“…Aubergine (eggplant; Solanum melongena ) is the third most economically important crop belonging to the Solanum genus after potato and tomato (Rotino et al ., ). It is cultivated worldwide with a total production of over 49 million tonnes reported in 2013, mainly in Asia (93% of both world production and harvested area), particularly China, India, Indonesia and Iran, followed by Africa and the subtropical areas, including the Mediterranean regions (predominantly Egypt, Turkey, Spain and Italy) (http://faostat3.fao.org/browse/Q/QC/).…”

“…Indeed, the two fungal wilts caused by Vd (Fradin & Thomma, ) and Fom (Cappelli et al ., ) are among the most serious diseases of aubergine. 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 ., ). Moreover, molecular and phenotypic characterizations of Fusarium oxysporum showed different levels of virulence in the different isolates collected (Altinok et al ., ) that were not always correlated by the resistances identified in the aubergine gene pool.…”

“…Furthermore, S. melongena progenitors, allied and wild relatives are an important reserve of potential genetic variability for the traits underlying many agronomic and qualitative features of the plant and fruit, as well as a source of valuable resistance to diseases and pests. For this reason, many allied and wild relatives have been employed to introgress traits of interest into the gene pool of cultivated aubergine (Rotino et al ., ).…”

“…S. sodomaeum ) into the S. melongena gene pool through a sexual cross between these two species, followed by several cycles of backcrosses with recurrent aubergine lines (Liu et al ., ). Conversely, full Fom resistance was introgressed from the allied species S. aethiopicum through somatic hybridization followed by anther culture of the tetraploid somatic hybrid to obtain dihaploid plants that were backcrossed with different typologies of recurrent aubergines (Rotino et al ., ). Advanced introgression lines (ILs) were obtained through six to eight cycles of backcross and selection, followed by selfing and/or anther culture to obtain pure lines.…”

Phenotype and gene expression analyses of the Rfo‐sa1 resistant aubergine interaction with Fusarium oxysporum f. sp. melongenae and Verticillium dahliae

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.

“…Unfortunately the latter remain largely unexploited and a limited number of reports on the use of the variation available in the wild species has been reported [17,20,28] while, to our knowledge, no modern commercial varieties of eggplants carry introgression from wild species.…”

Coding SNPs analysis highlights genetic relationships and evolution pattern in eggplant complexes

Brinjal (Solanum melongena), scarlet (S. aethiopicum) and gboma (S. macrocarpon) eggplants are three Old World domesticates. The genomic DNA of a collection of accessions belonging to the three cultivated species, along with a representation of various wild relatives, was characterized for the presence of single nucleotide polymorphisms (SNPs) using a genotype-by-sequencing approach. A total of 210 million useful reads were produced and were successfully aligned to the reference eggplant genome sequence. Out of the 75,399 polymorphic sites identified among the 76 entries in study, 12,859 were associated with coding sequence. A genetic relationships analysis, supported by the output of the FastSTRUCTURE software, identified four major sub-groups as present in the germplasm panel. The first of these clustered S. aethiopicum with its wild ancestor S. anguivi; the second, S. melongena, its wild progenitor S. insanum, and its relatives S. incanum, S. lichtensteinii and S. linneanum; the third, S. macrocarpon and its wild ancestor S. dasyphyllum; and the fourth, the New World species S. sisymbriifolium, S. torvum and S. elaeagnifolium. By applying a hierarchical FastSTRUCTURE analysis on partitioned data, it was also possible to resolve the ambiguous membership of the accessions of S. campylacanthum, S. violaceum, S. lidii, S. vespertilio and S. tomentsum, as well as to genetically differentiate the three species of New World Origin. A principal coordinates analysis performed both on the entire germplasm panel and also separately on the entries belonging to sub-groups revealed a clear separation among species, although not between each of the domesticates and their respective wild ancestors. There was no clear differentiation between either distinct cultivar groups or different geographical provenance. Adopting various approaches to analyze SNP variation provided support for interpretation of results. The genotyping-by-sequencing approach showed to be highly efficient for both quantifying genetic diversity and establishing genetic relationships among and within cultivated eggplants and their wild relatives. The relevance of these results to the evolution of eggplants, as well as to their genetic improvement, is discussed.

Crop wild relatives (CWRs) have barely been used in eggplant (Solanum melongena) breeding. However, introgression breeding may help in coping with the challenges posed by climate change. During the rainy and dry seasons, we evaluated nine accessions of eggplant, nine accessions of seven related species (of which six are CWRs and one is a cultivated relative), and 12 interspecific hybrids. Drought tolerance scores, calculated as ratios of growing rates and ratios of mean values during the rainy and dry seasons, were obtained for vegetative growth and yield‐related traits. Considering the vegetative growth and yield‐related traits evaluated, the F1 hybrid progenies of eggplant with S. insanum MEL1 × INS2 and MEL4 × INS3, S. anguivi MEL6 × ANG1, and S. dasyphyllum MEL6 × DAS1, plus the S. sysimbriifolium accession SIS1, displayed drought tolerance. Small to large gaps were observed between phenotypic and genotypic CVs of drought tolerance scores, reflecting variable influence of environmental factors on drought tolerance of the traits evaluated. In addition, the narrow‐sense heritability was generally moderate, indicating that genes with dominance and/or epistasis effects may be involved in the expression of drought tolerance. High genotypic correlations for drought tolerance scores between pairs of traits such as branching index and leaf length, leaf petiole diameter and plant height, number of stamens per flower, and fruit pedicel length suggest that drought tolerance of these traits is controlled by genes that are in linkage disequilibrium and/or have pleiotropic effects. The results are relevant for the development of drought‐tolerant cultivars of eggplant.
