The amphioxus genome and the evolution of the chordate karyotype
Whole-genome comparisons illuminate the murky relationships among the three chordate groups (tunicates, lancelets and vertebrates), and allow not only reconstruction of the gene complement of the last common chordate ancestor but also partial reconstruction of its genomic organization.
The Draft Genome of Ciona intestinalis: Insights into Chordate and Vertebrate Origins
A draft of the protein-coding portion of the genome of the most studied ascidian, Ciona intestinalis, is generated, suggesting that ascidians contain the basic ancestral complement of genes involved in cell signaling and development.
Using the Acropora digitifera genome to understand coral responses to environmental change
Corals inhabit environments where they are frequently exposed to high levels of solar radiation, and analysis of the Acropora genome data indicates that the coral host can independently carry out de novo synthesis of mycosporine-like amino acids, which are potent ultraviolet-protective compounds.
Gene expression profiles of transcription factors and signaling molecules in the ascidian embryo: towards a comprehensive understanding of gene networks
The genomewide approach to networks of developmental genes in Ciona embryos is discussed and transcription factor genes and signal transduction genes involved in each of the downstream processes can be deduced comprehensively using the present approach.
Draft Assembly of the Symbiodinium minutum Nuclear Genome Reveals Dinoflagellate Gene Structure
Horizontal Gene Transfer from Diverse Bacteria to an Insect Genome Enables a Tripartite Nested Mealybug Symbiosis
Regulatory Blueprint for a Chordate Embryo
Deduced gene circuit diagrams describing the formation of larval tissues were computationally visualized and constitute a blueprint for the Ciona embryo and provide a foundation for understanding the evolutionary origins of the chordate body plan.

The genomic organization and spatiotemporal expression of all Hox as well as extended Hox member genes (Evx and Mox) of C. intestinalis are examined and it is suggested that the cluster organization and colinearity of the Hox genes are under dispersing and disintegrating conditions.
The ascidian Mesp gene specifies heart precursor cells
Cs-Mesp, the sole ortholog of vertebrate Mesp genes in the ascidian Ciona savignyi, is specifically and transiently expressed in the embryonic heart progenitor cells and is suggested to be essential for the specification of heart precursor cells.
