Ortholog-Finder: A Tool for Constructing an Ortholog Data Set
Orthologs are widely used for phylogenetic analysis of species; however, identifying genuine orthologs among distantly related species is challenging, because genes obtained through horizontal gene transfer (HGT) and out-paralogs derived from gene duplication before speciation are often present among the predicted orthologs. We developed a program, "Ortholog-Finder," to obtain ortholog data set...
متن کاملPut that hunchback over here
Cristae in crisis ristae, the complex involutions of the mitochondrial inner membrane, vastly increase the surface area across which ATP synthase can generate a proton gradient. Now, new findings from Jean Velours (Université Victor Ségalen, Bordeaux, France) and colleagues suggest that ATP synthase may be important in forming cristae in the first place. Velours' theory is that oligomerization ...
متن کاملAssociation of rhizobia with a marine polychaete.
We report the presence of Mesorhizobium, a genus best known for its nitrogen-fixing symbiosis with terrestrial legumes, associated with the marine polychaete Meganerilla bactericola (Annelida: Nerillidae). Abundant epibionts were previously described as coating the exterior of M. bactericola, which is found within the anoxic sulfide-oxidizing microbial mats of the Santa Barbara Basin, Californi...
متن کاملThe Development of the Polychaete
The eggs of Haploscoloplos fragilis, laid in gelatinous cocoons, develop as yolky trochophores which add 4 segments before hatching on the 6th day and two more during a pelagic phase before settling and the onset of feeding on the 10th day. The 6 (embryonic) segments bear a metatroch and 5 amphitrochs. The embryo also has an akrotroch, prototroch, telotroch, and neurotroch. All cilia disappear ...
متن کاملPrecision of readout at the hunchback gene
The simultaneous expression of the hunchback gene in the multiple nuclei of the developing fly embryo gives us a unique opportunity to study how transcription is regulated in functional organisms. A recently developed MS2-MCP technique for imaging transcription in living Drosophila embryos allows us to quantify the dynamics of the developmental transcription process. The initial measurement of ...
