(12) By comparing the DNA sequences of the human and fish visual pigment genes and knowing their phylogenetic relationship, one can infer the direction of amino acid substitutions in the red and green visual pigments.
(13) If other techniques of phylogenetic analysis confirm this evolutionary tree, we propose that the photocytes be given urkingdom status.
(14) During phylogenetic evolution such changes only occur very slowly.
(15) Specificity studies suggest that the stingray insulin receptor may represent a phylogenetic position prior to the evolutionary divergence of insulin and the insulin-like growth factors.
(16) A phylogenetic tree constructed from the sequences of these bacteria and published sequences indicated that the coryneform bacteria consist of a distinct eubacterial branch together with Streptomyces and Micrococcus spp.
(17) The phylogenetical relationships of these aggregates with mammalian bone marrow are discussed.
(18) A phylogenetic tree based on allelic variation detected electrophoretically at 20 enzyme-encoding loci revealed two major clusters and several deep branches composed of strains that synthesize msDNA.
(19) Sequence divergence in the 16S rRNA obtained from alignment with published insect sequences is consistent with phylogenetic hypotheses, in that Diptera and Lepidoptera are more closely related to each other (24% sequence divergence) than either is to Hymenoptera (31%).
(20) A differential, temporal and spatial expression of this epitope in metamorphosing nervous tissue was outlined, that apparently characterises homologous neuronal populations in two phylogenetically distinct holometabolous insects, i.e.
Taxonomic
Definition:
(a.) Pertaining to, or involving, taxonomy, or the laws and principles of classification; classificatory.
Example Sentences:
(1) The taxonomic relationship of strains H4-14 and 25a with previously described Xanthobacter strains was studied by numerical classification.
(2) Bordetella pertussis and Bacillus anthracis, two taxonomically distinct bacteria, secrete adenylate cyclase toxins that are activated by the eukaryotic protein calmodulin.
(3) The present classification of vasculitis has several objections, based on the following aspects: 1) It does not take into account taxonomic rules; 2) It uses criteria which helps to cover up; 3) It uses generic terms without a specific meaning; 4) Lack of clinical interest.
(4) As an extension to the variety of existing techniques using polymorphic DNA markers, the Random Amplified Polymorphic DNA (RAPD) technique may be used in molecular ecology to determine taxonomic identity, assess kinship relationships, analyse mixed genome samples, and create specific probes.
(5) Authors pointed on etiologic connections between particular clinical syndroms in AIDS and microbial, parasitic and viral agents belonging to different taxonomic groups.
(6) Disclosure of the 5'-terminal sequence of the HCV genome would facilitate its taxonomic classification, and contribute toward immunological diagnosis of infection and development of vaccines.
(7) The threat or risk of the child involves a substantial taxonomic variety, therefore the author tries to define the entire area by terms such as risk factor, individual at risk, group at risk and risk situation, to assess their content and extent and their mutual relations.
(8) The results suggested that allergenic cross-reactivity between some fly species exists, and may extend to taxonomically unrelated insect species.
(9) The advantages of long-term preservation of suspensions of mycobacteria by storage at -70 degrees C established in earlier studies are reinforced by present evidence that freezer storage does not alter key taxonomic features used to identify mycobacteria.
(10) Fourteen Streptomyces strains from various numerical taxonomic classes and representatives of three other genera of actinomycetes were studied using an indirect enzyme-linked immunosorbent assay (IND-ELISA) to determine their serological relationships.
