bacterial leaf streak (bls) caused by xanthomonas translucens pv. cerealis (xtc) is an important disease of wheat (triticum aestivum l.) worldwide. the management methods presently in practice are insufficient to meet current safety and/or efficacy standards. therefore, use of resistant genotypes is the best approach to manage bls. the present study was undertaken to identify possible sources o...
The phylogenetic relationships of all validly described species of the genus Xanthomonas and the type strain of Stenotrophomonas maltophilia were analyzed by sequencing and comparing 16S ribosomal DNAs (rDNAs). The two genera exhibited a mean sequence similarity value of 96.6%, corresponding to differences at 50 nucleotide positions on average. The species of the genus Xanthomonas exhibited rel...
ABSTRACT In 1980, over 90% of all plant-pathogenic pseudomonads and xanthomonads were lumped into Pseudomonas syringae and Xanthomonas campestris, respectively, as pathovars. The term "pathovar" was created to preserve the name of plant pathogens, but has no official standing in nomenclature. Proposals to elevate and rename several pathovars of the genera Pseudomonas and Xanthomonas to the rank...
The barley genes HvLtp4.2 and HvLtp4.3 both encode the lipid transfer protein LTP4 and are less than 1 kb apart in tail-to-tail orientation. They differ in their non-coding regions from each other and from the gene corresponding to a previously reported Ltp4 cDNA (now Ltp4.1). Southern blot analysis indicated the existence of three or more Ltp4 genes per haploid genome and showed considerable p...
Toxin-antitoxin (TA) systems are ubiquitous bacterial systems that may function in genome maintenance and metabolic stress management, but are also thought to play a role in virulence by helping pathogens survive stress. We previously demonstrated that the Xanthomonas oryzae pv. oryzicola protein AvrRxo1 is a type III-secreted virulence factor that has structural similarities to the zeta family...
