Whole-genome DNA methylation analysis in hydrogen peroxide overproducing transgenic tobacco

Project description:We compared the level of methylated cytosines between hydrogen peroxide overproducing (L8) and azygotes (L1) tobacco plants. We generated single base resolution maps of DNA methylation by whole genome bisulfite sequencing for 6-week-old plants from both transgenic tobacco lines. In total, we found 4,765 and 4,667 hyper and hypomethylated cytosines, respectively. These DmCs were associated with different regions of the genome, resulting in 1034 genes with at less one DMCs. 83 of these 1034 genes also showed differential expression. In this set of genes we found some correspond to proton transport, such as the V-type proton ATPase, and the ABC transporter. Our results corroborate that H2O2, as part of the balance of reactive oxygen species, plays a key role in the physiological adaptation of plants mediated by the methylation regulation.

Transcriptome expression of W38 and transgenic tobacco overexpressing IbTLD treating with/without hydrogen peroxide

Transcriptome expression of W38 and transgenic tobacco overexpressing IbTLD treating with/without hydrogen peroxide

Project description:To understand regulation mechanism of IbTLD, transcriptomes of W38 and trangenic tobacco overexpressing IbTLD with/withouthydrogen peroxide were dissected. 12-day-old seedlings were treated with10 mM H2O2 for 6 hrs. Total RNAs were isolated for library construction and analyzed by RNA-seq via Solexa platform. Raw sequences were obtained from the Illumina Pipeline software bcl2fastq v2.0 and expected to generate 20M (million reads or Gb) per sample.

Hydrogen peroxide stress and Zat12 over-expression in Arabidopsis.

Project description:In this experiment we tested the transcriptome of transgenic Arabidopsis seedlings (5-day-old) constitutively expressing the zinc-finger protein Zat12 (At5g59820) under the control of the 35S-CaMV promoter (Zat12). The transcriptome of these seedlings was compared to that of wild type seedlings grown under the same conditions (WT) and to that of wild type seedlings grown under the same conditions and subjected to a hydrogen peroxide stress (WT+H2O2). Hydrogen peroxide treatment was performed by applying 20 mM hydrogen peroxide for 1 hour. In parallel to these experiments transgenic plants expressing Zat12 were subjected to a similar hydrogen peroxide stress (Zat12+H2O2). All treatments were performed with similar size and age seedlings grown in liquid culture (MS) and sampled at the same time as described by Davletova et al., 2005.

Response of Bacillus pumilus to hydrogen peroxide

Project description:Reactive oxygen species such as hydrogen peroxide occur in all aerobically living organisms. Oxidative stress during fermentation can impair the fitness of the production host and the quality of the product. B. pumilus has been described as highly resistant to hydrogen peroxide. The response of exponentially growing B. pumilus cells to hydrogen peroxide was studied.

Adaptation to hydrogen peroxide

Project description:Adaptation to hydrogen peroxide in Saccharomyces cerevisiae is profiled with expression arrays. Adaptation describes the process in which a mild dose of toxin (in this case, hydrogen peroxide) is able to protect against a later acute dose. Here, we study two adaptive protocols (0.1 mM H2O2 and 0.1 + 0.4 mM H2O2) and one acute protocol (0.4 mM H2O2) to identify processes uniquely involved in adaptation. Predictions from these studies are validated in expression profiling of deletion mutants of the transcription factors Yap1, Mga2, and Rox1.
