A bountiful harvest: genomic insights into crop domestication phenotypes.
Human selection during crop domestication has resulted in remarkable transformations of plant phenotypes, providing a window into the genetic basis of morphological evolution. Recent progress in our understanding of the genetic architecture of novel plant traits has emerged from combining advanced molecular technologies with improved experimental designs, including nested association mapping, g...
متن کاملComparative genomics of grasses promises a bountiful harvest.
Building on a rich history of comparative genomics, scientists are making rapid progress toward a comprehensive framework for comparative genomics of the grass family (Poaceae) that will permit comparative studies at new levels of intricacy. The sequences of each of the two rice (Oryza sativa) subspecies (Goff et al., 2002; Yu et al., 2002, 2005b; Matsumoto et al., 2005), the recent completion ...
متن کاملCryovolcanism on Ceres.
Volcanic edifices are abundant on rocky bodies of the inner solar system. In the cold outer solar system, volcanism can occur on solid bodies with a water-ice shell, but derived cryovolcanic constructs have proved elusive. We report the discovery, using Dawn Framing Camera images, of a landform on dwarf planet Ceres that we argue represents a viscous cryovolcanic dome. Parent material of the cr...

متن کاملThe missing large impact craters on Ceres
Asteroids provide fundamental clues to the formation and evolution of planetesimals. Collisional models based on the depletion of the primordial main belt of asteroids predict 10-15 craters >400 km should have formed on Ceres, the largest object between Mars and Jupiter, over the last 4.55 Gyr. Likewise, an extrapolation from the asteroid Vesta would require at least 6-7 such basins. However, C...
