“…Partial resistance/tolerance to most pathogens was found within the aubergine gene pool, but the resistance levels are often insufficient for effective use in breeding programmes (Rotino et al, 2014). Moreover, molecular and phenotypic characterizations of Fusarium oxysporum showed different levels of virulence in the different isolates collected (Altinok et al, 2014) that were not always correlated by the resistances identified in the aubergine gene pool.…”

Aubergine (eggplant) is susceptible to fungal wilts caused by Fusarium oxysporum f. sp. melongenae (Fom) and Verticillium dahliae (Vd). Wild and allied relatives represent a good source of resistance, and introgression lines (ILs) have been obtained through introgression of the Rfo‐sa1 locus conferring resistance to Fusarium oxysporum from Solanum aethiopicum into cultivated aubergine. In this work, a deep phenotype characterization was performed according to two parameters: progression of symptoms along the stem and disease severity in leaves. This analysis showed that the Fom‐resistant ILs carrying introgression of the Rfo‐sa1 locus displayed significantly improved tolerance to Verticillium attack after a preliminary inoculation with F. oxysporum. This positive effect was particularly evident when Verticillium inoculation was performed simultaneously or after Fusarium inoculation. Transcript profiling carried out using a combination of suppression subtractive hybridization (SSH), microarray and qRT‐PCR analyses of roots inoculated with selected combinations of fungal pathogens enabled the identification of 164 differentially expressed genes between inoculated and uninoculated plants or between different stages after pathogen infection. Overall, the results highlighted a number of candidate genes putatively involved in early defence responses or signalling pathways activated upon infection of aubergine with either Fom and/or Vd, and thus leading to a broad Rfo‐sa1‐mediated tolerance against both these wilt pathogens.

“…Despite sterilization of soil using chemicals or hot water, these diseases remain a considerable issue in the production of tomato, eggplant and pepper (Postic et al, ). The safest way of preventing these diseases may be the use of resistant rootstocks or cultivars (Altinok, Can, Boyaci, & Topcu, ). Molecular and genetic characterization of the Fusarium pathogen that is indigenous in a region or country is a critical step in developing resistant cultivars (Altinok & Can, ).…”

In the current study, 160 pathogenic strains of Fusarium oxysporum collected from tomato, eggplant and pepper were studied. Eighteen inter‐primer binding site (iPBS)‐retrotransposon primers were used, and these primers generated 205 scorable polymorphic bands. The number of polymorphic bands per primer varied between 9 and 19, with a mean of 11 bands per primer. The highest polymorphism information content (PIC) value was determined as 0.27, and the lowest was 0.05. The unweighted pair‐group method with arithmetic averages (UPGMA) dendrogram including a heat map revealed that the 160 pathogenic strains of F. oxysporum were divided into two main clusters. The first cluster mainly included F. oxysporum f. sp. capsici (FOC) and F. oxysporum f. sp. melongenae (FOMG) isolates. The second cluster mainly comprised F. oxysporum f. sp. lycopersici (FOL) and F. oxysporum f. sp. radicis lycopersici (FORL) isolates. The highest percentage of loci in significant linkage disequilibrium (LD) was detected for FOL, whereas the lowest level of LD was found for FOC, and 95.2%, 99.4%, 99.1% and 97.4% of the relative kinship estimates were less than 0.4 for FOL, FOMG, FORL and FOC, respectively. LD differences were detected among formae speciales, and LD was higher in FOL as compare to FOC species. The findings of this study confirm that iPBS‐retrotransposon markers are highly polymorphic at the intraspecific level in Fusarium spp.

“…This disease is affects eggplant cultivations in both greenhouses and open field cultivations (Mutlu et al, 2008). Most of the important varieties including hybrids are susceptible to Fusaium wilt Altinok et al, 2014). The most effective way to control the disease is to use resistant varieties.…”
