  1. Diversification of Hox Gene Clusters in Osteoglossomorph Fish in Comparison to Other Teleosts and the Spotted Gar Outgroup

    Kyle J Martin and Peter W H Holland

    Genomic sequencing of three osteoglossomorph fish reveals diversity in their Hox gene complements and radical differences to the previously studied Pantodon, indicating numerous independent gene losses and gene cluster losses after genome duplication. Variability is also seen in other teleost fish and contrasts with the slow-evolving genome of the spotted gar.

  2. Melanotransferrin: New Homolog Genes and Their Differential Expression during Intestinal Regeneration in the Sea Cucumber Holothuria glaberrima

    Four melanotranferrin genes are present in the sea cucumber Holothuria glaberrima. The higher levels of expression of these genes occur during intestinal regeneration, suggesting that the gene functions are associated with regenerative processes. Figure represents the sequence model of Hg MTf1, showing target region 26-756. The model was created at ModBase: Database of Comparative Structure Models.

  3. Comparison of Egg Envelope Thickness in Teleosts and its Relationship to the Sites of ZP Protein Synthesis

    We hypothesized that acquisition of liver-synthesized ZP proteins during teleost evolution conferred the ability to develop a thick egg envelope, which allowed species with demersal eggs to adapt to mechanical stress in the prehatching environment.

    An Evo-Devo Perspective on Multicellular Development of Myxobacteria (pages 165–178)

    Juan A. Arias Del Angel, Ana E. Escalante, León Patricio Martínez-Castilla and Mariana Benítez

    An Evo-Devo perspective considering interactions among genetic, environmental, and physicochemical processes may enhance studies on multicellularity. Developmental system drift and co-option help understand myxobacteria multicellularity.

  5. A Novel Dynamic Expression of vasa in Male Germ Cells during Spermatogenesis in the Chinese Soft-Shell Turtle (Pelidiscus sinensis)

    Wei Li, Piaoyi Zhang, Xuling Wu, Xinping Zhu and Hongyan Xu

    Version of Record online: 13 FEB 2017 | DOI: 10.1002/jez.b.22728

    Both Psvasa mRNA and protein are exclusively and dynamically expressed in the germ cells during spermatogenesis. Turtle vasa RNA is differentially expressed in the proliferating and resting spermatogonia. Turtle Vasa protein expression pattern in male germ cells is similar to that of mouse Vasa, but distinct from those of chick Vasa and fish Vasa.
