香蕉生物技术研究进展

近50年来香蕉的生产得到了稳步的发展,同时正遭受越来越严重的病虫、霜冻和台风的侵害。鲜食蕉雌雄性高度不育的特性,使得传统的育种方法难以进行香蕉的遗传改良。这些现状迫切要求香蕉生物技术的不断发展和深入。近10年来,在香蕉体细胞胚胎发生、原生质体培养、基因克隆和序列分析以及基因转化等方面都取得了可喜的成果,并预计于2006年完成香蕉基因组的测序 。

Recent Progress in Biotechnological Research on Bananas

Banana is one of the most important fruit crops in the world,and it is a staple food for about 500 millions people in developing countries.In recent 50 years,the production of banana has been developed.At the same time,it is encountering more and more serious attacks from diseases,pests,and stress of frozen and wind.Banana's improvement by traditional breeding procedures has not been very successful because of its sterility.All these status demands continuous biotechnological research on banana.In recent 10 years,a number of biotechnological tools have been developed,including sequencing the entire banana genome,gene transformation and so on,which could help breeders with developing new banana cultivars to meet the demands for the banana production and markets.Recent developments in biotechnological research on banana and the future of banana biotechnology are outlined.;
