“…This could also be the case for the isolates Ara1 and Ara2. The interplay of the exchanged pathogenicity genes with a different core genome, which is adapted to local conditions, could explain the higher virulence of isolate FoxPDa3 compared to the other Foc isolates of group St9/StQ, as observed in the greenhouse assay (Deltour et al ., ).…”

“…On the farm, banana cv. Maçã (subgroup: Silk) was affected by fusarium wilt, but disease was variable and variation could be attributed to differences in disease suppressiveness of the soil (Deltour et al ., ). Soil samples, different graminoids, pseudostem and roots of banana cultivars Ouro (AA, Sucrier subgroup, resistant to Foc race 1) and Prata (AAB, Pome subgroup, moderately susceptible to Foc race 1) and pseudostem of cv.…”

Comparative analysis of pathogenic and nonpathogenic Fusarium oxysporum populations associated with banana on a farm in Minas Gerais, Brazil

Fusarium wilt is one of the most devastating diseases on banana. The causal agent, Fusarium oxysporum f. sp. cubense (Foc) is genetically diverse and its origin and virulence are poorly understood. In this study, pathogenic Foc isolates and nonpathogenic F. oxysporum isolates from Minas Gerais in Brazil were compared using EF-1a and IGS sequences. This allowed the examination of the origin and evolutionary potential of Foc in a country outside the region of origin of the banana plant. Two different sequence types were found among Foc isolates. One appeared to be of local origin because it was identical to the sequence type of the largest group of nonpathogenic isolates. To explore if the 'local' Foc isolates had acquired pathogenicity either independently through coevolution with the host, or through horizontal gene transfer (HGT) of pathogenicity genes from other, probably introduced, Foc isolates, the presence and sequence of putative SIX effector genes were analysed. Homologues of SIX1, SIX3 and SIX8 were found. SIX1 sequences were identical and exclusively found in all pathogenic isolates, while variable ratios of sequences of multicopy gene SIX8 were found among nonpathogenic and different pathogenic isolates. This observation supports the HGT hypothesis. Horizontal transfer of genes between isolates of F. oxysporum has important implications for the development of reliable diagnostic tools and effective control measures. Full genome sequencing is required to confirm HGT and to further unravel the virulence mechanisms of forma specialis cubense.

“…Panama disease of banana is difficult to control due to the survival of Foc4 as chlamydospores in soil or as a saprophyte of non-host plants (Deltour et al, 2017). In our previous study, application of a biofertilizer produced by fermentation of compost and amino acids inoculated with a Bacillus sp.…”

Summary Microbiome plays a key role in determining soil suppressiveness against invading pathogens. Our previous study revealed that microbial community of bulk soil could be manipulated by lime and ammonium bicarbonate fumigation followed by biofertilizer application. However, the assembly of microbial community suppressive to banana Panama disease in the rhizosphere is still unclear. In this study, we used high‐throughput sequencing and quantitative PCR to explore the assembly of rhizosphere microbiome associated with banana Panama disease suppression in a two‐seasonal pot experiment. We found biofertilizer applied to lime and ammonium bicarbonate fumigated soil significantly ( P < 0.05) reduced the abundance of rhizosphere Fusarium oxysporum compared to biofertilizer applied to non‐fumigated soil. Principal coordinate analysis revealed that biofertilizer applied to lime and ammonium bicarbonate fumigated soil re‐shaped the rhizosphere bacterial community composition by increasing the phylogenetic relatedness, and stimulating indigenous microbes, for example , Gemmatimonas , Sphingomonas , Pseudomonas , Lysobacter and Bacillus . Co‐occurrence analysis revealed that potential species involved in disease suppression were more interrelated in disease‐suppressive soils. Taken together, lime and ammonium bicarbonate fumigation followed by biofertilizer application could induce banana rhizosphere to assemble beneficial microbes dominated consortia to suppress banana Panama disease.

“…For example, Pattison et al (2014) found that Fusarium wilt expression is a function of water stress (defi cit and excess) and heat unit requirement of banana. Deltour et al (2017) showed that the higher the clay content, pH, and electric conductivity in soil, the lesser severity of Fusarium wilt. Meanwhile, according to Perez-Vicente et al (2014), severe infection is observed during the warmer and wet months of the year.…”

Summary This study used Maximum Entropy (MaxEnt) to explore potential environmental determinants of Fusarium wilt occurrence on banana in south-central part of the Philippines. Different variables representing topographic, bioclimatic, and edaphic features of an area were tested against data of Fusarium wilt occurrence. Based on the results, precipitation during the driest month, precipitation during the wettest month, precipitation of the warmest quarter, slope, and elevation were the most important variables for predicting the probability of Fusarium wilt occurrence on banana. Results also suggest that among the variables tested, precipitation had the major contribution to the occurrence of Fusarium wilt.
