Figure 3From: Complete mitochondrial DNA sequence of oyster Crassostrea hongkongensis-a case of "Tandem duplication-random loss" for genome rearrangement in Crassostrea?Pair analysis of mitochondrial genome rearrangements with SPRING (Sorting Permutation by Reversals and block-INterchanGes) in the three Crassostrea species. Star symbol denotes indel genes; dots, solid triangles and squares indicate block-interchange genes during putative genome rearrangements of Crassostrea, respectively. Symbols connected by line denote abutted genes. Double-arrows represent directions and steps in putative procedure of genome rearrangements.Back to article page
