摘　　要：香蕉是世界上最受欢迎的水果之一,也是第四大粮食作物,低温是影响其种植区域、生长发育、产量和品质的重要环境因素。近年来,随着基因组学和蛋白质组学等分子生物学技术的深入发展,香蕉抗寒分子机制的研究取得了较大进展,笔者重点从生物膜、磷酸化信号通路、基因表达、蛋白表达4个层面综述香蕉品种抗寒性差异的分子机制和调控途径,旨在为香蕉抗寒品种的培育和栽培措施的改进提供理论参考。Banana(Musa ssp.) is one of the most popular fruits in the world and the fourth largest food crop after rice, wheat and corn. It has become an important food and economic crop in sub-Saharan Africa, South and Central America, and Asia. Bananas are originated from tropical regions, the main cultivated bananas prefer high but do not low temperature, and are sensitive to cold stress. The optimum growth temperature for bananas is 24-32 ℃, and the growth will be blocked or even stagnated under 10-12 ℃. When the temperature drops to 1-2 ℃, the plants will suffer serious damage or even die.Therefore, low temperature is an important environmental factor affecting its planting area, growth development, yield and quality. Banana planting areas in China are mainly located in the southern subtropical regions, including Guangdong, Fujian, Guangxi, Yunnan, Hainan and other provinces. Banana has become an important source of economy in our country’s southern subtropical regions and has played a key role in promoting rural economic development, agricultural efficiency, and farmers’ income. However, with global climate change, cold spells often occur during winter or early spring, which can have a serious impact on banana production, and restrict the healthy development of the banana industry. Cultivating new cold-tolerant bananas has become one of the urgent problems in the development of banana industry in China. For a long time, triploids and extremely low fertility of most banana cultivars limit the improvement of cold-tolerant bananas through traditional breeding. Banana molecular breeding provides an effective method for creating new banana germplasm with enhanced cold tolerance. The cold tolerance of banana germplasms is quite different. The main cultivated Cavendish banana(Musa AAA Group), which has a good flavor and taste, is cold-sensitive, but the relative germplasms such as Dajiao(Musa ABB Group) and Pisang Awak banana(Musa ABB group) are more tolerant to low temperatures of 0-4 ℃. These cold-tolerant bana
