A putative autonomous 20.5 kb-CACTA transposon insertion in an <Emphasis Type="Italic">F3'H</Emphasis> allele identifies a new CACTA transposon subfamily in <Emphasis Type="Italic">Glycine max</Emphasis>

Background  

The molecular organization of very few genetically defined CACTA transposon systems have been characterized thoroughly as those of Spm/En in maize, Tam1 of Antirrhinum majus Candystripe1 (Cs1) from Sorghum bicolor and CAC1 from Arabidopsis thaliana, for example. To date, only defective deletion derivatives of CACTA elements have been described for soybean, an economically important plant species whose genome sequence will be completed in 2008.
