Figure 9 From: Specific retention of the protostome-specific PsGEF may parallel with the evolution of mushroom bodies in insect and lophotrochozoan brains The phylogeny of animals described in the text. The presence and absence of mushroom body-like structures are indicated with Y and N in red, respectively. The presence and absence of PsGEF with C2, PDZ, and RhoGEF domains are shown with Y and N in blue, respectively. The status is not known in annelids and platyhelminthes, and thus indicated with ?. Representative animal species are also shown in parentheses. Not all animal phyla are indicated.Back to article page
