Two-Round Ca²⁺ transient in papillae by mechanical stimulation induces metamorphosis in the ascidian Ciona intestinalis type A.

ABSTRACT: Marine invertebrate larvae are known to begin metamorphosis in response to environmentally derived cues. However, little is known about the relationships between the perception of such cues and internal signalling for metamorphosis. To elucidate the mechanism underlying the initiation of metamorphosis in the ascidian, Ciona intestinalis type A (Ciona robusta), we artificially induced ascidian metamorphosis and investigated Ca²⁺ dynamics from pre- to post-metamorphosis. Ca²⁺ transients were observed and consisted of two temporally distinct phases with different durations before tail regression which is the early event of metamorphosis. In the first phase, Phase I, the Ca²⁺ transient in the papillae (adhesive organ of the anterior trunk) was cou
