...Yosuke Ogura; Asako Sakaue-Sawano; Masashi Nakagawa; Nori Satoh; Atsushi Miyawaki; Yasunori Sasakura Chordates undergo a characteristic morphogenetic process during neurulation to form a dorsal hollow neural tube. Neurulation begins with the formation of the neural plate and ends when the left...

...Brad Davidson; Weiyang Shi; Michael Levine The bHLH transcription factor Mesp has an essential but ambiguous role in early chordate heart development. Here, we employ the genetic and morphological simplicity of the basal chordate Ciona intestinalis to elucidate Mesp regulation and function...

...Tokiharu Takahashi; Peter W. H. Holland The ancestral chordate neural tube had a tripartite structure, comprising anterior, midbrain-hindbrain boundary (MHB) and posterior regions. The most anterior region encompasses both forebrain and midbrain in vertebrates. It is not clear when or how...

... in mice, the present results suggest that a mechanism for heart specification beginning with Mesp through Nkx and HAND is conserved among chordates. † Author for correspondence (e-mail: [email protected] ). * These authors contributed equally to this work 17 2 2004...

... duplication Chordate Vertebrate Evolution Much of the progress made in our understanding of developmental processes over recent years has been the result of the identification of genes responsible for mutant phenotypes in the Drosophila embryo. The subsequent cloning of vertebrate homologues...

...Hefzibah Eyal-Giladi ABSTRACT A master plan for the early development of all chordates is proposed. The radial symmetry of the chordate ovum is changed at or after fertilization into a bilateral symmetry by an external signal. Until now two alternative triggers, sperm entry and gravity, have been...
