Two bioactive cyclic dipeptides, cyclo(L-Pro-L-Tyr) and cyclo(D-Pro-L-Tyr), were isolated from the culture broth of Streptomyces sp. strain 22-4 and tested against three economically important plant pathogens, Xanthomonas axonopodis pv. citri, Ralstonia solanacearum and Clavibacter michiganensis. Both cyclic dipeptides were active against X. axonopodis pv. citri and R. Solanacearum with MIC of ...
DNA macroarrays of 279 genes of Xanthomonas axonopodis pv. citri potentially associated with pathogenicity and virulence were used to compare the transcriptional alterations of this bacterium in response to two synthetic media. Data analysis indicated that 31 genes were up-regulated by synthetic medium XVM2, while only 7 genes were repressed. The results suggest that XVM2 could be used as an in...
Recent studies have demonstrated that an appropriate light environment is required for the establishment of efficient vegetal resistance responses in several plant-pathogen interactions. The photoreceptors implicated in such responses are mainly those belonging to the phytochrome family. Data obtained from bacterial genome sequences revealed the presence of photosensory proteins of the BLUF (Bl...
Xanthomonas axonopodis pv. citri is a phytopathogen bacterium that causes severe citrus canker disease. Similar to other phytopathogens, after infection by this bacterium, plants trigger a defense mechanism that produces reactive oxygen species. Ferredoxin-NADP(+) reductases (FNRs) are redox flavoenzymes that participate in several metabolic functions, including the response to reactive oxygen ...
We have solved the structure of ferredoxin-NADP(H) reductase, FPR, from the plant pathogen Xanthomonas axonopodis pv. citri, responsible for citrus canker, at a resolution of 1.5 Å. This structure reveals differences in the mobility of specific loops when compared to other FPRs, probably unrelated to the hydride transfer process, which contributes to explaining the structural and functional div...
Xanthomonas axonopodis pv. citri is a phytopathogenic bacterium responsible for citrus canker, a serious disease which causes severe losses in citriculture around the world. In this study we report the differential expression of X. axonopodis pv. citri in response to specific treatments by using Representational Difference Analysis of cDNA (cDNA RDA). cDNAs from X. axonopodis pv. citri cultured...
abstract citrus bacterial canker disease caused by xanthomonas axonopodis pv. citri is one of the most important diseases of citrus in south of iran. in this research, the samples of bacterial flora of citrus leaves were collected from various citrus growing areas of hormozgan, jiroft and mazandaran.the epiphytic bacteria were isolated from those leaves during 2000 and 2001 years. from 453 isol...
الگوی پروتئین الکتروفورز شده 21 استرین xanthomonas axonopodis pv. citri جدا شده از مرکبات دو استان هرمزگان و کرمان به همراه استرین های استاندارد نماینده x. a. pv. citri و x.a. pv. aurantifoli توسط نرم افزار gel compar version 4.2 با 246 استرین از گونه های:x. a. pv. citri, x. a. pv. glycins, x. a. pv. manihotis, x. campestris pv. campestris, x. a. pv. phaseoli, x. cassavae, x. vesicatoria, x. c....
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 protein Clp from Xanthomonas axonopodis pv. citri regulates pathogenesis and is a member of the CRP (cyclic AMP receptor protein) superfamily. We show that unlike the DNA-binding activity of other members of this family, the DNA-binding activity of Clp is allosterically inhibited by its effector and that cyclic di-GMP serves as that effector at physiological concentrations.
