The gram-negative plant-pathogenic bacterium Xanthomonas campestris pv. vesicatoria is the causative agent of bacterial spot disease in pepper and tomato plants, which leads to economically important yield losses. This pathosystem has become a well-established model for studying bacterial infection strategies. Here, we present the whole-genome sequence of the pepper-pathogenic Xanthomonas campe...
Citrus bacterial canker caused by Xanthomonas axonopodis pv. citri is a serious disease that impacts citrus production worldwide, and X. axonopodis pv. citri is listed as a quarantine pest in certain countries. Biofilm formation is important for the successful development of a pathogenic relationship between various bacteria and their host(s). To understand the mechanisms of biofilm formation b...
The study of small heat shock proteins in plant-pathogen interactions is a subject that has to be further investigated. While Hsp70 and Hsp90 participate in the defense response, the role of this small Hsps remains elusive. In this work we analyzed the expression of small Hsps in citrus canker and the bacterial spot of pepper as well as in the incompatible interactions of the bacterial pathogen...
The location of lipopolysaccharides produced by Xanthomonas axonopodis pv. manihotis during pathogenesis on cassava (Manihot esculenta) was determined by fluorescence and electron microscopy immunolabeling with monoclonal antibodies. During the early stages of infection, pathogen lipopolysaccharides were detected on the outer surface of the bacterial envelope and in areas of the plant middle la...
A semi-selective agar medium was developed for detection of Xanthomonas axonopodis pv. malvacearum (Xam) in cotton (Gossypium hirsutum) seed. The basic medium was peptone-sucrose-agar (PSA). Criteria for the semi-selective medium were the typical colony characters of Xam and its pathogenicity on cotton. Several systemic fungicides and antibiotics in different concentrations were tested alone or...
Featured on this issue's front and back covers, we have "Mast Cell Degranulation in Response to Rho Activating Drugs" created by Juliette Eshleman "Galaxies of Glia Interface with Technology" Matthew Birtle. Other featured images include "Astrocytes: the stars brain" Katherine Souter, "Morphological changes microglia upon sensing environment" Kira Sviderskaia, "The Solar Farming Revolution: Agr...
Strains of the plant-pathogenic bacterium Xanthomonas axonopodis pv. citri are differentiated into two groups with respect to aggressiveness (normal and weak) on Citrus grandis cultivars but not on other Citrus species such as Citrus sinensis. Random mutagenesis using the transposon Tn5 in X. axonopodis pv. citri strain KC21, which showed weak aggressiveness on a C. grandis cultivar, was used t...
Xanthomonas bacteria are known phytopathogens difficult to control in the field, which cause great losses many economically important crops. Genomic islands fragments acquired by horizontal transference that for evolution and adaptation diverse ecological niches. Virulence pathogenicity (PAIs) enhance molecular mechanisms related host adaptation. In this work, we have analyzed 81 genomes belong...
Culture filtrates of six different edible mushroom species were screened for antimicrobial activity against tomato wilt bacteria Ralstonia solanacearum B3. Hericium erinaceus, Lentinula edodes (Sanjo 701), Grifola frondosa, and Hypsizygus marmoreus showed antibacterial activity against the bacteria. Water, n-butanol, and ethyl acetate extracts of spent mushroom substrate (SMS) of H. erinaceus e...
