Population 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 کاملEye movements in Daphnia pulex (De Geer).
1. The various types of eye movement exhibited by the cyclopean eye of Daphnia pulex were studied using high speed motion photography. 2. This rudimentary eye, which consists of only 22 ommatidia, can move through approximately 150 degrees in the sagittal plane and 60 degrees in the horizontal plane. 3. Four classes of eye movement were found: (1) a high speed tremor at 16 Hz with an amplitude ...
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 کاملControlling proteome degradation in Daphnia pulex.
An attempted proteomic study of Daphnia pulex response to sodium chloride exposure revealed an unexpected result: very strong proteome degradation previously observed in D. pulex is halted when animals have been exposed to elevated salinity prior to protein extraction. Further characterization of conditions controlling proteome degradation shows that the proteolytic factor(s) is/are present in ...
متن کاملPromoter Architecture and Sex-Specific Gene Expression in Daphnia pulex.
Large-scale transcription start site (TSS) profiling produces a high-resolution, quantitative picture of transcription initiation and core promoter locations within a genome. However, application of TSS profiling to date has largely been restricted to a small set of prominent model systems. We sought to characterize the cis-regulatory landscape of the water flea Daphnia pulex, an emerging model...
