Allogeneic Distinction in Botryllus primigenus and in other Colonial Ascidians

Abstract

Certain species of colonial ascidians have colony specificity or the ability to distinguish self colonies from not-self colonies within the same species. In Botryllus primigenus, when a colony recognizes another as belonging to the self strain, both colonies fuse with each other to form one colony (designated as “fusion”). On the contrary, when colonies of a not-self strain come into contact, they do not fuse, and a necrotic zone occurs at the contact surface between the two colonies (designated as “nonfusion”).
