Evidence that male sea lamprey increase pheromone release after perceiving a competitor: raw data, R-code, R analyses
<p class="CxSpFirst">Sexual signals evolve via selective pressures arising from male-male competition and female choice, including those originating from unintended receivers that detect the signal. For example, males can acquire information from other males signaling to females and alter their own signal. Relative to visual and acoustic signals, less is known about how such communication networks influence chemical signaling among animals. In sea lamprey (<i>Petromyzon marinus</i>), chemical communication system is essential for reproduction, offering a useful system to study a pheromone communication network that includes signalers and both intended and unintended receivers. Male sea lamprey aggregate on spawning grounds where individuals build nests and signal to females using sex pheromones. We examined how exposure to a major component of the male pheromone, 3keto-petromyzonol sulfate (3kPZS), influenced male pheromone signaling, and whether females had a preference for males that altered their signal. Exposure to 3kPZS, at a concentration of 5x10<sup>-10 </sup>M, simulated the presence of other male(s) and led to increased 3kPZS release rates within 10 min, followed by a return to baseline levels within 30 min. Exposure also led to increases in hepatic synthesis and circulatory transport of pheromone components. In behavioral assays, females preferred the odor of males that had been exposed to 3kPZS; therefore, males likely benefit from upregulating 3kPZS release after detecting competition for mates. Here, we define how a specific pheromone component influences chemical signaling during intrasexual competition, and show a rare example of how changes in chemical signaling strategies resulting from male competition may influence mate choice.</p>

Data from: Genome-wide analysis of the ATP-binding cassette (ABC) transporter gene family in sea lamprey and Japanese lamprey
Background: Lampreys are extant representatives of the jawless vertebrate lineage that diverged from jawed vertebrates around 500 million years ago. Lamprey genomes contain information crucial for understanding the evolution of gene families in vertebrates. The ATP-binding cassette (ABC) gene family is found from prokaryotes to eukaryotes. The recent availability of two lamprey draft genomes from sea lamprey Petromyzon marinus and Japanese lamprey Lethenteron japonicum presents an opportunity to infer early evolutionary events of ABC genes in vertebrates. Results: We conducted a genome-wide survey of the ABC gene family in two lamprey draft genomes. A total of 37 ABC transporters were identified and classified into seven subfamilies; namely seven ABCA genes, 10 ABCB genes, 10 ABCC genes, three ABCD genes, one ABCE gene, three ABCF genes, and three ABCG genes. The ABCA subfamily has expanded from three genes in sea squirts, seven and nine in lampreys and zebrafish, to 13 and 16 in human and mouse. Conversely, the multiple copies of ABCB1-, ABCG1-, and ABCG2-like genes found in sea squirts have contracted in the other species examined. ABCB2 and ABCB3 seem to be new additions in gnathostomes (not in sea squirts or lampreys), which coincides with the emergence of the gnathostome-specific adaptive immune system. All the genes in the ABCD, ABCE and ABCF subfamilies were conserved and had undergone limited duplication and loss events. In the sea lamprey transcriptomes, the ABCE and ABCF gene subfamilies were ubiquitously and highly expressed in all tissues while the members in other gene subfamilies were differentially expressed. Conclusions: Thirteen more lamprey ABC transporter genes were identified in this study compared with a previous study. By concatenating the same gene sequences from the two lampreys, more full length sequences were obtained, which significantly improved both the assignment of gene names and the phylogenetic trees compared with a previous analysis using partial sequences. The ABC gene subfamilies in chordates have undergone obvious expansion or contraction. The ABCA subfamily showed the highest gene expansion rate during chordate evolution. The evolution of ABC transporters in lampreys requires further evaluation because the present results are based on a draft genome.
