摘要
综述了近年来植物远缘杂交受精后生殖障碍的研究进展,对胚降解和杂种不育的特征特性与产生机理进行了分析;重点阐述了克服植物远缘杂交受精后生殖障碍的方法,包括幼胚拯救(子房、胚珠和胚培养)以克服胚败育、染色体加倍以克服杂种不育及化学处理、回交等其他方法;最后指出利用蛋白质组学技术并整合分子生物学研究手段,以阐明胚胎败育的分子机理,应是未来植物远缘杂交研究的重点方向。
The research progress of distant hybridization in the field of plants breeding in recent years was re -viewed comprehensively .The characteristics and mechanisms of post-fertilization barriers were analyzed on the view of embryo abortion and hybrid sterility .Meanwhile ,the effective methods to overcome these barriers were mainly re-viewed,including embryo rescue(Ovary,ovule and embryo culture) to prohibit its abortion,doubling chromosomes to restore its fertility and other methods such as chemical treating and back-crossing.At last,the future research em-phasis in this field was suggested as revealing the molecular mechanism of embryo abortion in distant hybridization by using the proteomics combined with molecular physiological methods .
