Consistent with the evolutionary divergence in regulation of Hh signaling between vertebrates and invertebrates, we found that Drosophila and C. elegans Gli homologues are not localized to the cilia when expressed in ciliated mouse fibroblasts.
To evaluate the contribution of indels and SVs in promoter regions to expression divergence and regulation, 24 genes with expression divergence/regulation between Nipponbare and Pokkali under either normal or high salinity stress conditions were selected.
Divergence of regulation of gene expression after gene amplification has also been reported in maize [ 15, 34].
In this article, we describe the A-to-I RNalternativend alternative splicing found in insect nAChR alpha6 genes, as well as their evolutionary conservation and divergence, and regulation.
Genomic variations in promoter regions resulted from single nucleotide polymorphisms, indels (1 10 bp of insertion/deletion), and structural variations significantly contributed to the expression divergence and regulation.
This divergence in regulation is probably related to the fact that glucose, a nutrient sensed by TORC1, triggers anaerobic fermentation in yeast.
sphaeroides affects 24%% of its genome, however, only 171 genes are differentially expressed in common between two Rhodobacter species, suggesting significant divergence in regulation.
Genomic variations in promoter regions resulted from SNPs, indels (1 10 bp of insertion/deletion), and structural variations (SVs, including large scale deletions, insertions, duplications, inversions, and translocations) significantly contributed to the expression divergence and regulation.
Our data also showed that tandem and segmental duplication, CACTA and hAT elements played roles in the evolution of gene expression divergence and regulation between these two contrasting genotypes under normal or high salinity stress conditions.
Further comparative genomics studies report that at least 20% of gene duplicates have been maintained in zebrafish, often by divergence of regulation between the duplicate loci that imposes an evolutionary constraint on both genes [ 22].
Our data also showed that tandem and segmental duplication, CACTA and hAT elements significantly contributed to expression divergence and regulation between these two contrasting genotypes under normal conditions or high salinity stress.
