Project description:Plant microRNAs (miRNAs) have emerged as important regulators in developmental processes and stress responses in plants. To identify the wound-responsive miRNAs in the leaves of sweet potato, small RNA deep sequencing was conducted on unwounded and wounded leaves (30 min). Total RNAs were isolated for library construction and analyzed by RNA-sequencing via Illumina Genome Analyzer IIx platform. About 16 million total reads were obtained for each sample.
Project description:<p>Heat stress is an important issue in dairy cattle feeding management affecting summer health and economic efficiency. In recent years, global climate change has led to an increase in atmospheric CO2 content and average daily temperature, making heat stress a major challenge in dairy farming. This experiment combined 16S rDNA sequencing, metagenomic sequencing and metabolomic analysis. In this experiment, 10 cows each of growing heifers, heifers and lactating cows were selected for sample collection in April and August. Ruminal fluid was collected and filtered through gauze, which was immediately transferred to liquid nitrogen prior to macrogenomic, 16S rDNA sequencing and metabolomic analyses.</p>
Project description:4C procedure was used for analysis of genomic contacts of rDNA units in HEK 293T cells. The primers for 4C were selected inside IGS. Our data indicate that mostly rDNA units exhibit close proximity with pericentromeric regions in different chromosomes. We also detected the contacts within a rDNA unit and between rDNA units. Examination of rDNA genome-wide contacts in HEK 293T cells using 4C approach.
Project description:We compared the microbiota of paired mouse caecal contents and faeces by applying a multi-omic approach, including 16S rDNA sequencing, shotgun metagenomics, and shotgun metaproteomics. The aim of the study was to verify whether faecal samples are a reliable proxy for the mouse colonic luminal microbiota, as well as to identify changes in taxonomy and functional activity between caecal and faecal microbial communities, which have to be carefully considered when using stool as sample for mouse gut microbiota investigations.
