| the evolution of hom-c homeoboxes in the dipteran family drosophilidae. | forty-five new homeotic complex (hom-c) homeobox sequences from six species of drosophilidae (drosophila heteroneura, d. adiastola, zaprionus vittiger, chymomyza amoena, scaptodrosophila pattersoni and hirtodrosophila pictiventris) were obtained using a pcr-cloning method. these new homeoboxes are from the labial, proboscipedia, deformed, sex combs reduced, fushi tarazu, antennapedia, ultrabithorax, abdominal-a and abdominal-b genes. phylogenetic signal in the homeobox sequences was assessed and ... | 2003 | 12864914 |
| diversity of epithelial morphogenesis during eggshell formation in drosophilids. | the eggshells of drosophilid species provide a powerful model for studying the origins of morphological diversity. the dorsal appendages, or respiratory filaments, of these eggshells display a remarkable interspecies variation in number and shape, and the epithelial patterning underlying the formation of these structures is an area of active research. to extend the analysis of dorsal appendage formation to include morphogenesis, we developed an improved 3d image reconstruction approach. this app ... | 2015 | 25953345 |
