16S-23S RDNA: Polymorphisms and their use for detection and identification of Xylella fastidiosa strains
Strains of Xylella fastidiosa from several hosts (coffee, citrus, grape, almond, oleander, peach, plum, etc.) were characterized by analyzing the content of the nucleotide sequences of 16S- 23S rDN...
Analysis of 16S rRNA and mxaF genes revealing insights into Methylobacterium niche-specific plant association
The genus Methylobacterium comprises pink-pigmented facultative methylotrophic (PPFM) bacteria, known to be an important plant-associated bacterial group. Species of this group, described as plant-...
Anterior Foregut Microbiota of the Glassy-Winged Sharpshooter Explored Using Deep 16S rRNA Gene Sequencing from Individual Insects
The glassy-winged sharpshooter (GWSS) is an invasive insect species that transmits Xylella fastidiosa, the bacterium causing Pierce's disease of grapevine and other leaf scorch diseases. X. fastidi...
A Short Protocol for Gene Knockout and Complementation in Xylella fastidiosa Shows that One of the Type IV Pilin Paralogs (PD1926) Is Needed for Twitching while Another (PD1924) Affects Pilus Number and Location
Twitching motility is one of the major virulence factors of the plantpathogenic bacterium Xylella fastidiosa, and it is mediated by type IV pili (TFP) that are present at one of the cell poles. Gen...
Biofilm Formation by the Fish Pathogen Flavobacterium columnare: Development and Parameters Affecting Surface Attachment
Flavobacterium columnare is a bacterial fish pathogen that affects many freshwater species worldwide. The natural reservoir of this pathogen is unknown, but its resilience in closed aquaculture sys...
Biotechnological and Agronomic Potential of Endophytic Pink-Pigmented Methylotrophic Methylobacterium spp.
The genus Methylobacterium is composed of pink-pigmented facultative methylotrophic (PPFM) bacteria, which are able to synthesize carotenoids and grow on reduced organic compounds containing one ca...
Characterization and transcriptional analysis of an ECF sigma factor from Xanthomonas campestris pv. campestris
The genomic DNA segment encoding the rpoE gene and its flanking region was cloned from Xanthomonas campestris pv. campestris strain 11 (Xc11). The transcriptional start site of rpoE was located at ...
Characterization of N2O-producing Xanthomonas-like isolates from biofilters as Stenotrophomonas nitritireducens sp nov., Luteimonas mephitis gen. nov., sp nov and Pseudoxanthomonas broegbernensis gen. nov., sp nov.
A group of yellow-pigmented isolates from ammonia-supplied biofilters showed an unusual denitrification reaction. All strains reduced nitrite but not nitrate without production of nitrogen (N-2). T...
Characterizing the Native Codon Usages of a Genome: An Axis Projection Approach
Codon usage can provide insights into the nature of the genes in a genome. Genes that are "native" to a genome (have not been recently acquired by horizontal transfer) range in codon usage from a l...
Citrus plastid-related gene profiling based on expressed sequence tag analyses
Plastid-related sequences, derived from putative nuclear or plastome genes, were searched in a large collection of expressed sequence tags (ESTs) and genomic sequences from the Citrus Biotechnology...
De novo transcriptome assemblies of four xylem sap-feeding insects
Spittle bugs and sharpshooters are well-known xylem sap-feeding insects and vectors of the phytopathogenic bacterium Xylella fastidiosa (Wells), a causal agent of Pierce's disease of grapevines and...
Diversity of endophytic bacteria in Brazilian sugarcane
Endophytic bacteria live inside plant tissues without causing disease. Studies of endophytes in sugarcane have focused on the isolation of diazotrophic bacteria. We examined the diversity of endoph...
