The Pristionchus pacificus genome provides a unique perspective on nematode lifestyle and parasitism
Comparison genomics analysis of three ecologically distinct nematodes offers a unique opportunity to investigate the association between genome structure and lifestyle.
Conserved and divergent expression aspects of the Drosophila segmentation gene hunchback in the short germ band embryo of the flour beetle Tribolium.
Cloned the homologue of hb from the flour beetle Tribolium and shows that, on the basis of its expression pattern, most of its functions seem to be conserved between these two species, suggesting that hb may have the same functions in early Drosophila and Tribolia development, despite the different types of embryogenesis in these twospecies.
The evolution of signalling pathways in animal development
Looking at how these pathways evolved might provide insights into how a few signalling pathways can generate so much cellular and morphological diversity during the development of individual organisms and the evolution of animal body plans.
A Conserved Endocrine Mechanism Controls the Formation of Dauer and Infective Larvae in Nematodes
Involvement of an orthologue of the Drosophila pair-rule gene hairy in segment formation of the short germ-band embryo of Tribolium (Coleoptera)
Hair belongs to the primary pair-rule genes in Drosophila which are directly regulated by the gap genes, such as Krüppel l6–13, and it is shown here that hairy is expressed in several stripes at blastoderm stage and later on in two stripes in the growth zone of the developing embryo.

Function integration of acquired cellulase genes into the nematode's biology as predicted by theory is demonstrated, suggesting functional assimilation, remarkable gene turnover and selection might represent key features of horizontal gene transfer events in nematodes.
Expression patterns of twist and snail in Tribolium (Coleoptera) suggest a homologous formation of mesoderm in long and short germ band insects.
The expression of the two zygotic target genes, twist and snail, are required for mesoderm formation both at early blastoderm stage and during germband elongation until the end of the segmental growth process in Drosophila.
