Characterization of three active transposable elements recently inserted in three independent DFR-A alleles and one high-copy DNA transposon isolated from the Pink allele of the ANS gene in onion (Allium cepa L.).

Abstract excerpt

Intact retrotransposon and DNA transposons inserted in a single gene were characterized in onions (Allium cepa) and their transcription and copy numbers were estimated in this study. While analyzing diverse onion germplasm, large insertions in the DFR-A gene encoding dihydroflavonol 4-reductase (DFR) involved in the anthocyanin biosynthesis pathway were found in two accessions. A 5,070-bp long terminal repeat...
