Cucumber (Cucumis sativus L.) damping-off disease caused by Phytophthora melonis is a limiting factor affecting cucurbit production. This study assessed a collection of 38 domestic and exotic commercial cucumber genotypes for damping-off resistance at transplanting and 50% flowering. Plants were classified using a four-score scale, the average damping-off percentage ranging from 7.92% (resistant) to 88.01% [highly susceptible (HS)]. Most of the genotypes were susceptible and HS to P. melonis. These genotypes were analyzed with 15 inter-simple sequence repeat (ISSR) markers. A total of 317 bands were produced, of which 297 bands (93.69%) were polymorphic. The primer ISSR29 possessed the highest resolving power, polymorphic information content and marker index value, which could be the most informative primer for distinguishing cucumber genotypes. Cluster analysis and principal component analysis were carried out and there was a probable connection between cucumber genotypes and resistance level against P. melonis, indicating possible application for ISSR in studying disease resistance of cucumber and producing cultivars that resist damping-off. The expression of three candidate genes probably involved in the defence against P. melonis was quantified by quantitative real-time polymerase chain reaction in five cucumber genotypes showing different susceptibility to the pathogen. CsWRKY20, CsLecRK6.1 and LOX1 genes were differentially expressed depending on genotype in early stages of infection. LOX1 was the most expressed gene across experiments and the one that best discriminated between susceptible and resistant genotypes. These results are a valuable resource for future functional genomics studies to unravel the molecular mechanisms of C. sativus/P. melonis interaction.

Seven varieties of Chinese dwarf cherries were evaluated and compared with respect to their weight, diameter, titratable acidity, total soluble solids, color, polyphenol contents, ascorbic acid levels, anthocyanin profiles, enzymatic activity, and antioxidant capacity. The fruits are rich in phenolic content (339.07–770.30 mg/100 g fresh weight). Nine anthocyanins were obtained from fruits after chromatographic separation and their structures analyzed using HPLC-ESI-MS/MS. Cyanidin-3-glucoside was the major anthocyanin with 50.36–78.39% concentration. Three anthocyanins were reported for the first time in these cherries. They exhibit low polyphenol oxidase and peroxidase activities, but their superoxide dismutase activity is high (572.75–800.17 U/g FW). The highest amounts of soluble solid content (15.67 Brix %), total titratable acid (1.90%), ascorbic acid (18.47 mg/100 g FW), and total anthocyanin (152.66 mg/100 g FW) were observed. Three methods (DPPH-scavenging ability, oxygen radical absorbance capacity assay, and cellular antioxidant activity assay) were employed to evaluate the antioxidant capacity of the phenolic extracts of these cherries. Number 5 has the highest values of ORAC and CAA of 205.68 μmol TE/g DM and 99.67 μmol QE/100 g FW, respectively.

“…This difference could be explained by the fact that the samples were collected from individual trees dispersed in distant areas from Latakia. The high level of genetic similarity between M. nigra genotypes was also observed in the study of Wang et al (2017), where low diversity among 42 mulberry genotypes was revealed using 17 ISSR primers (average of Nei's and Shannon's information index 0.116 and 0.174, respectively).…”

In Syria, there are ancient wild, and cultivated mulberry trees, traditionally used to feed the silkworm Bombyx mori L., and cultivated for their edible fruits. Evaluating genetic relationships is imperative for the identification, conservation, and improvement of mulberry germplasm. The present study addresses the use of inter simple sequence repeat (ISSR) and simple sequence repeat (SSR) markers to estimate genetic diversity within and between two different mulberry species (49 genotypes of Morus nigra cultivar. El-Shami) and (8 genotypes of Morus alba) from different regions of Syria (Al-Qunaitra, Tartus and Latakia). Fifteen ISSR primers and six SSR primer pairs were used in the analysis. Overall, genetic diversity within M. alba and M. nigra was low (0.22). The genetic distance between the two species (M. nigra and M. alba) was higher (0.72) than that within the species (0.3). A dendrogram based on SSR and ISSR results showed the clustering of samples according to the species and to their geographic collection sites. The level of polymorphism detected between samples using the ISSR marker (90.31%) was higher than that detected with SSR marker (68.05%).The genotypes collected from Al-Qunaitra were very similar as the coefficient of genetic distance -CGD-was less than 0.1, while genotypes from Latakia were more distant (CGD is 0.33). In general, the level of genetic diversity between the analyzed genotypes of M. nigra cv. El-Shami was lower than between the samples of M. alba.
