    RYS1, a foldback transposon, is activated by tissue culture and shows preferential insertion points into the rye genome

    The study of two variable amplicons of rye indicates that RYS1, a mobile element, is activated during tissue culture. We propose that RYS1 could be a foldback (FB) transposon. The FB transposons have been rarely ...
