Transcriptional diversification and functional conservation between DELLA proteins in Arabidopsis.

abstract：:The Orthonectida is a small, poorly known phylum of parasites of marine invertebrates. Their phylogenetic placement is obscure; they have been considered to be multicellular protozoans, primitive animals at a "mesozoan" grade of organization, or secondarily simplified flatworm-like organisms. The best known species in...

In contrast to standard representation of the distribution of evolutionary rates, this model allows the site-specific rate to vary between lineages. This is achieved by adding as few as two parameters to the widely used among-site rate vari...
