Tentacles test tenets of evolution
Elie Dolgin | Nov 17, 2008 | 3 min read
Novel genes, rather than regulatory DNA, underlie the evolution of morphological traits, according to research published today (Nov. 17) in __PLoS Biology__. The new linkurl:study;http://biology.plosjournals.org/perlserv/?request=get-document&doi=10.1371/journal.pbio.0060278 reports that genes found in simple freshwater animals -- but not in any other evolutionary lineage -- can drive changes in body plan, and stokes the flames of a long-standing debate among evolutionary developmental biologist
Rooting out plant stress responses
Elie Dolgin | Apr 23, 2008 | 2 min read
Plant cellular responses are much more locally and temporally specialized than previously thought, a new study suggests. In growing Arabidopsis roots, different tissue layers respond to stressful conditions in highly cell-type specific ways, according to linkurl:research;http://www.sciencemag.org/cgi/content/abstract/115379 published online today (April 24) in Science. "By and large, plants have been viewed as single, uniform entities," said linkurl:Philip Benfey;http://www.biology.duke.edu/b

By Karen Hopkin Master Plans Sean Carroll earned his celebrity by stitching together the patterning that underlies much of the animal kingdom’s various shades and shapes. © Eric Tadsen Sean Carroll’s most flamboyant finding was prompted by an innocent query before a seminar. Carroll had gone down to Duke University to give a talk about his research on the genes and molecules that direct the regular spacing of bri

Alternative Splicing Goes Mainstream
Sam Jaffe | Dec 14, 2003 | 10 min read
In eukaryotic genetics, the one-gene/one-protein concept has, for the most part, breathed its last. Researchers have rallied behind mechanisms such as alternative splicing, which may allow a lowly 30,000-gene genome to produce the dizzying variety of proteins that some believe is necessary to produce beings as complex as humans. Alternative splicing--the post-transcriptional editing process that can result in various mRNAs--was previously seen as an interesting but relatively uncommon sidesh
