Abstract Infections caused by multidrug resistant bacteria represent a therapeutic challenge both in clinical settings and livestock production, but the prevalence of antibiotic resistance genes among species that colonize gastrointestinal tract ruminants is not well characterized. Here, we investigate resistome 435 ruminal microbial genomes silico confirm representative phenotypes vitro. We find high abundance encoding tetracycline evidence tet (W) gene under positive selective pressure....
Manipulating the rhizosphere microbial community through beneficial microorganism inoculation has gained interest in improving crop productivity and stress resistance. Synthetic communities, known as SynComs, mimic natural compositions while reducing number of components. However, achieving this goal requires a comprehensive understanding communities carefully selecting compatible microorganisms with colonization traits, which still pose challenges. In study, we employed multi-genome...
Bacteria of the genus Desulfovibrio belong to group Sulphate Reducing (SRB). SRB generate significant liabilities in petroleum industry, mainly due their ability microbiologically induce corrosion, biofilm formation and H
Cochliobolus heterostrophus is a dothideomycete that causes Southern Corn Leaf Blight disease. There are two races, race O and T differ by the absence (race O) presence T) of ~ 1.2-Mb DNA encoding genes responsible for production T-toxin, which makes much more virulent than O. The repetitive elements in fungal genomes considered to be an important source genetic variability between different species. A detailed analysis class I II TEs identified near complete genome sequence was performed....
A small (3.9 kb) plasmid (p518), conferring resistance to florfenicol (MIC >8 μg/mL) and chloramphenicol was isolated from an Actinobacillus pleuropneumoniae clinical isolate Southeastern Brazil. To date, this is the smallest a member of Pasteurellaceae. The complete nucleotide revealed unique gene arrangement compared previously reported plasmids found in other members In addition floR lysR gene, common various plasmids, p518 also encodes strA partial strB sequence. An origin replication...
Mobile genetic elements (MGEs) and antimicrobial resistance (AMR) drive important ecological relationships in microbial communities pathogen-host interaction. In this study, we investigated the resistome-associated mobilome 345 publicly available
Mycosphaerella fijiensis is a ascomycete that causes Black Sigatoka in bananas. Recently, the M. genome was sequenced. Repetitive sequences are ubiquitous components of fungal genomes. In most genomic analyses, repetitive associated with transposable elements (TEs). TEs dispersed DNA found host genome. These have ability to move from one location another within genome, and their insertion can cause wide spectrum mutations hosts. Some deleterious effects may be due ectopic recombination among...
Genetic diversity analysis of Pseudocercospora griseola DNA 27 P. isolates from Goiás, Minas Gerais, Espírito Santo, and Paraná States was extracted amplified using specific primers for ISSR.Using cluster analysis, genotypes were identified.The ISSR-PCR technique suitable assessing intraspecific variability griseola.The marker found to be highly sensitive genetic variation can aid in elucidating the structure population this plant pathogen as a support tool dry bean breeding programs.
The extensive genetic diversity of Ralstonia solanacearum , a serious soil-borne phytopathogen, has led to the concept that R. encompasses species complex [ (RSSC)]. Insertion sequences (ISs) are suggested play an important role in genome evolution this pathogen. Here, we identified and analysed transposable elements (TEs), ISs transposons, 106 RSSC genomes 15 spp. We mapped 10 259 IS complete 62 representative strains closely related A unique set 20 families was widespread across strains, 5...
Genetic variability in phytopathogens is one of the main problems encountered for effective plant disease control. This fact may be related to presence transposable elements (TEs), but little known about their role host genomes. Here, we performed most comprehensive analysis insertion sequences (ISs) and transposons (Tns) genomes important bacterial pathogens. A total 35 692 ISs 71 were identified 270 complete The level pathogen–host specialization was found a significant determinant element...
Endophytic fungi are microorganisms that inhabit internal plant tissues without causing apparent damage. During the infection process, both endophytic and phytopathogenic secrete proteins to resist or supplant plant's defense mechanisms. This study analyzed predicted secretomes of six species compared them with eight fungal different lifestyles: saprophytic, necrotrophic, hemibiotrophic, biotrophic. The sizes varied from 260 1640 proteins, have a wide diversity CAZymes, proteases, conserved...
Abstract Background ICEs are mobile genetic elements found integrated into bacterial chromosomes that can excise and be transferred to a new cell. They play an important role in horizontal gene transmission carry accessory genes may provide interesting phenotypes for the bacteria. Here, we seek research presence of 300 genomes phytopathogenic bacteria with greatest scientific economic impact. Results Seventy-eight (45 distinct elements) were identified characterized Agrobacterium tumefaciens...
It is claimed that one g of soil holds ten billion bacteria representing thousands distinct species. These play key roles in the regulation terrestrial carbon dynamics, nutrient cycles, and plant productivity. Despite overwhelming diversity bacteria, most bacterial species remain largely unknown. Here, we used an oligotrophic medium to isolate novel for positive interaction with soybean. Strictly 22 from soybean rhizosphere were selected. isolates encompass genera (Kosakonia, Microbacterium,...
