Base composition of mGing TIR sequence. (a) Distribution of mGing sites on the Nipponbare chromosomes. The locations of mGing are shown as single red lines. Map positions were obtained through the sequence homology search against the rice genome. (b) GC content analysis of mGing insertion sites. The blue line and the red line respectively indicated the average GC content of the sequences near mGing locations and sequences randomly selected from rice genome. (c) Base composition analysis of mGing TIR. Pictograms were constructed by using the 18 nucleotides extracted from the 5' or 3' ends of 1055 full-length mGing HSPs. The gray box indicated 15 bp TIR sequence of mGing.
