Xanthomonas albilineans causes leaf scald, a lethal disease of sugarcane. Compared to other species of Xanthomonas, X. albilineans exhibits distinctive pathogenic mechanisms, ecology and taxonomy. Its genome, which has experienced significant erosion, has unique genomic features. It lacks two loci required for pathogenicity in other plant pathogenic species of Xanthomonas: the xanthan gum biosy...
Chlorpyrifos (CP) is one of the most widely used organophosphate pesticides in agriculture worldwide, but its extensive use has led to the contamination of various soil and water systems. Microbial bioremediation is considered to be one of the most viable options for the removal of CP from the environment; however, little is known about the soil bacterial diversity that degrade CP. Sequential s...
In this study we developed an algorithm to screen for all exact molecular signatures of the quarantine pathogen Xanthomonas axonopodis pv. phaseoli (Xap), based on available data of the presence or absence of virulence-associated genes. The simultaneous presence of genes avrBsT and xopL is specific to Xap. Therefore we developed a multiplex PCR assay targeting avrBsT and xopL for the molecular ...
الگوی های مولکولی مرتبط با میکروب (microbe-associated molecular patterns-mamps) نقش کلیدی در فعال سازی پاسخ های ایمنی ذاتی (innate immunity) در جانوران و به صورت مشابهی، به عنوان انگیزنده های (elicitors) پاسخ های دفاعی در گیاهان دارند. با وجود این، بررسی های زیادی دربارة اهمیت واقعی آن ها در مقاومت گیاه نسبت به بیمارگرها وجود ندارد. در این تحقیق اثر مشتقات فاکتور نسخه برداری ef-tu و فلاژلین به ...
An annotated high-quality draft genome sequence for Xanthomonas campestris pv. campestris race 1 strain Xca5 (originally described as X. campestris pv. armoraciae), the causal agent of black rot on Brassicaceae plants, has been determined. This genome sequence is a valuable resource for comparative genomics within the campestris pathovar.
A new antibiotic termed zelkovamycin was isolated from the fermentation broth of Streptomyces sp. K96-0670 by solvent extraction, ODS column chromatography and preparative HPLC. Zelkovamycin showed antibacterial activity against Xanthomonas oryzae, Acholeplasma laidlawii, Pyricularia oryzae and Staphylococcus aureus.
Banana Xanthomonas wilt is a newly emerging disease that is currently threatening the livelihoods of millions of farmers in East Africa. The causative agent is Xanthomonas campestris pathovar musacearum (Xcm), but previous work suggests that this pathogen is much more closely related to species Xanthomonas vasicola than to X. campestris. We have generated draft genome sequences for a banana-pat...
Ten strains of Xanthomonas axonopodis pv. glycines, the causal agent of bacterial pustule of soybean, which were isolated from various soybean growing regions of Thailand, produced an extracellular diffusible factor (DSF) related to a well-characterized quorum sensing molecule produced by other Xanthomonas spp. Genomic DNA of the 10 strains of X. axonopodis pv. glycines contained rpfF, a gene e...
The calmodulin-dependent adenylate cyclase domain (Cya) of the Bordetella pertussis cyclolysin was used as a reporter protein to study the direct translocation of the Xanthomonas effector protein, AvrBs2, into the plant host cell. Adenylate cyclase activity (production of cAMP) depends on the presence of eukaryotic plant calmodulin and is only active after translocation from the prokaryotic cel...
Ralstonia solanacearum GMI1000 is a gram-negative plant pathogen which contains an hrp gene cluster which codes for a type III protein secretion system (TTSS). We identified two novel Hrp-secreted proteins, called PopF1 and PopF2, which display similarity to one another and to putative TTSS translocators, HrpF and NopX, from Xanthomonas spp. and rhizobia, respectively. They also show similariti...
