Project description:Cassava mosaic disease (CMD) suppresses cassava yields across the tropics. It has been reported that landraces lose CMD resistance after regeneration through de novo morphogenesis. We sequenced WGBS data of 14 samples.
Project description:We applied whole genome bisulfite Sequencing data and profiled genome-wide DNA methylation distribution in four germ cell types during spermatogenesis.
Project description:The development of whole-genome bisulfite sequencing (WGBS) has led to a number of exciting discoveries about how genomes utilize DNA methylation and has led to a plethora of novel testable hypotheses. Methods for constructing sodium bisulfite-converted and amplified libraries have recently excelled to the point that the bottleneck for experiments that use WGBS has shifted to data analysis and interpretation. Here we present empirical evidence for an over-representation of methylated DNA from WGBS. This enrichment for methylated DNA is exacerbated by higher cycles of PCR and is influenced by the type of uracil-insensitive DNA polymerase used for amplifying the sequencing library. Future efforts to computationally correct for this enrichment bias will be essential to increasing the accuracy of determining methylation levels for individual cytosines.

Project description:In this study, we generated whole genome bisulfite sequencing data 3 tissues in Holstein cattle. We analyzed the variations of DNA methylation among tissues.
