During antagonistic coevolution between viruses and their hosts, viruses have a major advantage by evolving more rapidly. Nevertheless, viruses and their hosts coexist and have coevolved, although the processes remain largely unknown. We previously identified Tm-1 that confers resistance to Tomato mosaic virus (ToMV), and revealed that it encodes a protein that binds ToMV replication proteins a...

Cultivated tomato (Solanum lycopersicum L.) is susceptible to abiotic stresses, including drought and chilling stress, while its wild relative (Solanum habrochaites) exhibits tolerance to many abiotic stresses. Chilling roots to 6°C induces rapid-onset water stress by impeding water movement from roots to shoots. Wild S. habrochaites responds to root chilling by closing stomata and maintaining ...

A systematic screen of volatile terpene production in the glandular trichomes of 79 accessions of Solanum habrochaites was conducted and revealed the presence of 21 mono- and sesquiterpenes that exhibit a range of qualitative and quantitative variation. Hierarchical clustering identified distinct terpene phenotypic modules with shared patterns of terpene accumulation across accessions. Several ...

Eggplant (Solanum melongena) is amenable to grafting and this technique can be exploited to improve production of this vegetable crop. Here, we study the performance of the ‘Cristal F1’ eggplant cultivar grafted onto a total of 17 rootstocks, including five families, each of which is made by two parents and their hybrid, as well a commercial eggplant rootstock and a self-grafted control. Three ...

Bu çalışmada beş farklı yabani domates türüne, Tuta absoluta (Meyrick)’nın yumurta koyma tercihleri incelenmiştir. amaçla türleri olan Solanum arcanum (LA2152), habrochaites (LA0094), lycopersicum (LA0292), pimpinellifolium (LA0100) ve pennellii (LA0716) kontrol olarak seçilen hassas tür (S. cv Depar) ile birlikte denemeye alınmıştır. Çalışmadan elde edilen sonuçlara göre, içerisinde T. absolut...

Acylsugars are polyesters of short- to medium-length acyl chains on sucrose or glucose backbones that are produced in secretory glandular trichomes of many solanaceous plants, including cultivated tomato (Solanum lycopersicum). Despite their roles in biotic stress adaptation and their wide taxonomic distribution, there is relatively little information about the diversity of these compounds and ...

The wild species Solanum habrochaites is more cold tolerant than the cultivated tomato (S. lycopersicum). To explore the mechanisms underlying cold tolerance of S. habrochaites, seedlings of S. habrochaites LA1777 introgression lines (ILs), as well as the two parents, were evaluated under low temperature (4°C). The IL LA3969 and its donor parent LA1777 were found to be more cold tolerant than t...

Clavibacter michiganensis subsp. (Cmm), is a devastating bacterial disease agent causing wilt and canker in tomatoes. There no definitive solution to prevent yield losses by Cmm Moreover, there currently commercially successful resistant tomato cultivar on the market. Therefore, we aimed determine tolerance level of some accessions present study. For this purpose, screened seven representing fo...

The greenhouse whitefly, Trialeurodes vaporariorum Westwood, is the most common and abundant whitefly in Argentine horticultural greenhouse crops, especially in tomato (Solanum lycopersicum). Resistance in some wild tomato relatives, such as S. peruvianum, S. habrochaites and S. pennellii to the greenhouse whitefly has been described. The Mi gene confers effective resistance against several spe...
