...., 2019 ; Miyamoto and Crowther, 1985 ). The ascidian tunicate Ciona intestinalis type A ( Ciona robusta ) embryo also shows a curved body shape with its tail bending ventrally (ventroflexion) during the early- to mid-tailbud stages (stage 19 to stage 22, as defined by Hotta et al., 2007 ), after...

... attenuated Eed transcripts but did not affect the gene expression of pre-activated MRCs. A tunicate humoral factor, TC14-3, could induce Eed , accompanying the reactivation of MRC in adult zooids. When RNAi of Eed and Eed induction were performed simultaneously, zooidal cells and tissues failed to engage...

...Yoshimasa Sagane; Karin Zech; Jean-Marie Bouquet; Martina Schmid; Ugur Bal; Eric M. Thompson Extracellular matrices play important, but poorly investigated, roles in morphogenesis. Extracellular cellulose is central to regulation of pattern formation in plants, but among metazoans only tunicates...

...Jun Matsumoto; Chiaki Nakamoto; Shigeki Fujiwara; Toshitsugu Yubisui; Kazuo Kawamura We have isolated two Ca 2+ -dependent, galactose-binding polypeptides from the budding tunicate, Polyandrocarpa misakiensis . Based on their partial amino acid sequences, full-length cDNAs were cloned. One of them...

...Peter W. H. Holland; Jordi Garcia-Fernàndez; Nic A. Williams; Arend Sidow ABSTRACT All vertebrates possess anatomical features not seen in their closest living relatives, the protochordates (tunicates and amphioxus). Some of these features depend on develop mental processes or cellular behaviours...

...Kazuo Kawamura; Kenji Hara; Shigeki Fujiwara ABSTRACT We have extracted retinoids from the budding tunicate Polyandrocarpa misakiensis and, using HPLC, identified some major peaks as cis- retinal, all- trans- retinal and all- trans- retinoic acid, of which cis- retinal was most abundant (∼2 M...
