Figure 4From: The evolution of cardiolipin biosynthesis and maturation pathways and its implications for the evolution of eukaryotesAn evolutionary route chart of CL biosynthesis and maturation pathways in eukaryotes. Short black bar, CLS_cap gene; Short red bar, CLS_pld gene; Grey dot, CL maturation pathway genes; Hollow dot, absence of CL maturation pathway. EGT, endosymbiotic gene transfer from proto-mitochondrion to nucleus.Back to article page
