CORRIGENDUM
Are all horizontal gene transfers created equal? Prospects for mechanism-based studies of HGT patterns, by J. R. Zaneveld, D. R. Nemergut and R. Knight
Microbiology vol. 154, part 1, pp. 1 - 15
Subsection 'Generalized Transduction' (page 7 of printed article)
The statement 'Following infection of a new bacterial host, this extra genetic material can be integrated alongside the phage genome', should be replaced by: 'Following infection of a new bacterial host, this extra genetic material may be incorporated into the recipient bacterial genome by homologous recombination, although this is only observed at appreciable frequencies in internal deletion mutants of Mu (mini-Mu), where the quantity of flanking host DNA packaged is correspondingly greater (Faelen et al., 1979).'
Table 2 (page 5 of printed article)
The entry for 'Gene transfer agents' should be relabelled 'Generalized transduction, including by gene transfer agents', and the row labelled 'Generalized transduction' should be deleted.
Subsection 'Transposition' (pages 10-11 of printed article)
Second paragraph. The sentence 'ISs . . . consist of a transposase gene (either a serine or DDE recombinase)' should be expanded to '. . . (a serine, tyrosine or DDE recombinase) . . .'
Third paragraph. The sentence beginning 'In contrast, replicative transposons are first copied . . .' should be amended to read: 'In contrast, replicative transposons are copied during the process of transposition to a distal site in the genome . . .'.
ACKNOWLEDGEMENTS
We would like to thank Arianne Toussaint for bringing these issues to our attention, and for a very spirited and stimulating discussion of many aspects of Mu phage biology.
