We report that 18 conserved, and by extension functional, elements in the human genome are the result of retroposon insertions that are evolving under purifying selection in mammals. We show evidence that 1 of the 18 elements regulates the expression of ASXL3 during development by encoding an alternatively spliced exon that causes nonsense-mediated decay of the transcript. The retroposon that g...

Plants use phytochrome photoreceptors to determine their proximity to other plants, to gauge the intensity of vegetational shade, and to determine whether they are near the surface of bare soil or buried under leaf litter. In each case, phytochromes are measuring the ratio of red (R) to far-red (FR) light in the environment, and plants are using the information to elicit critical developmental ...

Indeed, participants in a 2007 workshop sponsored by the National Academy of Sciences, entitled ‘Genetically Engineered Organisms, Wildlife, and Habitat’, agreed on the importance of proper comparisons. Referring to the findings of meeting participant LaReesa Wolfenbarger from University of Nebraska, a summary of the workshop said, “The conclusion Wolfenbarger...
