DOI: 10.1002/bit.28315
Abstract: Heparosan is a crucial‐polysaccharide precursor for the chemoenzymatic synthesis of heparin, a widely used anticoagulant drug. Presently, heparosan is mainly extracted with the potential risk of contamination from Escherichia coli strain K5, a pathogenic bacterium… read more here.

Frequent variations in tandem repeats pSc200 and pSc119.2 cause rapid chromosome evolution of open-pollinated rye

DOI: 10.1007/s11032-019-1033-0
Abstract: Variation in heterochromatin is thought to play an important role in chromosome evolution in cereal rye (Secale cereale). This theory has been based on only limited numbers of sampled individuals, as it is difficult to… read more here.

Rapid neo-sex chromosome evolution and incipient speciation in a major forest pest

DOI: 10.1038/s41467-017-01761-4
Abstract: Genome evolution is predicted to be rapid following the establishment of new (neo) sex chromosomes, but it is not known if neo-sex chromosome evolution plays an important role in speciation. Here we combine extensive crossing… read more here.

DOI: 10.1093/gbe/evaa092
Abstract: For nearly a century, biologists have modeled the evolution of sex chromosomes—the genetic instructions that primarily determine whether an individual will develop into a male or female (or a certain mating type)—resulting in an impressive… read more here.

DOI: 10.1093/gbe/evab242
Abstract: Abstract Birds in the clade Palaeognathae, excluding Tinamiformes, have morphologically conserved karyotypes and less differentiated ZW sex chromosomes compared with those of other birds. In particular, the sex chromosomes of the ostrich and emu have… read more here.

DOI: 10.1093/gbe/evy163
Abstract: Abstract Recombination arrest is a necessary step for the evolution of distinct sex chromosomes. Structural changes, such as inversions, may represent the mechanistic basis for recombination suppression and comparisons of the structural organization of chromosomes… read more here.

ZW sex-chromosome evolution and contagious parthenogenesis in Artemia brine shrimp
Sign Up to like & getrecommendations! Published in 2022 at "Genetics"
DOI: 10.1093/genetics/iyac123
Abstract: Eurasian brine shrimp (genus Artemia) have closely related sexual and asexual lineages of parthenogenetic females, which produce rare males at low frequencies. Although they are known to have ZW chromosomes, these are not well characterized,… read more here.

DOI: 10.1098/rstb.2020.0097
Abstract: Until recently, the field of sex chromosome evolution has been dominated by the canonical unidirectional scenario, first developed by Muller in 1918. This model postulates that sex chromosomes emerge from autosomes by acquiring a sex-determining… read more here.

DOI: 10.1098/rstb.2021.0314
Abstract: Sex chromosomes are familiar to most biologists since they first learned about genetics. However, research over the past 100 years has revealed that different organisms have evolved sex-determining systems independently. The differences in the ages… read more here.
