Species-specific activation of EGF receptor signaling underlies evolutionary diversity in the dorsal appendage number of the genus Drosophila eggshells
In Drosophila melanogaster, the patterning of dorsal appendages on the eggshell is strictly controlled by EGFR signaling. However, the number of dorsal appendages is remarkably diverse among Drosophila species. For example, D. melanogaster and D. virilis have two and four dorsal appendages, respectively. Here we show that during oogenesis the expression patterns of rhomboid (rho) and argos (aos...
متن کاملDev111898 4710..4715
Drosophila eggshells display remarkable morphological diversity among species; however, the molecular origin of this structural diversification is mostly unknown. Here, we analyzed the dorsal ridge (DR), a lumen-like structure along the dorsal side of eggshells, from numerous Drosophila species. This structure varies in length and width across species, and is absent from D. melanogaster eggshel...
متن کاملMorphological diversity in three species of Chubs (Squalius spp.) populations in Iranian Basins
. In this study, morphological variation of three species of Squalius in Iranian basins was studied. For this purpose, 709 specimens were captured from the Caspian Sea, the Urmia Lake, the Namak Lake and the Tigris basin. After anesthetizing in clove oil solution and fixing in 10% neutralized formalin, specimens were transferred to the Isfahan University of Technology Ichthyology Museum (IUT-IM...
متن کاملEvaluation of species diversity and spatial distribution characteristics of five dominant plant species in Hamoon wetlands
This research aimed to investigate plant species diversity and spatial distribution of five dominant species i.e. Phragmites australis, Tamarix meyeri, Aeluropus littoralis, Aeluropus lagopoides and Cynodon dactylon in Hamoon international wetlands in 2015. To this end, a randomize-systematic sampling method was used according to w pattern by four strip transect at 5000 m2 at each station. The ...
متن کاملEvolutionary changes in gene regulation from a comparative analysis of multiple Drosophila species.
Exploiting the ortholog/homolog information now available from the complete genomic sequences of twelve species of Drosophila, we have investigated the ability of regulatory site recognition methods to find regulatory changes for orthologs linked to chromosomal rearrangements. This has made use of the wealth of synteny information among these species. By comparing orthologs in multiple species,...
