The Recent Progress on Breeding by Spaceflight Mutagenesis

In the past few years, spaceflight mutation breeding has become a big characteristic in the study of space life science. A lot of new high-produced and well qualitative cereals, flowers and antibiotics have been bred by the technique of spaceflight mutation breeding home and abroad. The variations are produced in many organisms travelled by satellite by means of the comprehensive effect like high vacuum, microgravity, insense radiation and so on. Recently a new kind of mutagenic mechanism was found, which is theory of transposon. Transposon is activiated and the mutation happens in the organism. Spaceflight mutation breeding opens up a new way for the breeding.
