“…Another major challenge for the global production of Musaceae species is the development of cultivars resistant to biotic stressors, represented by their primary pests, the banana root borer (Cosmopolites sordidus) and the nematodes Meloidogyne spp., Pratylenchus coffeae, and Radopholus similis [13][14][15][16][17][18][19], and disease-causing pathogens, including banana bunchy top virus (BBTV) [20,21], Xanthomonas vasicola pv. musacearum causing bacterial wilt [22][23][24][25], Pseudocercospora fijiensis causing black Sigatoka [26][27][28][29], and Fusarium oxysporum f. sp. cubense (FOC) causing Fusarium wilt [30][31][32][33].…”

The fungus Fusarium oxysporum f. sp. cubense (FOC), tropical race 4 (TR4), causes Fusarium wilt of banana, a pandemic that has threatened the cultivation and export trade of this fruit. This article presents the first systematic review of studies conducted in the last 10 years on the resistance of Musa spp. to Fusarium wilt. We evaluated articles deposited in different academic databases, using a standardized search string and predefined inclusion and exclusion criteria. We note that the information on the sequencing of the Musa sp. genome is certainly a source for obtaining resistant cultivars, mainly by evaluating the banana transcriptome data after infection with FOC. We also showed that there are sources of resistance to FOC race 1 (R1) and FOC TR4 in banana germplasms and that these data are the basis for obtaining resistant cultivars, although the published data are still scarce. In contrast, the transgenics approach has been adopted frequently. We propose harmonizing methods and protocols to facilitate the comparison of information obtained in different research centers and efforts based on global cooperation to cope with the disease. Thus, we offer here a contribution that may facilitate and direct research towards the production of banana resistant to FOC.

“…Most of the species are of phytosanitary concern since they are causal agents of diseases with a global impact on seed, plant and food trade, being responsible for important economic and environmental losses [6,7]. The contours of this genus have tremendously evolved with the transfer of species into related genera (e.g., [8,9]), the description of novel species [10,11] and taxonomic rearrangements leading to synonymy of taxa [12][13][14][15].…”

Trends in Molecular Diagnosis and Diversity Studies for Phytosanitary Regulated Xanthomonas

Bacteria in the genus Xanthomonas infect a wide range of crops and wild plants, with most species responsible for plant diseases that have a global economic and environmental impact on the seed, plant, and food trade. Infections by Xanthomonas spp. cause a wide variety of non-specific symptoms, making their identification difficult. The coexistence of phylogenetically close strains, but drastically different in their phenotype, poses an added challenge to diagnosis. Data on future climate change scenarios predict an increase in the severity of epidemics and a geographical expansion of pathogens, increasing pressure on plant health services. In this context, the effectiveness of integrated disease management strategies strongly depends on the availability of rapid, sensitive, and specific diagnostic methods. The accumulation of genomic information in recent years has facilitated the identification of new DNA markers, a cornerstone for the development of more sensitive and specific methods. Nevertheless, the challenges that the taxonomic complexity of this genus represents in terms of diagnosis together with the fact that within the same bacterial species, groups of strains may interact with distinct host species demonstrate that there is still a long way to go. In this review, we describe and discuss the current molecular-based methods for the diagnosis and detection of regulated Xanthomonas, taxonomic and diversity studies in Xanthomonas and genomic approaches for molecular diagnosis.

“…Recent work based primarily on DNA sequence and fatty acid data has shown that strains of Xcm have very close homology to strains of Xanthomonas vasicola and most likely belong to this species. Accordingly, the name X. vasicola has been proposed for Xcm (Aritua et al, 2008;Studholme et al, 2020), though this has not been formally approved as a new combination of names by the International Committee on Systematic Bacteriology. Therefore, the previous name Xcm is still the current official name.…”

Enset (Ensete ventricosum) bacterial wilt (EBW) incited by Xanthomonas campestris pv. musacearum (Xcm) is threatening enset production in southwestern Ethiopia. The objectives of this study were to determine the pathogenicity of Xcm isolates and select enset clones resistant to pathogenic Xcm isolates in the study areas. A total of 30 Xcm isolates were subjected to pathogenicity tests on a susceptible enset clone Yeko and all were found pathogenic. Out of 30 pathogenic isolates, three isolates representing three altitude groups [lowland (1470 m.a.s.l), midland (1938 m.a.s.l) and highland (2360 m.a.s.l)] were used for enset clonal evaluation trials. In the clone evaluation trial, 15 enset clones (13 local and a tolerant and susceptible check) were evaluated for 2 years (2017 and 2018) under screen house conditions at Tepi National Spice Research Center, southwestern Ethiopia. The experiments were factorially arranged in a completely randomized design with three replications. An aliquot of 10 ml of the bacterial cell suspension with a concentration of 1 × 10 8 cfu/ml was inoculated into the second innermost leaf petiole of enset using a sterile hypodermic syringe. Starting from 15 days after inoculation (DAI), data were collected on
