    Determination of Resistance Levels To Clavibacter Michiganensis Subsp. Michiganensis in Some Solanum Species
    (Ege Tarımsal Araştırma Enstitüsü, 2022) Frary, Anne; Şanver, Utku; Akköse Baytar, Asena; Özaktan, Hatice; Doğanlar, Sami
    Clavibacter michiganensis subsp. michiganensis (Cmm), is a devastating bacterial disease agent causing bacterial wilt and canker in tomatoes. There is no definitive solution to prevent yield losses by Cmm in tomatoes. Moreover, there is currently no commercially successful Cmm resistant tomato cultivar on the market. Therefore, we aimed to determine the tolerance level of some tomato accessions to Cmm in the present study. For this purpose, we screened seven tomato accessions representing four species (Solanum arcanum, S. habrochaites, S. pennellii, and S. peruvianum) from Peru, Ecuador, and Mexico against the highly virulent isolates Cmm-244 and Cmm-9. A root immersion method was used to identify new sources of resistance to this important disease. Two accessions, S. habrochaites LA1777, and S. arcanum LA2157 were found to be moderate and highly tolerant, respectively, and could serve as tolerance resources for tomato breeding in Türkiye. These materials can also be investigated more extensively to determine their intrinsic Cmm tolerance mechanism.

    Plum is an important fruit worldwide and has high nutritional value. Prunus cerasifera Ehrh., a type of European plum species, is very popular in Turkey and is usually eaten at the green, unripe stage. In this work for the first time, the genetic diversity and population structure of the 66 accessions housed in the Turkish National P. cerasifera collection were investigated using molecular markers. A total of 47 Sequence-Related Amplified Polymorphism (SRAP) primer pairs were used and found to be highly polymorphic with 98% of the 495 amplified alleles providing polymorphism. Average diversity of the accessions was 0.39 as determined using the dice coefficient and was similar to P. cerasifera germplasm from France, Iran and Belarus but higher than that from China. This difference was expected as Turkey, Iran and Belarus are within the geographical origin of this species which was distributed to Europe during ancient times. The genetic relationships among accessions of the germplasm collection were assessed using unweighted neighbor joining dendrogram and population structure analyses. The dendrogram and population structure results were strongly correlated as both methods clustered the material into two main groups with a much smaller third admixed group. The analysis also indicated that Can and Papaz types, despite their morphological differences are not genetically distinct and provides information about genetic relationships that can be used in future plum breeding.
