A microsatellite-based genetic linkage map of the waterflea, Daphnia pulex: On the prospect of crustacean genomics.
We describe the first genetic linkage map for Daphnia pulex using 185 microsatellite markers, including 115 new markers reported in this study. Our approach was to study the segregation of polymorphisms in 129 F2 progeny of one F1 hybrid obtained by crossing two genetically divergent lineages of Daphnia isolated from two Oregon populations. The map spanned 1206 Kosambi cM and had an average int...
متن کاملThe 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...
متن کاملPopulation Genomics of Daphnia pulex.
Using data from 83 isolates from a single population, the population genomics of the microcrustacean Daphnia pulex are described and compared to current knowledge for the only other well-studied invertebrate, Drosophila melanogaster These two species are quite similar with respect to effective population sizes and mutation rates, although some features of recombination appear to be different, w...
متن کاملActivation of the Ephippial Egg of Daphnia pulex
The ephippial eggs of Daphnia pulex require light for the initiation of development. The ephippial capsule prevents the completion of development but is not a barrier to an adequate light stimulus. Working with decapsulated eggs, the response to light increased to 100 % within 9 days of storage in the dark and remained at 100% for up to 60 days of storage in the dark. The response was not depen...
