(Submitter supplied) Parallels between phylogeny and ontogeny have been discussed since almost two centuries and a number of theories have been proposed to explain such patterns. Especially elusive is the so-called phylotypic stage, a phase during development where species within a phylum are particularly similar to each other. While this has formerly been interpreted as a recapitulation of phylogeny, it is nowadays thought to reflect an ontogenetic progression phase, where strong constraints on developmental regulation and gene interactions exist. more...

(Submitter supplied) One of the central issues in evolutionary developmental biology is how we can formulate the relationships between evolutionary and developmental processes. Two major models have been proposed: the 'funnel-like' model, in which the earliest embryo shows the most conserved morphological pattern, followed by diversifying later stages, and the 'hourglass' model, in which constraints are imposed to conserve organogenesis stages, which is called the phylotypic period. more...

(Submitter supplied) In order to test the hypothesis that adult hybrid misexpression results from the cascading effect of earlier-expressed developmentally important improperly regulated genes, as well as address whether Von Baer’s 3rd law (suggesting that earlier stages of development should be more similar between species than later stages) holds at the level of gene expression, we conducted whole-transcriptome Drosophila melanogaster cDNA microarray-based expression profiling of males of D. more...

(Submitter supplied) An increasing number of studies, including mutant expression profiling and comparative transcriptomic analyses, require reference RNA-seq data collections in mice. Particularly, to complement previous profiling data sets based on arrays, a full RNA-seq developmental series will be required for whole embryos. E10.5 is a key reference stage as it represents the early organogenesis stage. Here, we have performed high-throughput sequencing of total RNA form whole mice embryos at embryonic stage E10.5.

(Submitter supplied) A microarray study of sex- and gonad-biased gene expression was conducted to determine whether zebrafish demonstrate male-specific patterns consistent with those observed in other animals. We identified a large number of genes (5899) demonstrating statistical differences in transcript abundance between male and female Danio rerio. All sex-biases in gene expression were due to differences between testis and ovary, although differences between male and female body likely went undetected due to constraints imposed by study design and statistical criteria. more...

(Submitter supplied) Classical embryological studies revealed that during mid-embryogenesis vertebrates show similar morphologies. This “phylotypic stage” has recently received support from transcriptome analyses, which have also detected similar stages in nematodes and arthropods. A conserved stage in these three phyla has led us to ask if all animals pass through a universal definitive stage as a consequence of ancestral constraints on animal development. more...
