Project description:Purpose:first,we want to find the genes revelant to curdlan synthesis and oxygen regulation, second, we want to research the function of fnrN gene in Agrobacterium sp. ATCC 31749. Method: samples of cell growth phase, curdlan-producing phase (normoxia) and curdlan-producing phase (micro-oxygen treated) in both Agrobacterium sp. ATCC 31749 wild strain and ΔfnrN strain were collectecd to extract mRNA. Each sample was treated in duplicate. The softwares we used include fastqc, trimmomatic, TopHat2 and Cufflinks. Illumina Hiseq4000 was used to complete the research.
Project description:Gene Expression Analysis of Curdlan Production in Agrobacterium sp. ATCC 31749 Two conditions are compared with four biological replicates of each condition, corresponding to eight total samples. The control condition was sampled at 22 hours during the exponential growth phase when no curdlan is produced. The second condition was sampled at 70 hours after the initiation of curdlan production, corresponding to approximately 100 hours.
Project description:S. aureus ATCC 25923 is performance standard for antimicrobial susceptibility testing. S. aureus ATCC 33591 showed resistance against erytrhromycin, penicillin, and streptomycin. We used microarray to compare RNA expression between sensitive and resistant strain of S. aureus as a preliminary research for MRSA inhibition.
Project description:We report the Assay for Transposase-Accessible Chromatin with sequencing (ATAC-seq) for high-throughput profiling of accessible chromatin regions after cold treatment in Vitis amurensis
Project description:Bud endodormancy induction response of two genotypes (Seyval, a hybrid white wine grape and Vitis riparia, PI588259, a native North American grape species) was compared under long (15 h) and short (13 h) photoperiods. Proteins were extracted from both genotypes for all time points and experimental conditions. The proteins were separaed by 2D-PAGE, trypsin digested, and the peptides identified with a MALDI-TOF-TOF mass spectrometer. A master gel was made and mapped with all proteins from both genotypes. The proteins were identified by matching the peptide sequences against the 8X Vitis vinifera grape genome in NCBI. This study was funded by NSF grant DBI064755 and is the result of a collaboration between Dr. Anne Fennell at South Dakota State University and Dr. Grant R. Cramer at the University of Nevada, Reno.
