Figure 1From: Adaptive evolution of the matrix extracellular phosphoglycoprotein in mammalsSIBLING (DSPP, DMP1, IBSP MEPE and SPP1) presence in vertebrates. Illustrative representation of the SIBLING (DSPP, DMP1, IBSP MEPE and SPP1) genes presence/absence in vertebrates. The estimated divergence time of the different groups are placed near the nodes.Back to article page
