Variation type	Difference in strain B REL606	Difference in strain K-12 DH10B	Evidence	Notes	Link leading to GEvo
1. Deletion	none	Deletion of ~18 genes including DNA pol II, genes in metabolic pathway, thiamine ABC transporter	pseudogenes in DH10B at deletion site.	Possible additional insertion in DH10B as evidenced by pseudogenes of yabP, RNA pol associated helicase and FruR, that are not present in REl606	tinyurl.com/yexrzpb
2. Insertion	Insertion of IS1 sequence and a "predicted" transposase	Insertion sequences and Prophage CP46 DNA insertion	Prophage specific genes found	Prophage DNA insertion created pseudogenes in K-12 DH10B	tinyurl.com/yd2quy7
3. Deletion in B strain or Insertion in K12 strain	Insertion of IS1 sequence. Insertion of ~15 genes including lac operon and other metabolic enzymes genes	Insertion of IS3 and IS2 sequence	Pseudogene made in DH10B by IS sequence and transposon insertion	Possible insertion in B REL606 as evidenced by direct repeats.	http://tinyurl.com/yedn5tb
4. Insertion in B strain and DNA duplication event in K12.	Prophage DNA and transposase insertion	Recent DNA duplication event	100% identity between paralogs and ~98% identity between syntenic region in REL606	Possible phage DNA insertion in REL606 as "hypothetical protein" genes were found near putative prophage tail component gene in REL606.	tinyurl.com/yea8bu6
5. Insertion	Bacteriophage DNA insertion	IS2 sequence insertion	Pseudogenes at IS2 insertion site in DH10B. Phage specific genes were found in REL606	Possible phage DNA insertion in REL606 as "Hypothetical proteins" were found near phage specific genes	tinyurl.com/yevlb2w
6. Insertion	Prophage DNA insertion	none	Phage specific genes were found in REL606	none	tinyurl.com/ybokuag
7. Insertion	none	Prophage DNA insertion	Phage specific genes found in DH10B	none	tinyurl.com/yaxlh7o
8. Insertion and deletion	Transposon insertions and deletion of phenylacetic acid degradation genes	IS and Rac prophage DNA insertion	Phage specific genes found in DH10B. IS insertions in REL606 might have created direct repeats and facilitated excision of phenylacetic acid degradation genes.	Rac prophage DNA disrupted by transposon insertion in DH10B	tinyurl.com/yccbmsq
9a. Insertion 9b. Insertion 9c. Insertion 9d. Insertion	9a. none 9b. Insertion of ISI transposon 9c. none 9d. IS2 insertion	9a. Insertion of IS5 sequence 9b. none 9c. Insertion of ABC transporter, flagella encoding genes and few other enzymes 9d. none	9a. none 9b. none 9c. Inserted DNA segment in DH10B is bordered by direct repeats at both ends. 100% identity was found between the two repeats.  9d. none	9a. none 9b. none 9c.DR indicates transposon insertion in DH10B.  9d. none	9a. http://tinyurl.com/ylllc6u 9b. tinyurl.com/ygsqg2f 9c. tinyurl.com/ykypc67 9d. tinyurl.com/ygfgtqy
10. Insertion and deletion	Bacteriophage DNA insertion and IS1 transposon insertion. Deletion of metal resistance genes	Insertion of pili associated genes	Insertion of pili associated genes in DH10B as evidenced by their different GC codon	No IR were found as to indicate insertion of genes conferring metal resistance in DH10B. Possible deletion in REL606 of these genes prior to IS1 transposon insertion.	http://tinyurl.com/yammj7v tinyurl.com/ykvvvk2
11. Insertion	IS1 insertion followed by insertion of ParB family protein genes and recombinase.	CP4-57 prophage DNA insertion	Different GC content of ParB family protein and recombinase gene indicates that these genes were acquired by exogenous DNA such as plasmid possibly by homologous crossover as no IR were found.	IS1 insertion probably occured independent of integration of other genes in REL606.	http://tinyurl.com/ycdog2c
12. Insertion, deletion and Inversion	IS1 insertion. Insertion of pyrophosphorylase and "hypothetical protein" genes	IS5 and IS10 transposon insertion. Inversion of ornithine decarboxylase, M-type protein and bifunctional prepilin peptidase/methylase. Deletion of saframycin synthetase, capsule related genes, bio-film formation genes, anti-toxin system and type II secretory apparatus genes.	Insertion of pyrophosphorylase and "hypthetical protein' genes in REL606 as evidenced by their different GC content Inversion in DH10B as evidenced by IR of IS10 transposon. Deletion of several genes in DH10B is evidenced by IS5 transposase transactivator.	No evidence of insertion	http://tinyurl.com/ycoagxh
13. Insertion of transposon, ShiA-like, TrbC-like proteins in B strain.	IS30 transposon insertion in B strain. Presence of ShiA-like and TrbC-like protein in B strain				http://tinyurl.com/ydkrcv8
