    [Abstract]

    CRISPR/Cas9 is an established and flexible tool for genome editing. However, most methods used to generate expression clones for the CRISPR/Cas9 are time-consuming. Hence, we have developed a one-step protocol to introduce sgRNA expression cassette(s) directly into binary vectors (Liu et al., 2020). In this approach, we have optimized the

    Dual sgRNA-based Targeted Deletion of Large Genomic Regions and Isolation of Heritable Cas9-free Mutants in Arabidopsis

    [Abstract] CRISPR/Cas9 system directed by a gene-specific single guide RNA (sgRNA) is an effective tool for genome editing such as deletions of few bases in coding genes. However, targeted deletion of larger regions generate loss-of-function alleles that offer a straightforward starting point for functional dissections of genomic loci. We present an ...
    Methylation-sensitive Amplified Polymorphism as a Tool to Analyze Wild Potato Hybrids
    利用甲基化敏感扩增多态性分析野生马铃薯杂交种

    [Abstract] Methylation-Sensitive Amplification Polymorphism (MSAP) is a versatile marker for analyzing DNA methylation patterns in non-model species. The implementation of this technique does not require a reference genome and makes it possible to determine the methylation status of hundreds of anonymous loci distributed throughout the genome. In addition, ...
    Genome-wide Estimation of Evolutionary Distance and Phylogenetic Analysis of Homologous Genes
    进化距离的全基因组评估和同源基因的系统进化分析

    [Abstract] Homologous genes, including paralogs and orthologs, are genes that share sequence homologies within or between different species. Homologous genes originate from a common origin through speciation, genetic duplication or horizontal gene transfer. Estimation of the sequence divergence of homologous genes help us to understand divergence time, which ...
