Figure 4From: Multiple lineage specific expansions within the guanylyl cyclase gene familyPhylogenetic tree derived from partial cyclase domain. Bootstrap supports are shown for select nodes. Large number of polytomies are the result of the cyclase domain being relatively short and highly conserved. Echinoderm sequence data were taken from [73] and we have maintained their notation. A select number of sequences present in Figure [2] are also included in this phylogeny.Back to article page
