Article
Open AccessHomeobox oncogene activation by pan-cancer DNA hypermethylation
Cancers have long been recognized to be not only genetically but also epigenetically distinct from their tissues of origin. Although genetic alterations underlying oncogene upregulation have been well studied,...

Article
Open AccessDNA epigenome editing using CRISPR-Cas SunTag-directed DNMT3A
DNA methylation has widespread effects on gene expression during development. However, our ability to assign specific function to regions of DNA methylation is limited by the poor correlation between global pa...

Article
Open AccessCo-localization of major quantitative trait loci for pod size and weight to a 3.7 cM interval on chromosome A05 in cultivated peanut (Arachis hypogaea L.)
Cultivated peanut (Arachis hypogaea L.), an important source of edible oil and protein, is widely grown in tropical and subtropical areas of the world. Genetic improvement of yield-related traits is essential for...
-
Article
Open AccessGenomic survey sequencing for development and validation of single-locus SSR markers in peanut (Arachis hypogaea L.)
Single-locus markers have many advantages compared with multi-locus markers in genetic and breeding studies because their alleles can be assigned to particular genomic loci in diversity analyses. However, ther...
