A putative autonomous 20.5 kb-CACTA transposon insertion in an F3'H allele identifies a new CACTA transposon subfamily in Glycine max.

ABSTRACT:

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.

Results

We identified a 20.5 kb insertion in a soybean flavonoid 3'-hydroxylase (F3'H) gene representing the t* allele (stable gray trichome color) whose origin traces to a single mutable chimeric plant displaying both tawny and gray trichomes. This 20.5 kb insertion has the molecular structure of a putative autonomous trans
