| Research Abstract |
In the survey using a stress-fluctuation cDNA browser afforded by high-throughput sequencing, several kinds of transposon-like elements were preferentially discovered in novel active transcriptional regions. Almost of the elements were inactivated by cryptic splicing which was inhibited by extreme stress. An intensity of mature polyadenylation to the mRNA of a novel DNA transposon AoTanl increased under stress conditions. It was suggested that mature and active mRNA molecules of transposon-like elements tended to be increased during the extreme stress, resulting in genetic diversity by transposable elements in Aspergillus oryzae.
