Sentence examples for evolution of endogenous from inspiring English sources

Additionally, the Siluro-Devonian colonization of the land by plants was possible in part because the new shielding properties of the ozone layer arose concurrently with the evolution of endogenous color pigments to protect plants from UV light not filtered by the upper atmosphere (Duff and Nickrent 1998; Shear 2000; Rozema et al. 2002).

In conclusion, this study raises important issues surrounding the use of MRI and MRI contrast agents for longitudinal cell tracking studies in models of injury, where the evolution of endogenous contrast over time within lesioned tissue can be a source of uncertainty in image interpretation.

Given the large number of differences in enhancer activity detected in this study, our results suggest that changes in trans environments may be more common in vertebrate evolution than previously anticipated, and that some of these changes may be associated with evolution of endogenous gene expression.

Fig. 2 Influence of ethephon on the evolution of the endogenous enzyme activities contents, the polygalacturonases (PG) and the pectinesterases activities (PE) during the olives ripening.

In the numerical experiments that we perform, our model determines the evolution of the endogenous variables, given the initial capital stock in 1970 as measured in the data.

LTR-LTR recombination is an important source of genomic variation and evolution, as ∼85% of endogenous retroviruses are found as solo-LTRs in the human genome [6] and solo-LTR formation has been proposed to be a mechanism contributing to mitigating the increase in genome size caused by new transposable element insertions in plants [7].

In this case, however, this would not imply that these putative trans-changes have played a role in the evolution of the associated endogenous gene expression patterns in the two species.

B1) as the feline W locus. Segregation and sequence analysis of the KIT gene in two pedigrees (P1 and P2) revealed the remarkable retrotransposition and evolution of a feline endogenous retrovirus (FERV1) as responsible for two distinct phenotypes of the W locus, Dominant White, and white spotting.

Such LTR-based "sampling dating" is justified since the differences in the rates of evolution of exogenous retroviruses are six orders of magnitude higher than those of their endogenous ("frozen") counterparts.

Fig. 2 Influence of ABA on the evolution of the contents of endogenous enzyme activities, polygalacturonase (PG) and pectinestérases activities (PE) during the ripening of olives.

Here, we have aimed to directly test the potential impact of trans-changes in the evolution of enhancer activity and of endogenous gene expression.
