Xanthomonas campestris pv. glycines: Pathogenicity genes, races, and soybean yield
Sixteen nonpathogenic mutants of X. campestris pv. glycines strain 8ra were generated with N-methyl-N-nitro-N$\sp\prime$-nitrosoguanidine to identify and characterize pathogenicity genes of the bacterium. A rapid bioassay technique using soybean cotyledons was developed to evaluate the large number …

Structural and functional characterization of a Xanthomonas Type III effector
Rice bacterial leaf streak disease caused by Xanthomonas oryzae pv. oryzicola (Xoc) is one of the most important rice bacterial diseases. Xanthomonas type III effector gene avrRxo1 is conserved in diverse Xoc strains and its homologues have been identified from several other gram-negative bacteria …

Pantoea and Xanthomonas species associated with blight and die-back of Eucalyptus
… important plants and trees. Since both Xanthomonas and Pantoea species are becoming increasing important as emerging bacterial pathogens, their rapid and accurate identification is crucially important. Little is known about bacterial pathogens on forestry trees since the most prominent …

Clarification of the xanthan biosynthesis mechanism in Xanthomonas campestris pv. campestris B100 by mass spectrometry-based proteome analysis
… In the first project, the proteome profiling of Xanthomonas campestris pv. campestris over the time of cultivation was considered. The consumption of nutrition and the amount of synthesized xanthan were particularly interesting. The reference database indicates that 2416 proteins were detected …

Characteristics of biological control agents and their antagonism against rice pathogens and pests
… I tested their potential activity against Xanthomonas oryzae pv. oryzae, Meloidogyne graminicola and Nilaparvata lugens. The results of these experiments (Chapter 2) showed that some beneficial bacterial strains demonstrated either their adverse effects on the abovementioned biotic …

Cyclic di-GMP signalling and the regulation of virulence, biofilm formation and epiphytic fitness in the phytopathogen <i>Xanthomonas campestris</i>
The full virulence of Xan<i>thomonas campestris</i> pathovar c<i>ampestris</i> (<i>Xcc</i>) for its host plant is dependent on many different factors (Chan and Goodwin, 1999). A pivotal role is played by the second messenger cyclic di-GMP. C-di-GMP is essential for successful infection of the host …
