Title:The molecular genetics of virulence of Xanthomonas campestris[1]Authors: James W.Y.F. Chan, Paul H. Goodwin Publication: Biotechnology Advances 17 (1999) 489–508 File: 1-s2.0-S0734975099000257-main.pdfDownload 1-s2.0-S0734975099000257-main.pdf This particular source is a research review paper that summarizes findings from a significant amount of articles to focus primarily on the molecular genetics that are responsible for the pathogenicity and virulence that impacts plants. It details specific gene regulation, enzymes, surface compounds, polysaccharides, etc. that are involved in the plant-bacterium interactions, which can be characterized as compatible or incompatible. This is very valuable information on the subject of Xanthomonas campestris because this bacterium is commonly known for its disease-causing impact on plants, and that is mentioned in the current page without detail. With that in mind, I plan to use this source to incorporate information and greater detail regarding the plant-bacterium interactions that lead to lethal bacterial diseases, like black rot in cruciferous plants, for example because this is a very important aspect of Xanthomonas campestris. In doing this, I think that I will most likely add a new section (in addition to the citation) and add some brief information in the lead section.
Title:Cruciferous Weed Isolates of Xanthomonas campestris Yield Insight into Pathovar Genomic Relationships and Genetic Determinants of Host and Tissue Specificity[2]Authors: Zoë E. Dubrow, Sara C. D. Carpenter, Morgan E. Carter, Ayress Grinage, Carine Gris, Emmanuelle Lauber, Jules Butchachas, Jonathan M. Jacobs, Christine D. Smart, Matthew A. Tancos, Laurent D. Noël, and Adam J. Bogdanove Publication: MPMI Vol. 35, No. 9, 2022, pp. 791–802 File: mpmi-01-22-0024-r.pdfDownload mpmi-01-22-0024-r.pdf This source is a journal article pertaining to primary research that is more so focused on the genetic relationships of the different pathovars isolates of this species. They tend to cause different diseases in brassicaceous hosts, while having specific determinants of host range and tissue specificity. This is an area of research that hasn't been well understood before, so it would be valuable to include in the page, especially considering there is already a section related to pathovars. That said, I plan to incorporate information from this specific source to provide distinction between the different pathovars, building off of discussion of the plant-bacterium interactions, as the current page really only lists some pathovars. Therefore, I will primarily be adding information to an existing section (along with a citation), but in a way that it makes that existing section more of an actual section with information as opposed to simply being a list.
Title:A multilocus sequence analysis of Xanthomonas campestris reveals a complex structure within crucifer-attacking pathovars of this species[3]Authors: E. Fargier, M. Fischer-Le Saux, C. Manceau Publication: Systematic and Applied Microbiology 34 (2011) 156–165 File: 1-s2.0-S0723202010001232-main.pdfDownload 1-s2.0-S0723202010001232-main.pdf This specific source is a journal article that focuses on primary research pertaining to the genetic relatedness of strains assigned to six different pathovars when in comes to black rot, leaf spot, and bacterial blight. Multilocus sequence analysis was used to study this along with the clonal evolution that has been found to be driven by the differential adaptation to the different cruciferous hosts. This information can be particularly important when considering the development of molecular techniques to identify these pathogens and improve the detections methods for plant and seed health. That said, I plan to use this information to in combination with the previous two sources mentioned. At this moment, I don't think that I will necessarily make a new section with this information. Instead, I think a lot of the information in this source could complement the new section I would like to create to discuss the plant-bacterium interactions and the information I add to the pathovars section that already exists. Therefore, I would be adding new citations to those sections again.
