Dynamic karyotype evolution and unique sex determination systems in Leptidea wood white butterflies [PDF]
, 1943 [Background] Chromosomal rearrangements have the potential to limit the rate and pattern of gene flow within and between species and thus play a direct role in promoting and maintaining speciation.

Oligo-barcode illuminates holocentric karyotype evolution in Rhynchospora (Cyperaceae)
Frontiers in Plant ScienceHolocentric karyotypes are assumed to rapidly evolve through chromosome fusions and fissions due to the diffuse nature of their centromeres. Here, we took advantage of the recent availability of a chromosome-scale reference genome for Rhynchospora ...

Evidence of hermaphroditism and sex ratio distortion in the fungal feeding nematode Bursaphelenchus okinawaensis [PDF]
, 2014 Nematodes have many different reproductive strategies along with their divergent life-histories; the ability of hermaphrodite to self- and cross-fertilize is useful for genetic manipulation.

Cell Reports, 2016 The stability of the genome is paramount to organisms. However, diverse eukaryotes carry out programmed DNA elimination in which portions or entire chromsomes are lost in early development or during sex determination.

H3K56me3 is a novel, conserved heterochromatic mark that largely but not completely overlaps with H3K9me3 in both regulation and localization. [PDF]
, 2013 Histone lysine (K) methylation has been shown to play a fundamental role in modulating chromatin architecture and regulation of gene expression. Here we report on the identification of histone H3K56, located at the pivotal, nucleosome DNA entry/exit ...

Chromosome and genome size variation in Luzula (Juncaceae), a genus with holocentric chromosomes
, 2012 The present study examines chromosome and genome size evolution in Luzula (woodrush; Juncaceae), a monocot genus with holocentric chromosomes. Detailed karyotypes and genome size estimates were obtained for seven Luzula spp., and these were combined with additional data from the literature to enable a comprehensive cytological analysis of the genus. So

Identification and chromosomal localization of mariner-like elements in the cabbage moth Mamestra brassicae (Lepidoptera) [PDF]
, 2003 A complete mariner-like element has been identified in the lepidopteran Mamestra brassicae. This element, called Mbmar, represents a new type of mariner transposon.

The outer kinetochore protein KNL-1 contains a defined oligomerization domain in nematodes [PDF]
, 2014 The kinetochore is a large, macromolecular assembly that is essential for connecting chromosomes to microtubules during mitosis. Despite the recent identification of multiple kinetochore components, the nature and organization of the higher order ...
