Induction of anterior neural fates in the ascidian Ciona intestinalis
The sensory vesicle of ascidians is thought to be homologous to the vertebrate forebrain and midbrain (Development 125 (1998) 1113). Here we report the isolation of two sensory vesicle markers in the ascidian Ciona intestinalis, which are homologs of vertebrate otx and gsx homeobox genes. By using these markers to analyze the induction of anterior neural tissue in Ciona, we find that the restri...
متن کاملStudy of Cis-regulatory Elements in the Ascidian Ciona intestinalis
The ascidian (sea squirt) C. intestinalis has become an important model organism for the study of cis-regulation. This is largely due to the technology that has been developed for assessing cis-regulatory activity through the use of transient reporter transgenes introduced into fertilized eggs. This technique allows the rapid and inexpensive testing of endogenous or altered DNA for regulatory a...
متن کاملProteomic profiles of embryonic development in the ascidian Ciona intestinalis.
We report here proteomics-based protein profiles of three embryonic stages of the ascidian Ciona intestinalis. Two-dimensional gel electrophoresis revealed 416, 539, and 695 protein spots in the unfertilized eggs, 16 cell-stage embryos, and tadpole larvae, respectively. Comparative and quantitative analyses of the spot patterns identified proteins showing an increase or decrease in amount durin...
متن کاملCRISPR/Cas9-mediated gene knockout in the ascidian Ciona intestinalis
Knockout of genes with CRISPR/Cas9 is a newly emerged approach to investigate functions of genes in various organisms. We demonstrate that CRISPR/Cas9 can mutate endogenous genes of the ascidian Ciona intestinalis, a splendid model for elucidating molecular mechanisms for constructing the chordate body plan. Short guide RNA (sgRNA) and Cas9 mRNA, when they are expressed in Ciona embryos by mean...
متن کاملNovel endostyle-specific genes in the ascidian Ciona intestinalis.
The endostyle is a pharyngeal organ of Urochordata, Cephalochordata and larval Cyclostomata. This organ secretes mucus-proteins for internal filter feeding, a feeding system that must have developed in the common ancestor of these subphyla. Therefore, the endostyle is a key structure to understanding the origin and evolution of chordates. A previous study of the overall gene expression in Ciona...
