A predictive model, based on the definition of an enthalpy function, is constructed for the evolutionary heat transfer behaviour of the butt-fusion welding process for polymer pipes.
A very impressive example of the contribution of nutrition to gut microbiota is the evolutionary recent transfer of genes for carbohydrate-active enzymes (porphyranases) from marine bacteria thriving on red algae of the genus Porphyra to commensal gut bacteria of the Japanese population.
These kinds of transfers are predominantly evolutionary one-way transfers, where parasites or symbionts are donors of genes to host cells.
The time of lineage coexistence, evolutionary distance between transfer partners, and quantity of transferred substitutions corresponded to appropriate edge lengths in the phylogenies of figure 1 (see Materials and Methods for details).
Nevertheless they may represent an important evolutionary possibility for transfer of genetic information between host cells, since the amino acid sequences gave very high BLASTP scores with Ostreococcus spp. proteins, and have thus not had time to degenerate extensively by mutations, deletions, or other rearrangements.
As for other evolutionary processes, the transfer of chloroplast-encoded genes to the nuclear genome is difficult, if not impossible, to observe.
In bacteria, "HGT" refers to both homologous recombination, which results in the exchange of orthologous genes between evolutionary lineages, and transfer of a gene from one evolutionary lineage to another.
In order to uncover the mechanistic details of plant-to-plant HGT, the extent and evolutionary fate of transfer was investigated between two groups: the parasitic genus Cuscuta and a small clade of Plantago species.
There are two alternative solutions to resolve this paraphyly: 1) synonymize Syncope with Chiasmocleis or 2) recognize Syncope as a separate evolutionary lineage and transfer some currently recognized species of Chiasmocleis to Syncope.
Literally, only endosymbiosis solves both problems, because cytoplasmic inheritance enables the evolutionary loss or transfer of genes and DNA to the nucleus, which in turn permits the evolution of intracellular trafficking systems at no net energetic cost, while leaving in place the core genomes necessary for respiration across a wide area of membranes.
