Gene order information is stored as a string of gene names separated by commas, with a minus sign indicating a gene on the minus strand. For each species the gene string is stored with and without tRNA genes. Hence for Didelphis virginiana we have

COX1,-S,D,COX2,K,ATP8,ATP6,COX3,G,ND3,R,ND4L,ND4,H,S2,L,ND5,-ND6,-E,CYTB, T,-P,F,RNS,V,RNL,L2,ND1,I,-Q,M,ND2,-A,-C,W,-N,-Y

and

COX1,COX2,ATP8,ATP6,COX3,ND3,ND4L,ND4,ND5,-ND6,CYTB,RNS,RNL,ND1,ND2

Entering a species name in the box below starts a search for species with the same gene order. Searching with Didelphis virginiana gives a list of 9 species (all of which are Marsupials). If the tRNAs are excluded, the search gives a much longer list of vertebrates.




Check the box to exclude tRNAs from the gene orders.

The following button creates a list of distinct gene orders, with one representative species for each gene order. To check which other species have this gene order, use the method above. Species names are abbreviated using the first three letters of the genus and species - i.e. HETMACMIT means Heterodoxus macropus mitochondrion.

Gene order information is sensitive to errors in annotation in the original files. (Not our fault!) We have corrected a large number of errors, as listed HERE.
