Sentence examples for facultative nature from inspiring English sources

Currently, coral reef biologists have a limited capacity to satisfactorily explain the facultative nature of the symbiotic interaction between Symbiodinium and heterotrophic hosts [ 13].

(Here, we use the term 'progenitor zone' rather than the earlier term 'mitotic zone' or 'proliferative zone' to reflect the facultative nature of germ cell divisions).

Such facultative nature of oligotrophy, as shown by the K. pneumoniae MB45, may contribute to the reported adaptation of remaining viable in hospital environment [ 28] for several days and cause nosocomial infection.

Salmonella are particularly of interest due to their facultative anaerobic nature, facilitating colonization of differentially oxygenated tumor regions.

The low circulating cytokine response during systemic S. typhimurium infection may be attributed to the facultative intracellular nature of the organism.

More recently derived associations are typically facultative in nature; in these cases bacterial symbionts often provide ancillary benefits such as protection from natural enemies or enhanced tolerance towards conditional environmental stresses [18].

This scenario best explains why R. felis LSU-Lb lacks nearly all SNPs unique to other L. bostrychophila-associated R. felis strains, yet possesses the same host symbiont relationship as these strains relative to the facultative parasitic nature of the flea-associated strains.

Given the repetitive nature of this genome, as is the case for many other facultative or "recently" acquired intracellular endosymbionts, many of the gaps were flanked by repetitive regions or had them near the gaps, and manual prediction of primers avoiding repetitive sequence was time consuming.

Their biology varies from loosely associated facultative symbionts (often called Secondary (S) symbionts) to obligatory mutualists of a highly derived nature, called Primary (P) symbionts [ 7- 9].
