Genome-wide mutagenesis of Zea mays L. using RescueMu transposons

Genome Biol. 2004;5(10):R82. doi: 10.1186/gb-2004-5-10-r82. Epub 2004 Sep 23.


Derived from the maize Mu1 transposon, RescueMu provides strategies for maize gene discovery and mutant phenotypic analysis. 9.92 Mb of gene-enriched sequences next to RescueMu insertion sites were co-assembled with expressed sequence tags and analyzed. Multiple plasmid recoveries identified probable germinal insertions and screening of RescueMu plasmid libraries identified plants containing probable germinal insertions. Although frequently recovered parental insertions and insertion hotspots reduce the efficiency of gene discovery per plasmid, RescueMu targets a large variety of genes and produces knockout mutants.
