Originally named following its identification as a cause of soft rot in onions, Burkholderia cepacia has also been known as Pseudomonas multivorans and Pseudomonas kingae [1,2], and until most recently, as Pseudomonas cepacia [3]. A proposal for the transfer of 7 species of the genus Pseudomonas RNA Homology group II to a new genus Burkholderia with the type-species Burkholderia cepacia has bee...

CRISPR (clustered regularly interspaced short palindromic repeats) arrays and Cas (CRISPR-associated) proteins confer acquired resistance against mobile genetic elements in a wide range of bacteria and archaea. The phytopathogen Pectobacterium atrosepticum SCRI1043 encodes a single subtype I-F CRISPR system, which is composed of three CRISPR arrays and the cas operon encoding Cas1, Cas3 (a Cas2...

The oligopeptide-binding protein, OppA, ushers oligopeptide substrates to the membrane-associated oligopeptide permease (Opp), a multi-component ABC-type transporter involved in the uptake of oligopeptides by several bacterial species. In the present study, we report a structural model and an oligopeptide docking analysis of the OppA protein expressed by Xanthomonas axonopodis pv. citri (X. cit...

The integration and excision of various filamentous phage genomes into and out of their host chromosomes occurs by site-specific recombination. The mechanisms proposed for these events include reactions mediated by phage-encoded recombinases and host recombination systems. Site-specific integration of filamentous phages plays a vital role in a variety of biological functions of the host, such a...

Bacterial wilt phytopathogen Ralstonia solanacearum is a serious soil-borne disease that attacks several economically important plants worldwide, including Brassicaceae. Previous studies indicate that recognition of avirulence (Avr)-effector PopP2 by resistance (R) protein, RRS1-R, and physical interaction between RRS1-R and PopP2 in the nucleus are required for resistance. Of late, we showed t...

Plant growth-promoting bacterial endophytes (PGPBEs) produce volatile and diffusible compounds that inhibit phytopathogens (Santoyo et al., 2016) [1]. A recent work by Rojas-Solis and colleagues [2] demonstrated the antifungal effect of volatile organic compounds exerted by the Pseudomonas stutzeri E25 and Stenotrophomonas maltophilia CR71 endophytes, highlighting the production of sulfur-conta...

To carry out effective plant protection measures, it is necessary to take into account all the factors affecting quality of crop. The aim our research was study degree development leaf diseases winter wheat and rate infestation crops, depending on tillage method. studies were carried in 2019-2020 at experimental plots “Kuban educational farm” Krasnodar. For research, four with Steppe variety so...

Colletotrichum gloeosporioides is the most prevalent phytopathogen, causing anthracnose disease that severely affects production of various fruit trees, including walnut and jujube. In this study, volatile organic compounds (VOCs) from Bacillus velezensis CE 100 disrupted cell membrane integrity C. reduced spore germination by 36.4% mycelial growth 20.0% at a bacterial broth concentration 10%, ...
