Project description:To examine how the Arabidopsis root development responds to the Rhizobium sp. IRBG74 treatment at the molecular level, we performed RNA-seq experiments. Our RNA-seq results suggest that expression of genes mainly involved in auxin signaling, cell wall and cell membrane integrity and transport is altered in response to colonization by Rhizobium sp. IRBG74.
Project description:Purpose： The goal of this study is compare the effect of phbC gene in curdlan synthesis in Agrobacterium sp. CGMCC 11546. methods: The transcriptional and metabolomics analysis the function of phbC in Agrobacterium sp. CGMCC 11546. Results:The transcriptional and metabolomics showed that the decrease of curdlan production in the ΔphbC mutants may be caused by the insufficient supply of energy ATP conclusion:phbC play an important role in curdlan synthesis in Agrobacterium sp. CGMCC 11546

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: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:We report the analysis of differentially gene expression after 7 hours and 24 hours fermentation of curdlan in Agrobacterium sp. CGMCC 11546.
Project description:In humans there are two surfactant protein A (SP-A) functional genes SFTPA1 and SFTPA2 encoding innate immune molecules, SP-A1 and SP-A2, respectively, with numerous genetic variants each. SP-A interacts and regulates many of the functions of alveolar macrophages (AM). It is shown that SP-A variants differ in their ability to regulate the AM miRNome in response to oxidative stress (OxS). Because humans have both SP-A gene products, we were interested to determine the combined effect of co-expressed SP-A1/SP-A2 (co-ex) in response to ozone (O3) induced OxS on AM miRNome. Human transgenic (hTG) mice, carrying both SP-A1/SP-A2 (6A2/1A0, co-ex) and SP-A- KO were utilized. The hTG and KO mice were exposed to filtered air (FA) or O3 and miRNA levels were measured after AM isolation with or without normalization to KO. We found: (i) The AM miRNome of co-ex males and females in response to OxS to be largely downregulated after normalization to KO, but after Bonferroni multiple comparison analysis only in females the AM miRNome remained significantly different compared to control (FA); (ii) The targets of the significantly changed miRNAs were downregulated in females and upregulated in males; (iii) Several of the validated mRNA targets were involved in pro-inflammatory response, anti-apoptosis, cell cycle, cellular growth and proliferation; (iv) The AM of SP-A2 male, shown, previously to have major effect on the male AM miRNome in response to OxS, shared similarities with the co-ex, namely in pathways involved in the pro-inflammatory response and anti-apoptosis but also exhibited differences with the cell-cycle, growth, and proliferation pathway being involved in co-ex and ROS homeostasis in SP-A2 male. We speculate that the presence of both gene products versus single gene products differentially impact the AM responses in males and females in response to OxS.
