The article offers information on a study conducted by the authors related to analysis of chromosomal locations of the rRNAs and histone H3 genes in scarabaeinae beetles to understand their chromosomal organization. It states that the 18S rRNA gene sites were either located on sex chromosomes or autosomes or both. It mentions that comparison of rDNa sites and quantity of heterochromatin showed that species presenting heterochromatin were restricted to centromeric/pericentromeric region.

    In this study we show that loss-of-function alleles of the JIL-1 histone H3S10 kinase act as enhancers of position-effect variegation at pericentric sites whereas the gain-of-function JIL-1Su(var)3-1[3] allele acts as a suppressor strongly supporting a functional role for JIL-1 in maintaining...

    In mammals X inactivation is initiated by expression of Xist RNA and involves the recruitment of Polycomb repressive complex 1 (PRC1) and 2 (PRC2), which mediate chromosome-wide ubiquitination of histone H2A and methylation of histone H3, respectively. Here, we show that PRC1 recruitment by Xist...
