...in ditelosomic chromosomes from wheat homoeologous groups 1 (A), 6 (B), and 7 (C). Each subpanel displays multiple tracks: the top track marks the centromeric regions based on CENH3 ChIP-seq signals. The next four tracks show normalized resequencing coverage (reads per genomic content, RPGC) in 10-bp bins...

...). We investigate the genomic organization of the MHC region, ontogenetic and tissue-specific expression profiles, and the evolutionary history of the MHC gene family. To achieve this, we integrated publicly available chromosome-scale assemblies from four newt species with newly generated long...

.... By aligning the sequencing data of L. oculatus and A. spatula to Chromosome 3 of A. spatula, we found that, at the fusion region, the sequencing depth of a 2-kb fragment in L. oculatus was zero, whereas A. spatula showed a relatively high sequencing depth in the fusion region. Further genomic feature analysis...

...or increased percentage of diapause occurrence, respectively. To determine the genomic distribution of DNA methylation and histone modifications (specifically H3K9me3 and H3K27me3) in the heads of the Asian corn borer, we used whole- bisulfite sequencing (WGBS) and ChIP-seq analysis, respectively. The analysis...
