We considered the following seven functional variables that are known to be important determinants of yeast evolutionary rates: gene expression, CAI, gene dispensability, degree, centrality, mRNA half-life, and fRNA coverage [9], [11].
Just like other PLoS content, it will be possible to make utilization of individual articles interactive for the users (human or machine) to harness elements of research (annotation tables, phylogenetic trees, evolutionary hierarchies, gene expression data, graphs, texts etc).
These expressed sequence tags (ESTs) may then be identified by homology to Mus and Rattus, thus providing data useful for evolutionary analysis, gene expression, and mapping.
SSRs have been demonstrated as important motifs involved within various biological events including evolutionary processes, gene expression, genetic disease, chromatin organization, and DNA metabolic processes [ 2– 4].
Taken together, our evolutionary and gene expression analyses demonstrate that our new TFBS predictions significantly improve on the previous annotations and that for a subset of genes, changes in predicted TFBSs correlate significantly with changes in gene expression divergence.
Second, by including information about gene duplication, our method aims to identify regions that are able to take on new functions by two complementary evolutionary mechanisms: gene expression divergence and protein sequence divergence.
Weaker transcription factor binding not only occurs abundantly in vivo but may also be functionally important features of the genomic regulatory program as revealed by evolutionary and gene expression analyses [ 43].
We propose that the evolutionary conserved gene expression between distinct lineages underpins the importance of SCD activity in the brain (and probably the pancreas), in a yet to be defined role.
Coding regions that are broadly expressed face many, sometimes contradictory, evolutionary constraints on gene expression evolution [ 40], and it may be that genes with extensive expression throughout an organism are less able to evolve sex-biased expression patterns without disrupting critical functions in other tissues.
Fragile genes have high evolutionary rates of genes expressionWe next asked whether fragile transcriptional regulatory program is linked to high evolutionary rate of gene expression.
