A major constraint on cpDNA is its organization into large clusters of polycistronically transcribed genes [ 5- 7].
Large networks, such as the telecommunications or transportation networks of a nation, often exhibit community structure, i.e., the organization of vertices into clusters with many edges joining vertices of the same cluster and comparatively few edges joining vertices of different clusters.
One of the most relevant characteristics of graphs representing real systems is the structure of communities, i.e., the organization of vertices into clusters, with many edges between the vertices of the same cluster and relatively few edges connecting vertices of different clusters.
After two days, only the blend electrospun nanofiber scaffolds facilitated epithelial cell self-organization into cell clusters, assessed with nuclear area and nearest neighbor distance measurements, leading to the apicobasal polarization of salivary gland epithelial cells after six days, which is vital for cell function.
Note that a finer organization of the collection into clusters and threads [36, 37] is possible, but the notion of threads seldom applies outside of the news domain while links generation on the base of a few keywords is domain independent.
Pump groups refers to the organization of individual pumps into clusters or groups.
Therefore, the organization of related mycobacteriophages into clusters provides a framework for identifying and interpreting gene trafficking within and among potentially distinct groups of genomes.
Further analyses indicated that the S. aureus tar genes, different from the divergon organization in B. subtilis, are organized into several clusters in cis.
In the genome sequence of Populus [ 35] we indeed can observe an organization of PR-10 genes into clusters.
We investigated the possible correlation between OR gene polymorphism and the organization of these OR genes into clusters of different sizes, by ranking the 109 OR genes according to SNP content.
