Rapid Expansion and Functional Divergence of Subtelomeric Gene Families in Yeasts

Rapid Expansion and Functional Divergence of Subtelomeric Gene Families in Yeasts

BACKGROUND Subtelomeres, regions proximal to telomeres, exhibit characteristics unique to eukaryotic genomes. Genes residing in these loci are subject to epigenetic regulation and elevated rates of both meiotic and mitotic recombination. However, most genome sequences do not contain assembled subtelomeric sequences, and, as a result, subtelomeres are often overlooked in comparative genomics. ...

Functional divergence and age distribution of vertebrate gene families

In this paper, we explore the pattern of Type I functional divergence (i.e., altered functional constraints or site-specific rate difference) in the caspase gene family that is important for apoptosis (programmed cell death) and cytokine maturation. By taking advantage of substantial experimental data of caspases, the functional/structural basis of our posterior predictions from sequence analys...

Rapid divergence and expansion of the X chromosome in papaya.

X chromosomes have long been thought to conserve the structure and gene content of the ancestral autosome from which the sex chromosomes evolved. We compared the recently evolved papaya sex chromosomes with a homologous autosome of a close relative, the monoecious Vasconcellea monoica, to infer changes since recombination stopped between the papaya sex chromosomes. We sequenced 12 V. monoica ba...
