Overview of bacterial phenotypes associated with the mutation of bacterial expansins.

Bacteria	Lifestyle	Primary route of colonization	Protein structure	Gene	% identity^a	Expansin mutant phenotype		Reference
Bacteria	Lifestyle	Primary route of colonization	Protein structure	Gene	% identity^a	Disease symptoms	Root attachment	Reference
Clavibacter michiganensis subsp. michiganensis	Vascular phytopathogen	Foliar	Non-chimeric	CmEXLX2	100 (100)	Increase	No difference	This study
Clavibacter michiganensis subsp. michiganensis	Vascular phytopathogen	Foliar	Chimeric	CmEXLX1	17 (54)	Decrease	n/a	(Jahr et al., 2000)
Ralstonia solanacearum	Vascular phytopathogen	Root	Non-chimeric	RsEXLX	27 (34)	Decrease	Hyper-attach	This study

Percent amino acid identify of the full-length protein, relative to the non-chimeric Clavibacter michiganensis subsp. michiganensis expansin CmEXLX2. The number in parenthesis denotes the amino acid identity of the most similar regions via the pairwise sequence alignment tool EMBOSS Matcher (Goujon et al., 2010).
