Phylogenomics and systematics of botryllid ascidians, and implications for the evolution of allorecognition

Allorecognition, the ability of an organism to distinguish kin from non-kin, or self from non-self, has been studied extensively in a group of invertebrate chordates, the colonial ascidians called botryllids (Subphylum Tunicata, Class Ascidiacea, Family Styelidae).  When two conspecific botryllid colonies come in contact, there are two potential outcomes to an allorecognition reaction: fusion or rejection. The rejection outcome of allorecognition varies by species and has been classified by type (referred to as R-type). R-type is defined according to how far the fusion process progresses before the rejection begins, since the rejection reaction appears as an interference of the fusion process. Here, we map evolution of R-types onto an extended and robust phylogeny of the botryllids. In this study, we have reconstructed the largest phylogenomic tree of botryllids, including 98 samples and more than 40 different species, and mapped on it nine of the 12 species for which the R-ty..., , , # Data from: Phylogenomics and systematics of botryllid ascidians, and implications for the evolution of allorecognition
