Taxonomic classification of the bacterial endosymbiont based on next-generation sequencing: is there molecular evidence for its presence in tardigrades?

We used high-throughput sequencing of 16S rRNA to test whether tardigrade species are infected with parasites. We applied SILVA and Greengenes databases that allowed taxonomic classification of bacterial sequences to OTUs. The results obtained from both databases differed considerably in the number of OTUs, and only the Greengenes database allowed identification of (infection was also supported by comparison of sequences to NCBI database).

Microenvironmental Interplay Predominated by Beneficial Abates Fungal Pathogen Incidence in Paddy Environment.

Rice fungal pathogens, responsible for severe rice yield loss and biotoxin contamination, cause increasing concerns on environmental safety and public health. In the paddy environment, we observed that the asymptomatic rice phyllosphere microenvironment was dominated by an indigenous fungus, , which positively correlated with alleviated incidence of , one of the most aggressive plant pathogens. Through the comparative metabolic profiling for the rice phyllosphere microenvironment, two metabolites were assigned as exclusively enriched metabolic markers in the asymptomatic phyllosphere and increased remarkably in a population-dependent manner with .

Effect of Exogenous Application of Methyl Jasmonate on the Lipid and Carbohydrate Content and Composition of Winter Triticale ( Triticosecale Wittm.) Grain and the Severity of Fungal Infections in Triticale Plants and Grain.

Kernels of winter triticale ( Triticosecale Wittm. cv. Dinaro) were analyzed.

Effect of jasmonic acid-methyl ester on the composition of carbohydrates and germination of yellow lupine (Lupinus luteus L.) seeds.

Mature seeds of yellow lupine contained sucrose, raffinose family oligosaccharides (RFOs), and galactosyl cyclitols as major soluble carbohydrates. The study showed that RFOs dominated in lupine seeds (16% DW). The disappearance of both types of alpha-d-galactosides in germinating lupine seeds was strongly inhibited by the presence of jasmonic acid-methyl ester (JA-Me) at a concentration of 10(-3)M in the incubation medium.
