The rapid evolution of reproductive proteins
Many genes that mediate sexual reproduction, such as those involved in gamete recognition, diverge rapidly, often as a result of adaptive evolution. This widespread phenomenon might have importantExpand

Maximum-likelihood analysis of molecular adaptation in abalone sperm lysin reveals variable selective pressures among lineages and sites.
Maximum-likelihood models of codon substitution were used to analyze sperm lysin genes of 25 abalone (HALIOTIS:) species to identify lineages and amino acid sites under diversifying selection. TheExpand

The Genome of the Sea Urchin Strongylocentrotus purpuratus
We report the sequence and analysis of the 814-megabase genome of the sea urchin Strongylocentrotus purpuratus, a model for developmental and systems biology. The sequencing strategy combinedExpand

Evolution of gamete recognition proteins.
REVIEW Although fertilization has been studied for more than a century, the cell surface proteins mediating the process are only now becoming known. Gamete interaction in animals appears to beExpand

Rapid evolution of fertilization selectivity and lysin cDNA sequences in teguline gastropods.
Proteins mediating intercellular recognition face opposing selective forces as they evolve: purifying selection to maintain function, and diversifying selection to alter specificity. Lysin is aExpand

Chemotaxis of Arbacia punctulata spermatozoa to resact, a peptide from the egg jelly layer
Resact, a peptide of known sequence isolated from the jelly layer of Arbacia punctulata eggs, is a potent chemoattractant for A. punctulata spermatozoa. The chemotactic response is concentrationExpand

Nonsynonymous substitution in abalone sperm fertilization genes exceeds substitution in introns and mitochondrial DNA.
Strong positive Darwinian selection acts on two sperm fertilization proteins, lysin and 18-kDa protein, from abalone (Haliotis). To understand the phylogenetic context for this dramatic molecularExpand

Direct sequencing of genomic DNA for characterization of a satellite DNA in five species of eastern Pacific abalone.
A tandemly repeated satellite DNA of 290-291 base pairs (bp) was identified by SalI digestion of genomic DNA of five species of Eastern Pacific (California) abalone (genus, Haliotis). FollowingExpand
