This review was to review with an objective of reviewing the biology, economic importance of CBB of common bean crop disease and its management options, with an emphasis on the future research direction and priorities. CBB disease, caused by the gram-negative bacterial pathogen Xanthomonas axonopodis pv. phaseoli (Xap) and its fuscans variant Xanthomonas fuscans subsp. fuscans (Xff) is the major bottleneck in bean production in the world as well as in Ethiopia. It is a serious bacterial disease of common bean which causes lesions on the leaves, stems, pods and seeds of the plant. The disease affects seed quality and can reduce yield by up to 45%, may be more in susceptible cultivars. CBB is very difficult to control due to seed-borne nature of the bacteria and its capacity to produce huge amounts of secondary inoculum. -
Horizontal Gene Transfer Plays a Major Role in the Pathological Convergence of Xanthomonas Lineages on Common Bean Nicolas W
Chen et al. BMC Genomics (2018) 19:606 https://doi.org/10.1186/s12864-018-4975-4 RESEARCHARTICLE Open Access Horizontal gene transfer plays a major role in the pathological convergence of Xanthomonas lineages on common bean Nicolas W. G. Chen1†, Laurana Serres-Giardi1†, Mylène Ruh1, Martial Briand1, Sophie Bonneau1, Armelle Darrasse1, Valérie Barbe2, Lionel Gagnevin3,4, Ralf Koebnik4 and Marie-Agnès Jacques1* Abstract Background: Host specialization is a hallmark of numerous plant pathogens including bacteria, fungi, oomycetes and viruses. Yet, the molecular and evolutionary bases of host specificity are poorly understood. In some cases, pathological convergence is observed for individuals belonging to distant phylogenetic clades. This is the case for Xanthomonas strains responsible for common bacterial blight of bean, spread across four genetic lineages. All the strains from these four lineages converged for pathogenicity on common bean, implying possible gene convergences and/or sharing of a common arsenal of genes conferring the ability to infect common bean. Results: To search for genes involved in common bean specificity, we used a combination of whole-genome analyses without a priori, including a genome scan based on k-mer search. Analysis of 72 genomes from a collection of Xanthomonas pathovars unveiled 115 genes bearing DNA sequences specific to strains responsible for common bacterial blight, including 20 genes located on a plasmid. Of these 115 genes, 88 were involved in successive events of horizontal gene transfers among the four genetic lineages, and 44 contained nonsynonymous polymorphisms unique to the causal agents of common bacterial blight. Conclusions: Our study revealed that host specificity of common bacterial blight agents is associated with a combination of horizontal transfers of genes, and highlights the role of plasmids in these horizontal transfers. -

Express-PRA for Xanthomonas albilineans – Research and Breeding – Prepared by: Julius Kühn-Institute, Institute for national and international Plant Health; by: Dr. René Glenz, Dr. Anne Wilstermann; on: 19-10-2020 (Translation by Elke Vogt-Arndt) Initiation: Application for an Express-PRA by the Federal State Bavaria resulting from a request for a special authorisation for the movement and use of the organism for research and breeding purposes. Express-PRA Xanthomonas albilineans (Ashby 1929) Dowson 1943 Phytosanitary risk for Germany high medium low Phytosanitary risk for EU high medium low Member States Certainty of the assessment high medium low Conclusion The bacterium Xanthomonas albilineans is endemic to the tropics and subtropics. It causes leaf scald to sugarcane and so far, it is not present in Germany and the EU. So far, the bacterium is not listed, neither in the Annexes of Regulation (EU) 2019/2072 nor by EPPO. Xanthomonas albilineans infects plants of the grass family and is a significant pest on sugarcane. Under certain conditions, relevant damage occurred sporadically on maize, too. Due to inappropriate climatic conditions, it is assumed that X. albilineans cannot establish in the open field in Germany. The establishment in southern European EU Member States is not expected. However, there is a lack of sufficient data to completely rule out the possibility of the establishment of the bacterium. Due to its presumably low damage potential to maize, X. albilineans poses a low phytosanitary risk for Germany and other EU-Member States. Thus, Xanthomonas albilineans is not classified as a quarantine pest and Article 29 of Regulation (EU) 2016/2031 does not apply. -

Specific approval and amendment First approved in 2004-09. Revised in 2016-09 and 2018-XX.2 1 Introduction Xylella fastidiosa causes many important plant diseases such as Pierce's disease of grapevine, phony peach disease, plum leaf scald and citrus variegated chlorosis disease, olive scorch disease, as well as leaf scorch on almond and on shade trees in urban landscapes, e.g. Ulmus sp. (elm), Quercus sp. (oak), Platanus sycamore (American sycamore), Morus sp. (mulberry) and Acer sp. (maple). Based on current knowledge, X. fastidiosa occurs primarily on the American continent (Almeida & Nunney, 2015). A distant relative found in Taiwan on Nashi pears (Leu & Su, 1993) is another species named X. taiwanensis (Su et al., 2016). However, X. fastidiosa was also confirmed on grapevine in Taiwan (Su et al., 2014). The presence of X. fastidiosa on almond and grapevine in Iran (Amanifar et al., 2014) was reported (based on isolation and pathogenicity tests, but so far strain(s) are not available). The reports from Turkey (Guldur et al., 2005; EPPO, 2014), Lebanon (Temsah et al., 2015; Habib et al., 2016) and Kosovo (Berisha et al., 1998; EPPO, 1998) are unconfirmed and are considered invalid. Since 2012, different European countries have reported interception of infected coffee plants from Latin America (Mexico, Ecuador, Costa Rica and Honduras) (Legendre et al., 2014; Bergsma-Vlami et al., 2015; Jacques et al., 2016). -

Almeida 6, Rafael Nascimento2, Abhaya M. Dandekar7, Paulo A. Zaini2,7, João C. Setubal3, David S. Guttman 4,8 & Leandro Marcio Moreira1,9 The Xanthomonadaceae family consists of species of non-pathogenic and pathogenic γ-proteobacteria that infect diferent hosts, including humans and plants. In this study, we performed a comparative analysis using 69 fully sequenced genomes belonging to this family, with a focus on identifying proteins enriched in phytopathogens that could explain the lifestyle and the ability to infect plants. Using a computational approach, we identifed seven phytopathogen-enriched protein families putatively secreted by type II secretory system: PheA (CM-sec), LipA/LesA, VirK, and four families involved in N-glycan degradation, NixE, NixF, NixL, and FucA1. -

Originating from America, this bacterium caused recent epidemics in southern Europe and is thus considered an emerging pathogen. As the European regulations do not authorize antibiotic treatment in plants, alternative treatments are urgently needed to control the spread of the pathogen and eventually to cure infected crops. One such alternative is the use of phage therapy, developed more than 100 years ago to cure human dysentery and nowadays adapted to agriculture. The first step towards phage therapy is the isolation of the appropriate bacteriophages. With this goal, we searched Citation: Clavijo-Coppens, F.; Ginet, for phages able to infect Xf strains that are endemic in the Mediterranean area. However, as Xf N.; Cesbron, S.; Briand, M.; Jacques, is truly a fastidious organism, we chose the phylogenetically closest and relatively fast-growing M.-A.; Ansaldi, M. -
