Sentence examples for patchwork of genes from inspiring English sources

These results argue that the electron transport pathway is encoded by a patchwork of genes, some inherited vertically and others acquired from diverse phylogenetic sources.

With HGT, organismal evolution becomes a patchwork of genes from varied sources.

If, on the other hand, such a coherent pattern does not exist, this also would be notable indicating that, like many other systems, this key pathway is a patchwork of genes of different origins.

Defining GIs on CHR2 is not straightforward since its structure is very different from that of CHR1 and it appears to consist of a complicated patchwork of gene clusters and subclusters generated by multiple integration events with the subsequent retention (and occasional loss) of acquired genes.

Only few other genes or operons of the PZ are also present in P. luminescens, namely a chitinase, two iron acquisition systems, and three ysa genes, thus confirming the idea of a patchwork of horizontally acquired genes within the PZ [ 23].

In case of the LEE this may be the result of a recurrent loss and acquisition of genes (patchwork model), or of a loss of parts of the locus by deletion events subsequent to its primary acquisition as an entity [49].

On the other hand, the "patchwork hypothesis" [ 6] proposes that duplication of genes encoding promiscuous enzymes (capable of catalyzing multiple reactions) allows each descendant enzyme to specialize in one of the ancestral reactions.

Wolf et al. [ 4] concluded that the concept of a tree could only be rescued by weakening its meaning, and considering it only as "a central trend in the rich patchwork of evolutionary history, replete with gene loss and horizontal transfer events".

Both the retrograde and patchwork theories attempt to explain the evolution of metabolic networks based on gene and operon duplication linking distribution of genes on the chromosome which may be affected by rearrangements and consequently on the structure of the metabolic network [ 12].

The 'patchwork' shuffling of KIR sequences by recombination appears to allow distribution of the structural or regulatory attributes of existing KIR in the creation of new genes, as well as being involved in relegation of genes to pseudogenes and vice versa.

The consequence of such a patchwork of splice variants is that most mutations in the PCNT gene will not have global but tissue and even cell specific effects.
