There is, however, no genetic transformation method for it. Here we report the development of an efficient mutagenesis method based on Agrobacterium tumefaciens-mediated transformation. To improve transformation efficiency, a range of conditions, including the codon-usage preference of the selection marker gene, promoters and the culture conditions for transformation were optimized. A strong promoter to drive marker gene expression, optimized codon usage of selection marker gene, controlled water content and pH of co-culture medium were critical factors affecting transformation efficiency. Our findings provide a useful tool for genetic analysis of this important plant pathogen. © 2014 Springer Science+Business Media Dordrecht.||Source Title:||Biotechnology Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/116401||ISSN:||15736776||DOI:||10.1007/s10529-014-1486-5|
