High impact information on Genes, Insect

Evolutionary comparisons between these P450 genes are the first available for a group of insect genes transcriptionally regulated by hostplant allelochemicals and provide insights into the process by which insects evolve specialized feeding habits [1].
Therefore, this gene appears to have diverged from an ancestral gene common to both the engrailed and invected insect genes [2].
The upstream region of the p14 gene shares sequences present in insect genes known to be regulated in a sex-, temporal-, and tissue-specific manner by members of the steroid receptor superfamily [3].
This 19 exon insect gene, dMRP (FBgn0032456), spans slightly more than 22 kb [4].
Juvenile hormone regulation of an insect gene: a specific transcription factor and a DNA response element [5].

Biological context of Genes, Insect

Upstream of both insect genes, a conserved 19 bp inverted repeat sequence was detected [6].

Gene context of Genes, Insect

An Arabidopsis gene homologous to mammalian and insect genes encoding the largest proteasome subunit [7].
The rate of synonymous substitution in insect genes may be slower than that of vertebrates, but the nonsynonymous substitution rate, and hence the rate of TPI evolution, appears to be faster in insects than in vertebrates [8].
