“…Based on the data obtained, it is concluded that the resistance of rootstocks to bacterial wilt varied according to the strains and the experimental conditions performed, as already described in other studies (Ahmed et al, 2013;Albuquerque, et al, 2021;Santiago et al, 2017). In addition, these results reinforce the importance to evaluate combinations of rootstock and grafting according to the climatic conditions and isolate from each region.…”

“…The level of resistance of tomato rootstocks to bacterial wilt is highly related to environmental factors and the high genetic variability of Ralstonia species (Rivard et al, 2012;Santiago et al, 2017), especially in Brazil, which is considered an important center of genetic variability for those bacteria (Santiago et al, 2017). The combinations of rootstock and graft must be tested according to the climatic conditions and isolated from each region, but the high genetic variability found in populations of the pathogen has hampered the use of resistance sources, since the stability of resistance to bacterial wilt in Solanaceae is highly affected by the variability of the pathogen and by factors linked to the environment (Rivard et al, 2012;Ahmed et al, 2013;Albuquerque et al, 2021;Santiago et al, 2017).…”

Bacterial wilt limits tomato production and resistant rootstocks could be important for the integrated management of the disease. Since there is an interaction between local bacterial strains and tomato genotype, this study aimed to evaluate 14 tomato rootstocks to bacterial wilt in the Mata mesoregion of Pernambuco state, Brazil. The rootstocks reaction to two sequevars of Ralstonia solanacearum and two of R. pseudosolanacearum was evaluated in four experiments carried out in the greenhouse using the completely randomized experimental design, with four replications composed of four plants each. Seven genotypes were selected to evaluate the reaction to bacterial wilt as rootstocks grafting in tomato plants ‘Tomini F1’ in a production area with disease history in the Chã Grande municipality, using randomized block design with four plants per treatment in each block. In the field experiment, disease symptoms were not observed in the grafted plants in ‘Guardião’, ‘Woodstock’, and ‘Yoshimatsu’. Regarding all experiments, ‘Guardião’ and ‘Muralha’ showed the best resistance levels and could be used in the integrated management of bacterial wilt and studied in plant breeding programs.

“…In spite of Moko ecotype identification (Albuquerque et al, 2014(Albuquerque et al, , 2021a and genomic characterization of representative strains by Silva et al (2020) and Pais et al (2021), no genomic studies have looked the different symptomatology caused by the R. solanacearum Moko ecotype. Therefore, the objective of this study was to investigate the representatives of the Moko ecotype that induce different symptoms in banana trees using comparative genomics and phylogenomic approaches.…”

Banana tree bacterial wilt is caused by the Ralstonia solanacearum Moko ecotype. These strains vary in their symptom progression in banana, and are classified as typical Moko variants (phylotype IIA and IIB strains from across Central and South America), Bugtok variant (Philippines), and Sergipe facies (the states of Sergipe and Alagoas, Brazil). This study used comparative genomic and phylogenomic approaches to identify a correlation between the symptom progression of the Moko ecotypes based on the analysis of 23 available genomes. Average nucleotide identity and in silico DNA-DNA hybridization revealed a high correlation (>96% and >78%, respectively) between the genomes of Moko variants. Pan-genome analysis identified 21.3% of inheritable regions between representatives of the typical Moko and Sergipe facies variants, which could be traced to an abundance of exclusive homolog clusters. Moko ecotype genomes shared 1,951 orthologous genes, but representatives with typical symptoms did not display unique orthologues. Moreover, Bugtok disease and Sergipe facies genomes did not share any unique genes, suggesting convergent evolution to a shared symptom progression. Overall, genomic and phylogenomic analyses were insufficient to differentiate the Moko variants based on symptom progression.
