Expression data from three rice lines (1-control, 1-transgenic and 1-negative segregant) throughout generations and under salt stress

ABSTRACT: The approval of genetically modified (GM) crops is preceded by years of intensive research to demonstrate safety to humans and environment. We recently showed that in vitro culture stress is the major factor influencing proteomic differences of GM vs. non-GM plants. This made us question the number of generations needed to erase such memory. We also wondered about the relevance of alterations promoted by transgenesis as compared to environment-induced ones. Here we followed three rice lines (1-control- C, 1-transgenic- Ta and 1-negative segregant- NSb) throughout eight generations after transgenesis, and further analyzed their response to salinity stress on the F6 generation.

Expression data from three rice lines (1-control, 1-transgenic and 1-negative segregant) throughout generations and under salt stress

Project description:The approval of genetically modified (GM) crops is preceded by years of intensive research to demonstrate safety to humans and environment. We recently showed that in vitro culture stress is the major factor influencing proteomic differences of GM vs. non-GM plants.

Here we followed three rice lines (1-control- C, 1-transgenic- Ta and 1-negative segregant- NSb) throughout eight generations after transgenesis, and further analyzed their response to salinity stress on the F6 generation. Three pools of 10 whole fifteen days-old rice seedlings (Oryza sativa L. ssp. japonica cv. Nipponbare) were selected from each line at F4, F6 and F8 generations. Because salinity stress was imposed on half of the seedlings (C, Ta and NSb) in F6 generation, from this generation onwards we worked with six rice lines (C, Csalt, Ta, Tasalt, NSb, NSbsalt).

Bulk segregant analysis of 3D growth defective mutant in Physcomitrella patens (nog2)

Project description:This project aimed to discover genes that regulate the transition from 2D to 3D growth in the moss Physcomitrella patens. Mutants were generated that do not pattern 3D growth. Bulk segregant analysis was conducted to identify the causative genes. This experiment contains two samples - WT-pool, Mt-pool.

Bulk segregant analysis of 3D growth defective mutant in Physcomitrella patens (Vx501).

Project description:This project aimed to discover genes that regulate the transition from 2D to 3D growth in the moss Physcomitrella patens. Mutants were generated that failed to initiate 3D growth. Bulk segregant analysis was conducted to identify the causative genes. This experiment contains four samples - GdGFP, VxmCherry, WT-pool, Mt-pool.

Determining single-cell mRNA expression profiles of a specific population isolated from zebrafish embryos at 10 hours post fertilization

Project description:Stable zebrafish cell lines were created that expressed GFP under the control of a previously characterized mouse Smarcd3 enhancer (10.7554/eLife.03848). Specifically, the 2.7 kb Mouse Smarcd3-F6 sequence (chr5: 24113559 -24116342 from mm9 assembly) was sub-cloned from a gateway entry vector into the Zebrafish Enhancer Detection (ZED). Tol2-mediated transgenesis was performed and stable lines were created. The Smarcd3-F6:EGFPhsc70 allele was used for all genomics experiments. Smarcd3-F6:EGFPhsc70 embryos were dissociated at 10 hours post fertilization for fluorescent activated cell sorting (FACS) to collect GFP+ cells. Single-cell cDNA libraries were prepared using Fluidgim C1 system ((Fluidgim, PN 100-7168 Rev. B1)). 96 single-cell libraries were collected from three batches of experiments and sequenced on the Illumina HiSeq 2500 platform. Data from 92 cells (number of genes detected > 2000) were kept for clustering analysis. For the tube control experiments we performed mRNA-seq on ~4000 cells from the same embryo batches as the scRNA-seq experiments. GFP negative cells were also included to enable a GFP+ versus GFP- comparison. Libraries were made following the Fluidgim C1 mRNA-seq tube control protocol (Fluidgim, PN 100-7168 Rev. B1). Polyadenylated mRNA was captured by Oligo-dT primers and PCR amplified after reverse transcription. Final sequencing libraries were made using Nextera XT DNA Sample Preparation Kit and pair-end sequenced on the Illumina HiSeq 2500 platform.

Fast forward genetics: mutation mapping and identification using next-generation sequencing and enrichment of bulk segregant pools

Project description:Phenotype-driven forward genetic experiments are among the most powerful approaches for linking biology and disease to genomic elements. Although widely used in a range of model organisms, positional cloning of causal variants is still a very laborious process. Here, we describe a novel universal approach, named fast forward genetics that combines traditional bulk segregant techniques with next-generation sequencing technology and targeted genomic enrichment, to dramatically improve the process of mapping and cloning multiple mutants in a single experiment. In a two-step procedure the mutation is first roughly mapped by ‘light’ sequencing of the bulk segregant pool, followed by genomic enrichment and deep-sequencing of the mutant pool for the linked genomic region. The latter step allows for simultaneous fine-mapping and mutation discovery. We successfully applied this approach to three Arabidopsis mutants, but the method can in principle be applied to any model organism of interest and is largely independent of the genome size. Moreover, we show that both steps can be performed in multiplex using barcoded samples, thereby increasing efficiency enormously.

The plant hormone auxin triggers distinct phosphorylation responses in the two different generations of the fern Ceratopteris richardii

Project description:The fern Ceratopteris richardii has two distinct generations: the haploid gametophyte and diploid sporophyte, which resembles the difference between the major land plant clades of bryophytes and tracheophytes. We profiled the fast auxin-dependent phosphorylation response in both generations to identify the shared evolutionary targets and differences between the two generations
