Fig. 3From: Massive expansion of P-selectin genes in two Venerida species, Sinonovacula constricta and Mercenaria mercenaria: evidence from comparative genomics of BivalviaThe phylogenetic tree of P-selectin genes. M. philippinarum, B. platifrons, S. constricta, M. mercenaria, P. maximus, P. fucata, C. gigas and C. virginica genes are distinguished by different colors. Subfamilies I, II, III, and IV are highlighted in purple, dark blue, dark green and light green, respectively. Branches marked with yellow represent type-A P-selectins and dark blue branches represent type-B P-selectinsBack to article page
