摘要

The future of humankaind greatly depends on a sufficient and stable food supply. The most effective way of achieving this is to develop cultivars with superior agronomic characteristics, especially high yield. As described above, a marked increase in grain yield in rice and wheat will probably be difficult if we continue semidwarf crop breeding utilizing existing semidwarfing genes, viz.，sd1 and sd9 in rice, and Rht1 and Rht2 in wheat (Gale 1985). Thus, it is very important to exploit other useful genes related to yield and other agronomically important traits. In this report, we show that a great variety of mutations, including novel gene mutations, can be induced by mutagenic treatment. We propose that we should attempt to induce a great number of mutant genes as well as to identify useful genes from existing genetic resources, and that we should collect and stock these mutants at a research institute in charge. We have described the mPing transposon in detail in this report. As discussed here, transposable elements and other repetitive sequences are involved in gene and genome restructuring and in gene regulation (Tomita and Tanisaka 2010). For this reason, the use of transposable elements should be considered in future plant breeding efforts.
