Journal Article
Mita, K., Kawai, N., Rueckert, S., & Sasakura, Y. (2012)
Large-scale infection of the ascidian Ciona intestinalis by the gregarine Lankesteria ascidiae in an inland culture system. Diseases of Aquatic Organisms, 101(3), 185-195. https://doi.org/10.3354/dao02534
An important way to keep transgenic and mutant lines of the ascidian Ciona intestinalis, a model system for e.g. genetic functions, in laboratories is via culturing systems. H...
