of the bacterial communities (Bray-Curtis dissimilarities) (Sokal and Michener, 1958) were characterized using principal coordinate analysis (PCoA) and the unweighted pair-group method with arithmetic mean (UPGMA) clustering based on unweighted UniFrac distances. The unweighted Uni- Frac (UUF, qualitative measure) assesses the presence or absence of taxa and is, thus, more sensitive to rare... South Korea and microbiome analysis was performed to analyze bacterial communities in- cluding Acidovorax species community. Next generation sequencing (NGS) was performed by extracting genom- ic DNA from 92 soil samples from 8 different provinces using a fast genomic DNA extraction kit. NGS data analysis results revealed that, total, 39,367 operational taxonomic unit (OTU), were obtained. NGS data results revealed that, most dominant phylum in all the soil samples was Proteobacteria (37.3%). In... -

fire blight infected apple. (A) Relative abundance in family level. Family level was cut off in top 10 taxa. (B) Principal coordinates analysis (PCoA) to visualize similarities or dissimilarities based on Bray-Curtis distance. Polygon zone is automatically enclosed points. Statistical analysis conducted by permutational analysis of variance and appeared significant difference between samples (P... Fire blight disease, caused by Erwinia amylovora, could damage rosaceous plants such as apples, pears, and raspberries. In this study, we designed to understand how E. amylovora affected other bacterial communities on apple rhizosphere; twig and fruit endosphere; and leaf, and fruit episphere. Limited studies on the understanding of the microbial community of apples and changes the community structure by occurrence of the fire blight disease were conducted. As result of these experiments, the... -

of the in STRUC- TURE 2.3.4 software (Porras-Hurtado et al., 2013). The main coordinate analysis (principal coordinate anal- ysis, PCoA), using Dice distance, was performed to repre- sent the distances between the group of isolates from the same locations in GeneAIEx v.6.4 (Peakall and Smouse, 2012). Results The tested Bga isolates from two populations collected in 2014 and 2015 showed a high... The purpose of this study was to determine the viru- lence structure of oat powdery mildew (Blumeria grami- nis f. sp. avenae, Bga) populations in Poland collected in 2014 and 2015. Powdery mildew isolates were collected from 18 locations in Poland. In total, nine lines and cultivars of oat, with different mildew resistance genes, were used to assess virulence of 180 isolates. The results showed that a significant proportion of the Bga isolates found in Poland were virulent to differentials with... -

Principal coordinates analysis (PCoA) based on Bray-Curtis distance. Sap and rhizosphere samples (A) and sap samples (C) only at the operational taxonomic units (OTUs) level show theirs distance of fungal and bacterial composition similarity. Dots representing OTUs for sap and rhizosphere (B) and sap only sample (D) show that each OTU closer to the sample position in PCoA contributes more. The... Understanding the microbial community and function are crucial knowledge for crop management. In this study, bacterial and fungal community structures both rhizosphere and endosphere in kiwifruit were analyzed to gain our knowledge in kiwifruit microbiome. Microbial community in rhizosphere was less variation than endosphere community. Functional prediction results demonstrated that abundance of saprotrophic fungi was similar in both rhizosphere and endosphere, but potential pathogenic fungi was... -

factors such as temperature, wind, wind and humidity or biotic factors such as bees and other plants (Obersteiner et al., 2016). When their similarities were also shown in Principal coordinate analysis (PCoA), NZ and CN had a correlation but KR13 and KR14 became less relevant as they had changed the bacterial di- versity (data not shown). Top 20 OTUs more abundant in the imported than the... Flowers of kiwifruit are morphologically hermaphroditic and survivable binucleate pollen is produced by the male flowers. In this study, we investigated microbial diversity in kiwifruit pollens by analyzing amplicon sequences of 16S rRNA. Four pollen samples were collected: ‘NZ’ was imported from New Zealand, ‘CN’ from China in year of 2014, respectively. ‘KR13’ and ‘KR14’ were collected in 2013′ and 2014′ in South... -

seen with B-diversity analysis by PCoA. Microbial community at zero time, in both the soils (Wk0-ctrl and Wk0-48), were similar to each other according to Bray-Curtis dissimilarity index, suggesting the shift in microbial community by P. fluorescens pc78-48 treatment. Discussion Development of molecular biological techniques makes it possible to construct the gene probing tools for analysis... Pseudomonas fluorescens pc78 is an effective biocontrol agent for soil-borne fungal diseases. We previously constructed a P43-gfp tagged biocontrol bacteria P. fluorescens pc78-48 to investigate bacterial traits in natural ecosystem and the environmental risk of genetically modified biocontrol bacteria in tomato rhizosphere. Fluctuation of culturable bacteria profile, microbial community structure, and potential horizontal gene transfer was investigated over time after the bacteria treatment to... -

to their genetic dissimilarity using the agglomera- tive hierarchical clustering (AHC) method. Analysis was ..PAGE:5 Goral et al. 230 performed by means of the UPGMA (Unweighted pair group method with arithmetic mean) and Ward algorithms. Multivariate principal coordinate analysis (PCoA) was also applied for grouping of wheat cultivars. Analysis of variance of FHB index and Fusarium dam- aged... was analysed. Grain samples originated from plants inoculated with Fusarium culmorum and naturally infected with Fusarium species. The genetic distance between the tested cultivars was determined and data were analysed using multivariate data analysis methods. Genetic dissimilarity of wheat cultivars ranged between 0.06 and 0.78. They were grouped into three distinct groups after cluster analysis of genetic distance. Wheat cultivars differed in resistance to spike and kernel infection and in... -
