January 2012: Recent visiting scientist Rob Baker passed his PhD defense. As a graduate student in the Diggle Lab at the University of Colorado, he focused on the evolution of shoot architecture by examining the molecular developmental pathways within and among populations, where genetic divergence, adaptation, and speciation occur. |
|
January 2012: A paper on the age of Arabidopsis thaliana by Mark Beilstein, Sarah Mathews, and colleagues was highlighted at ScienceWatch.com as a “New Hot Paper” in the area of plant and animal science. This means that the paper, published in October 2010, was one of the most-cited papers in this area in the last two years. abstract » |
|
December 2011: Arboretum associate Rob Baker and Pam Diggle published new work in the American Journal of Botany examining the differences in shoot architecture between two populations of Mimulus guttatus. One population has a highly branched perennial lifestyle, while plants from the other population are less branched and annual. They found that shifts in the timing of reproduction play a role in the different patterns of branching. abstract » |

November 2011: The transportation of water through xylem cells can occasionally be blocked by air bubbles in a process called embolism. In new work published in Plant Physiology, Francesca Secchi and Maciej Zwieniecki shed light on the mechanisms involved in embolism repair by examining global transcription profiles in poplar trees (Populus trichocarpa). abstract » |
