离子束辐照拟南芥生物学效应及其分子机理研究进展

综述了离子束辐照拟南芥种子生物学效应、 生长发育变化、 向重力性等研究的最新进展。 阐释了离子束辐照拟南芥染色体DNA碱基变化、 DNA断裂或损伤、 染色体重组、 突变遗传性等分子机理。 探讨了离子束介导外源基因转化拟南芥的有效性和机理。 同时展望了辐照拟南芥分子机理研究中的辐射原初效应传递、 信号转导等其他机理研究及重离子辐射生物学效应的应用前景。 Newly research progresses were summarized in effect of ion beams on seed surface， biological effect， growth， development， gravitropism and so on. Furthermore， mutation molecular mechanism of Arabidopsis thaliana was discussed， for example， alteration of DNA bases， DNA damage， chromosomal recombination， characteristics of mutant transmissibility， etc. Meanwhile， the achievements of transferring extraneous gene to Arabidopsis thaliana by ion beams were reviewed in the paper. At last， the future prospective are also discussed here in mutation molecular mechanism and the potential application of biological effect of heavy ion beams.
