Project description:Oak galls form when gall wasps lay their eggs into part of the tree; in some galls, this attachment point to the host consists of only a few cells. The gall itself comprises entirely of host tissue; however, the initiation, development, and physical appearance are controlled by the inducer. This raises the intriguing question of the molecular mechanisms underlying gall formation, by which one or a small number of cells are reprogrammed and commit to a novel developmental path. Gall wasps undergo two generations each year, and the galls formed by these two generations exhibit markedly different appearances. We sequenced the transcriptomes of both the sexual and asexual generations of Neuropterus quercusbaccarum and Neuroterus numismalis. The transcriptomes of the generations that occur at the same time of year are more similar to each other than they are to the opposite generation of their respective species.

Project description:We sequenced DNA from a bulk of Col x Ler F2 hybrid plants (WT and recq4) using Nanopore long-read sequencing and identified crossover sites with COmapper. For nanopore sequencing of gDNA from 1,000 pooled seedlings, 10-day-old seedlings were ground in liquid nitrogen using a mortar and pestle. The ground tissue was resuspended in four volumes of CTAB buffer (1% [w/v] CTAB, 50 mM Tris-HCl pH 8.0, 0.7 M NaCl, 10 mM EDTA) and incubated at 65°C for 30 min. Following chloroform extraction, isopropanol precipitation and removal of RNAs as above, the gDNA pellet was resuspended in 150 μl TE (10 mM Tris-HCl pH 8.0, 0.1 mM EDTA) buffer and gDNA was quantified using a Qubit dsDNA Broad Range assay kit (Thermo Fisher, Q32853). Nine micrograms of gDNA from pollen or seedlings was used to construct a nanopore long-read sequencing library using a Ligation Sequencing Kit V14 (Nanopore, SQK-LSK114). The libraries were sequenced using a PromethION platform (BGI, Hong Kong).

Project description:We sequenced DNA from the leaves of ten Col x Ler F1 hybrid plants (WT and recq4) using Nanopore long-read sequencing and identified crossover sites with COmapper. These data were used as a negative control for COmapper, as no crossover sites were expected to be detected. For nanopore sequencing of gDNA from leaves, leaves from 10 5-week-old plants were ground in liquid nitrogen using a mortar and pestle. The ground tissue was resuspended in four volumes of CTAB buffer (1% [w/v] CTAB, 50 mM Tris-HCl pH 8.0, 0.7 M NaCl, 10 mM EDTA) and incubated at 65°C for 30 min. Following chloroform extraction, isopropanol precipitation and removal of RNAs as above, the gDNA pellet was resuspended in 150 μl TE (10 mM Tris-HCl pH 8.0, 0.1 mM EDTA) buffer and gDNA was quantified using a Qubit dsDNA Broad Range assay kit (Thermo Fisher, Q32853).

Project description:Genomic DNA from 55 wild type Col x Ler F2 individuals was extracted using the CTAB method. Equal amounts of DNA from these 55 plants were pooled into two groups (pool 1 = 4 plants; pool 2 = 51 plants), and nine micrograms of gDNA from each pool was used to generate Nanopore sequencing libraries with the Ligation Sequencing Kit V14 (Nanopore, SQK-LSK114). The libraries were sequenced independently using PromethION (BGI, Hong Kong).

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.
