摘要
综述了近年来国内外核果类果树转基因的研究进展,涉及的内容有:用农杆菌转化核果类果树中难生根种类,获得易繁殖的转化植物;转移病毒外壳蛋白基因和杀菌毒性肽基因以提高抗病性;转移细胞分裂素基因和光敏素基因改良品种或砧木生长特性,培育紧密型的、短枝的、矮化半矮化的新品种;转移抗冻基因提高抗霜冻性;通过反义转基因技术调节果实的成熟,获得耐贮运的新性状,以及核果类果树基因转化技术的发展等方面。
The advances in transgenic research on stone fruit trees(apricot,cherry,plum,almond,peach,nectarine ect.)were re-viewed in this paper.The main contents include creating chimeric plants for easier propagation of difficult-rooting species by a-grobacteria transformation,in creasing resistance to disease by transformation with virus coat protein genes,in troducing cy-tokinin genes and phytochrome genes to improve growth habit,enhancing cold resistance by transformation with an tifreeze genes,block ing fruit ripening by antisense technology,and development oftransformation methodologies ofstone fruit trees.
