 ].…”

The role of genetic exchanges, i.e., homologous recombination (HR) and horizontal gene transfer (HGT), in bacteria cannot be overestimated for it is a pivotal mechanism leading to their evolution and adaptation, thus, tracking the signs of recombination and HGT events is importance both for fundamental and applied science. To date, dozens of bioinformatics tools for revealing recombination signals are available, however, their pros and cons as well as the spectra of solvable tasks have not yet been systematically reviewed. Moreover, there are two major groups of software. One aims to infer evidence of HR, while the other only deals with horizontal gene transfer (HGT). However, despite seemingly different goals, all the methods use similar algorithmic approaches, and the processes are interconnected in terms of genomic evolution influencing each other. In this review, we propose a classification of novel instruments for both HR and HGT detection based on the genomic consequences of recombination. In this context, we summarize available methodologies paying particular attention to the type of traceable events for which a certain program has been designed.

Progression of Xylella fastidiosa Infection in Grapevines Under Field Conditions

et al. 2023

The pathogen Xylella fastidiosa subspecies fastidiosa has circulated through California’s vineyards since its introduction from Central America in the 1800s. This pathogen is responsible for a bacterial disease called Pierce’s disease of grapevine (PD). With no known cure, PD has had devastating effects on some vineyards. Important factors that impact disease severity and persistence include: the presence of insect vectors, grapevine cultivar, management, ecology, and winter temperatures. Removal of infected vines is critical for reducing pathogen spread, but relies on accurate and rapid pathogen detection. In this study, we foster a greater understanding of disease symptom emergence by way of a three-year field inoculation project in Napa Valley. Although PD emergence and symptom progression have been studied in greenhouse and experimental plots, there is a large knowledge gap in quantifying disease progression under commercial conditions. After inoculating 80 mature Vitis vinifera vines in April, 2017, bacterial populations and six symptom types were measured at four locations within each plant, throughout the subsequent 3 growing seasons. The main foci of the project were understanding X. fastidiosa movement through the plants, infection, overwinter curing, and symptom development. We observed greater winter recovery than expected, and shriveled grape clusters proved to be a more reliable early indication of infection than other more commonly used symptoms. Although there were differences among wine grape cultivars, this work suggests that disease progression in the field may not fit the paradigm of predominant leaf scorch and low recovery rates as neatly as has been previously believed.
