A New Reference Genome Assembly for the Microcrustacean Daphnia pulex

A New Reference Genome Assembly for the Microcrustacean Daphnia pulex

Comparing genomes of closely related genotypes from populations with distinct demographic histories can help reveal the impact of effective population size on genome evolution. For this purpose, we present a high quality genome assembly of Daphnia pulex (PA42), and compare this with the first sequenced genome of this species (TCO), which was derived from an isolate from a population with >90% r...

The ecoresponsive genome of Daphnia pulex.

We describe the draft genome of the microcrustacean Daphnia pulex, which is only 200 megabases and contains at least 30,907 genes. The high gene count is a consequence of an elevated rate of gene duplication resulting in tandem gene clusters. More than a third of Daphnia's genes have no detectable homologs in any other available proteome, and the most amplified gene families are specific to the...

A male - specific genetic map of the microcrustacean Daphnia pulex based on single sperm 1 whole - genome sequencing

A Male-Specific Genetic Map of the Microcrustacean Daphnia pulex Based on Single-Sperm Whole-Genome Sequencing.

Genetic linkage maps are critical for assembling draft genomes to a meaningful chromosome level and for deciphering the genomic underpinnings of biological traits. The estimates of recombination rates derived from genetic maps also play an important role in understanding multiple aspects of genomic evolution such as nucleotide substitution patterns and accumulation of deleterious mutations. In ...

Proposal to Sequence the Genome of Daphnia Pulex

Recent characterization of the complete genomic sequences of multiple eukaryotes and prokaryotes is rapidly increasing our ability to understand how genome structure evolves and how gene expression and individual performance is modified in response to environmental challenges. These advances hold the promise of making a direct connection between the genome and the phenotype of organisms in popu...
