Local Cues and Asymmetric Cell Divisions Underpin Body Plan Transitions in the Moss Physcomitrella patens
BACKGROUND Land plants evolved from aquatic algae more than 450 million years ago. Algal sisters of land plants grow through the activity of apical initial cells that cleave either in one plane to generate filaments or in two planes to generate mats. Acquisition of the capacity for cell cleavage in three planes facilitated the formation of upright bushy body plans and enabled the invasion of la...
متن کاملEmbryonic divisions
The British prime minister, Gordon Brown, may have been hoping for a quiet Easter break but he soon got warning in the press of an issue that would scupper any such thoughts. The government is backing a bill that will put into law many of the practices currently licensed case by case by the Human Fertilization and Embryology Authority.

At the lower end of this long tube is the large intestine, serving, it is usually taught, as a reservoir to receive, store, and periodically discharge the accumulation of waste. Throughout the small intestine the contents are...
متن کاملPer-Pixel Divisions
We describe a method to perform per pixel divisions using graph ics hardware with a simple iterative algorithm In the worst case the number of rendering passes is for approximate divisions and for accurate divisions The algorithm can be used for D vec tor normalization evaluating complex lighting models and image reconstruction Introduction and Previous Work Graphics hardware can act as a power...
متن کاملOn Noncommutative Involutive Divisions
Buchberger’s algorithm for computing a Gröbner basis solves the ideal membership problem over commutative polynomial rings. In the early 1990’s, an alternative to this algorithm was found, namely the involutive basis algorithm, which provides a Gröbner basis with extra combinatorial properties. Buchberger’s work was generalised to noncommutative polynomial rings by Bergman and Mora during the 1...
