Covarion structure in plastid genome evolution: a new statistical test.
Covarion models of molecular evolution allow the rate of evolution of a site to vary through time. There are few simple and effective tests for covarion evolution, and consequently, little is known about the presence of covarion processes in molecular evolution. We describe two new tests for covarion evolution and demonstrate with simulations that they perform well under a wide range of conditi...
متن کاملGenome Evolution of a Tertiary Dinoflagellate Plastid
The dinoflagellates have repeatedly replaced their ancestral peridinin-plastid by plastids derived from a variety of algal lineages ranging from green algae to diatoms. Here, we have characterized the genome of a dinoflagellate plastid of tertiary origin in order to understand the evolutionary processes that have shaped the organelle since it was acquired as a symbiont cell. To address this, th...
متن کاملTesting the covarion hypothesis of molecular evolution.
The covarion hypothesis of molecular evolution states that the fixation of mutations may alter the probability that any given position will fix the next change. Tests of this hypothesis using the divergence of real sequences are compromised because models of rate variation among sites (e.g., the gamma version of the one-parameter equation) predict sequence divergence values similar to those for...
متن کاملMinimal plastid genome evolution in the Paulinella endosymbiont
first individual to scan was the first to cross the small road in 100% of cases, compared to 70% for the large road. On the large road the second-ranking male sometimes continued scanning while the elderly third male and alpha female took up the lead on the large-road progressions. The alpha male increased his rearward presence on the large road, whereas the alpha female showed a dramatic reduc...
متن کاملUpdate on Plastid Evolution Plastid Origin and Evolution: New Models Provide Insights into Old Problems
Algae are defined by their photosynthetic organelles (plastids) that have had multiple independent origins in different phyla. These instances of organelle transfer significantly complicate inference of the tree of life for eukaryotes because the intracellular gene transfer (endosymbiotic gene transfer [EGT]) associated with each round of endosymbiosis generates highly chimeric algal nuclear ge...
