Fig. 1From: Both Conifer II and Gnetales are characterized by a high frequency of ancient mitochondrial gene transfer to the nuclear genomePatterns of loss and transfer of mitochondrial protein-coding genes in gymnosperms with sequencing depth and relative amount of gene copies of these genes. LEAFY was used as a reference (c) for mitochondrial and transferred genes in gymnosperms. Black color (b) indicates gene loss. Purple and black indicate mitochondrial and transferred genes, respectivelyBack to article page
