Outline of Final Research Achievements |
We find monosomy silkworm individuals which are reproducible and have both female and males. By crossing two mutant strains with the monosomy individuals we developed monosomy strain that can be discriminated by the visible phenotypes. RNAseq revealed that the expression of 2nd chromosome genes in the monosomy progenies seems to be about half amount that in the normal. Hence we concluded dosage compensation for the autosome gene cannot be functioned in the silkworms.
