Fig. 4From: Synteny analysis in Rosids with a walnut physical map reveals slow genome evolution in long-lived woody perennialsA dot plot of the 16 walnut physical maps on the vertical axis, with the starting nucleotide of each physical map at the top, and the 19 grape pseudomolecules on the horizontal axis, with the staring nucleotide on the left. Each dot represents a collinear gene pair identified by MCScanX between walnut and grape. Different colors of dots represent different collinear blocks of genesBack to article page
