“…They are genetically a very diverse group and play a major role in modern society and economy. Fruit and vegetables are an important component of traditional food but are also central to healthy diets of modern urban populations (Hricova et al, 2016;Sakar et al, 2016;Saridas et al, 2016;Solmaz et al, 2016). Sea buckthorn, a thorny deciduous shrub with a distinctive tolerance to drought, cold, and salinity, is naturally distributed over Asia and Europe (Jain et al, 2010).…”

Sea buckthorn (Hippophae rhamnoides) is an ecologically and economically valuable species that has been widely cultivated as a new berry crop rich in nutritional and medicinal compounds. RNA Sequencing (RNA-Seq) simple sequence repeat (SSR) markers were developed to evaluate the genetic relationships among 91 plants of 31 cultivars from two subspecies, mongolica and sinensis, as well as intraspecific hybrids between them. A total of 7540 RNA-Seq SSRs were identified as potential molecular markers, in which AG/CT (27.57%) was the most abundant unit type. AT/AT (9.93%), and AAG/CTT (11.95%) are the other main repeat motifs. A total of 110 primer pairs were randomly selected for validation of amplification. Seventeen SSR loci, located in genes encoding metabolic processes and cellulose synthases, were identified to be polymorphic among different sea buckthorn cultivars. These SSR loci generated 48 alleles, ranging from 2 to 5 per locus. Cluster analysis based on the proportion of shared alleles and unweighted pair group method with arithmetic average (UPGMA) algorithm divided all the genotypes into two main groups, with all of the ssp. sinensis cultivars (native to China) and hybrids in one group and ssp. mongolica cultivars (introduced from Russia) in the other group, which was in good agreement with their taxonomic classification. The RNA-Seq SSRs developed in this study have a potential use in the conservation of sea buckthorn germplasm and marker-assisted breeding (MAB).

associated with yield (number and size of inflorescences), chemical composition of inflorescences, growth characteristics, uniformity of flowering, and resistance to pests and diseases. Our studies indicate that interspecific hybridization efficiently increases the variation in the chemical composition of elderberry fruits (Mikulic-Petkovsek et al., 2014.Polyphenolic compounds are regarded as important chemical compounds due to their high antioxidant efficacy (Ozgen et al., 2010), which has a positive impact on people's health, and may impede the development of cancer and inhibit oxidative damage (Akbulut et al., 2009). Phenolic compounds possess various pharmacological effects: antiviral, antibacterial, antiinflammatory, and anticancer functions. Positive effects of flavonoids and phenolic acids have also been reported in connection with cardiovascular diseases (Olthof et al., 2001;Netzel et al., 2002;Murkovic et al., 2004). It has been reported that the concentration of phenolics is closely connected with the antioxidant activity of plant tissue and thus an assessment of the phenolic profile is important for the determination of antioxidant capacity (Choi and Kwak, 2014). The antioxidant activity of elderberry inflorescence extracts ranged from 44.8 to 118.2 mM TE/kg DW (Mikulic-Petkovsek et al., 2016).

“…The seeds of the Amaranthus cruentus L. Ficha were treated by the gamma dose of 175 Gy In FAO/IAEA Seibersdorf, Austria. The mutagenic effect that was genetically fixed in the following generations (M 1 –M 15 ) was connected to the decreased weight of thousand seeds (Hricová et al., ). Different molecular and DNA‐based marker method was used to characterize the control genotype Ficha and the Mx generations including the C82 line (now variety Pribina), and the difference of this line was confirmed in this studies at the molecular level (Hricová, Kečkešová, Gálová, Libiaková, & Gajdošová, ; Žiarovská, Ražná, & Labajová, ).…”

Background and objectives: A metagenomic approach was applied to analyze endophytic bacterial diversity changes in Amaranthus cruentus L. subjected to mutagenesis-based breeding. Findings: High-throughput sequencing approach of 16S rRNA variability analysis was used for monitoring of the changes of endophytic bacterial diversity in selected M generations and varieties Ficha and Pribina of Amaranthus cruentus L.A total of 15,683,430 clusters were generated in the sequencing and 15,085,381 of them passed filter. Average cluster density was 646 clusters per mm 2 . A 95%, 97% of sequences were Q >30. All sequences were classified into the 44 orders that were identified from all the analyzed genotypes of Amaranthus. Metagenomic libraries of Ficha and Pribina showed the similar profiles of identified bacterial orders and that are different from the profiles of M1 and M7 generations after gamma radiance treatment. Conclusions: Endophytic bacteria diversity was higher in the starting variety and final new variety of Amaranthus when comparing to the M generations. Based on the laboratory conditions of the growth of analyzed plant material, it supposes that endophytic bacterial abundance differences are a result of temporary changes in the amount of bacterial endophytes and the metagenomic limitation of their identification. Significance and novelty: Metagenomic analysis provides a sensitive approach that facilitates the study of the endophytic bacteria changes in the leaves of plant after gamma radiation mutagenesis.
