Blood cells of _Ascidia gemmata_ contained ~350 mM ov vanadium. Other Phlebobranchia contained 20–60 mM, but _C. intestinalis_ contained only 0.6. Stolidobranchia contained much lower amounts. Vanadium-containing cells (vanadocytes) were identified as signet cells. Sulfonic acid might be the counter ion. Vanadocyte pH is very low (1.9–4.2). There exist other low-pH cells that do not contain vanadium. Accumulation of vanadium may involve a mechanism using a vacuolar-type H+-ATPase. Vanadium contents of the embryo are low but increase during embryogenesis."]] diff --git a/tags/Ciona.mdwn b/tags/Ciona.mdwn index 2ac8eea9..9ac123bc 100644 --- a/tags/Ciona.mdwn +++ b/tags/Ciona.mdwn @@ -97,4 +97,9 @@ with respcet to _C. roulei_ ([[Nydam and Harrison, 2010|biblio/20403444]]). - Mitochondrial gene order differs even within the _Ciona_ genus ([[Gissi, Iannelli and Pesole 2004|biblio/15114417]]). +## Other + +Blood cells of _C intestinalis_ (_robusta_?) contain vanadium ([[Michibata, +1996|biblio/10.2108_zsj.13.489]]). + [[!inline pages="tagged(Ciona)" actions="no" limit=0]]
