Evolution of sea urchin retroviral-like (SURL) elements: evidence from 40 echinoid species.

We conducted a phylogenetic survey of sea urchin retroviral-like (SURL) retrotransposable elements in 33 species of the class Echinoidea (sea urchins, sand dollars, and heart urchins). A 263-bp fragment from the coding region of the reverse transcriptase (RT) gene was amplified, cloned, and sequenced. Phylogenetic relationships of the elements isolated from independent clones, along with those ...

Phylogeny, rates of evolution, and patterns of codon usage among sea urchin retroviral-like elements, with implications for the recognition of horizontal transfer.

Phylogenetic relationships, rates of evolution, and codon usage were investigated in a family of retrotransposons (SURL elements) found in echinoids. The phylogeny of SURL element reverse transcriptase sequences from 10 echinoid species clearly shows the phylogenetic signature of the host taxa as well as paralogous sequences that diverged prior to speciation events. Two subfamilies (1 and 5) of...

Eutacticity in sea urchin evolution.

An eutactic star, in a n-dimensional space, is a set of N vectors which can be viewed as the projection of N orthogonal vectors in a N-dimensional space. By adequately associating a star of vectors to a particular sea urchin, we propose that a measure of the eutacticity of the star constitutes a measure of the regularity of the sea urchin. Then, we study changes of regularity (eutacticity) in a...

The evolution of sea urchin sperm bindin.

Sea urchins have been model organisms for the study of fertilization for more than a century. Fertilization in sea urchins happens externally, which facilitates the study of sperm-egg attachment and fusion, and means that all of the molecules involved in gamete recognition and fusion are associated with the gametes. Sea urchin sperm bindin was the first "gamete recognition protein" to be isolat...

Genetic divergence between three sea urchin species of the genus Strongylocentrotus from the Sea of Japan.

Intraspecific allozymic variation and interspecific genetic divergence were studied in three sea urchin species of the genus Strongylocentrotus (S. intermedius, S. nudus, S. pallidus) from the Sea of Japan. S. pallidus and S. intermedius showed high mean values of expected heterozygosity, H(e)=0.223+/-0.072 (17loci) and H(e)=0.230+/-0.065 (19loci), respectively. This estimate was somewhat lower...
