In addition, broadly expressed protein-coding genes are more conserved than those with a narrow expression profile [ 31].
As our knowledge of cellular proteins manipulated by HIV-1 expands, we expect that more proteins will be discovered that exhibit similar characteristics to Mov10 these being a narrow expression window in which HIV-1 is capable of reproducing.
This poses no problem at the low expression end, but at the high expressions the density of genes within a narrow expression interval is small and a certain number of genes (probe sets) must be excluded.
The combination of the effect of the transgene with the range of selection generated by the antibiotic resistance marker can produce a narrow expression range that can mimic the physiological function range of expression.
Of eudicot MADS box genes, C and B function genes generally show a narrow expression pattern, which directly reflects their function in carpel, stamen, and petal development, respectively [ 27, 53, 54].
For D. melanogaster and Mus musculus, it has been shown that sex-biased genes showing tissue-specific gene expression in reproductive tissues, and thus having a narrow expression profile within the organism, show faster rates of evolution than unbiased genes with tissue-specific expression or those with broader expression profiles (Meisel 2011).
This makes it clear that each cell does not occupy a narrow expression bin, with the overall population distribution arising from a sum of cell behaviors constrained to these small bins, but rather that each cell moves over time through the entire range of expression seen in the population, occupying a different position in this distribution at any moment.
In contrast to other GSQUA genes, GSQUA1 was entirely restricted to the vasculature of the capitulum receptacle and petals [ 4].While GSQUA2 and GSQUA5 were found to be expressed in all parts of the inflorescence, GSQUA3 and GSQUA6 displayed a slightly narrower expression pattern at the inflorescence level.
On either side of the podium were vertical banners with images of Moin — a gray-haired man with a narrow face and an expression of kindly intelligence.
Narrower expression breadths were associated with a larger percentage of recent SSD genes (KS < 1.0, red), whereas the percentage of ancient SSD genes (KS ≥ 1.0, pink) was nearly constant regardless of expression breadth.
