香蕉抗寒相关功能基因研究进展

Research Progress on Banana Functional Genes Involved in Cold Resistance

香蕉是世界上产量最大的三大水果之一,也是世界上第四大粮食作物。低温是影响中国香蕉生产的重要因素之一,尤其是除海南和广东西南等地区外的香蕉产区常年遭遇冬春寒流侵袭。近年来随着抗寒基因工程的发展,有关香蕉抗寒性的分子水平研究得到了较大进展。本文从香蕉抗寒相关的功能基因入手,归纳了近几年国内外关于香蕉的抗寒相关功能基因(冷胁迫相关蛋白基因,膜脂相关蛋白基因,抗氧化酶基因等)研究并提出了展望,旨在为香蕉抗寒主效基因资源的发掘及香蕉抗寒品种的选育提供思路。

As one of the three largest fruit producer, banana is also the fourth food crops in the world. Low temperature was one of the important factors affecting the banana production in China. In particular, the cold snap in winter and spring hit the banana production area throughout the year except Hainan and the southwest of Guangdong regions. In recent years, with the development of cold-resistant genetic engineering, the research on molecular level of cold resistance of banana has achieved great progress. This article started with the cold-resist functional genes of banana and summed up domestic and foreign researches about the related functional genes of cold-resist banana（such as： the cold stress-related protein gene, membrane lipid associated protein, antioxidant enzyme gene） and also put forward a prospect, which aims to provide some ideas to the excavation of banana cold-resistant main-effect gene resources and breeding of banana anti-cold variety.
