Project description:We have developed a microarray intended for use in finding all transposons in a region of interest. By selectively amplifying and hybridizing transposon flanking DNA to our array, we can localize all transposons in the region present on our TIP-chip, a dense tiling array. We have tested our technology in yeast and have been successful. Keywords: transposon insertion profiling, genomic DNA, yeast

Project description:Using a TIP-seq protocol (specifically isolating transposon insertion junctions) we determined that the Ty1 retrotransposon targets tRNA genes and, in particular, we determined that the transposon inserts into nucleosomal DNA in an asymmetric pattern.

Project description:The goal of these experiments was to define the targets of Ty3 transposition in Saccharomyces cerevisiae. Ty3 is a retroviruslike element that is found at the transcription initiation site of chromosomal tRNA genes. A Ty3 that can be induced by growth in galactose-containing medium and which was marked by an insertion of HIS3 downstream of the second open reading frame of the element (POL3) was induced to undergo transposition by plating cells onto galactose containing medium and replica-plating onto medium selective for cells that had undergone transposition. These cells were collected, DNA was extracted, and inverse PCR was performed using primers inside the Ty3 element in order to generate a library of insertion sites flanked by Illumina sequence-compatible primers.

Project description:Transposon insertion site sequencing (TIS) is a powerful tool that has significantly advanced our knowledge of functional genomics. While providing valuable insights, these applications of TIS focus on (conditional) gene essentiality and neglect possibly interesting but subtle differences in the importance of genes for fitness. Notably, data from TIS experiments can be used for fitness quantification and constructing genetic interaction maps, though this potential is only sporadically exploited. We aimed to develop a method to quantify the fitness of gene disruption mutants using data obtained from the TIS screen SATAY. This dataset was used to determine the reproducibility of the fitness estimates across biological and technical replicates of the same strain of S. cerevisiae. In addition, a mutant bem3∆ strain was utilized to compare the genetic interactions inferred from these fitness estimates with those documented in published databases. The dataset for the wild-type strain was created by transforming strain yWT01 with plasmid pBK549 and picking 4 different colonies from the transformation plate. These 4 biological replicates were then renamed to FD7, FD9, FD11 and FD12.

Project description:Transposon insertion site sequencing (TIS) is a powerful method for associating genotype to phenotype. However, all TIS methods described to date use short nucleotide sequence reads which cannot uniquely determine the locations of transposon insertions within repeating genomic sequences where the repeat units are longer than the sequence read length. To overcome this limitation, we have developed a TIS method using Oxford Nanopore sequencing technology that generates and uses long nucleotide sequence reads; we have called this method LoRTIS (Long Read Transposon Insertion-site Sequencing). This experiment data contains sequence files generated using Nanopore and Illumina platforms. Biotin1308.fastq.gz and Biotin2508.fastq.gz are fastq files generated from nanopore technology. Rep1-Tn.fastq.gz and Rep1-Tn.fastq.gz are fastq files generated using Illumina platform. In this study, we have compared the efficiency of two methods in identification of transposon insertion sites.
