Ciona intestinalis
- Differential temporal control of Foxa.a and Zic-r.b specifies brain versus notochord fate in the ascidian embryo
Summary: The temporally non-overlapping expression of Foxa.a and Zic-r.b in the brain lineage is regulated by three repressors: Prdm1-r.a, Prdm1-r.b and Hes.a.
- Antagonism between β-catenin and Gata.a sequentially segregates the germ layers of ascidian embryos
Summary: The antagonistic action between β-catenin and Gata.a in Ciona intestinalis is involved in segregation between ectoderm and endomesoderm at the 16-cell stage, and between endoderm and mesoderm at the 32-cell stage.
