    摘要:

    甘蔗是世界上重要的糖料和能源作物。我国食糖产量居世界第三,其中九成以上的食糖来自于甘蔗产糖,由此可见,甘蔗对于我国食糖产业具有举足轻重的作用。目前,我国已成为世界第二大食糖消费国,随着我国经济社会高速发展和人民生活水平的不断提高,食糖需求还将不断增长。但是,由于城镇化进程的加快和其它作物竞争的加剧,甘蔗种植面积正不断减少,呈现出向高海拔、土壤贫瘠等生产条件差的地方转移的趋势,因此遭受的逆境胁迫程度日益加深,严重影响了甘蔗的生长发育及产量形成。如何解决逆境胁迫下甘蔗的产量问题是目前生产上面临的重要课题。目前最好的解决办法还是培育高抗逆境品种,为了给甘蔗抗性品种选育提供参考,本文对甘蔗的各种逆境,如低温、干旱、高盐、重金属等伤害与抗逆性的生理生化机制及甘蔗抗逆相关功能基因的挖掘研究进行了综述,以期系统清楚地了解甘蔗逆境研究现状,为甘蔗抗逆相关研究方向的设定、分子机理和新品种的选育提供借鉴。

    Abstract:

    Sugarcane is a worldwide important crop for sugar and bio-energy. China produces third most sugar in the world, of which more than 90% was from sugarcane. Therefore, sugarcane plays a key role in China sugar industry. China has become the second largest sugar consumer in the world, and its rapid-developing economy, society, and living standard are driving an increasing demand for sugar. However, its sugarcane production area is in reduction caused by accelerated urbanization and extensive crop competition. A tending that sugarcane production region are moving to poor environments such as high altitude and barren land can be observed. As a result, the plants are growing under more and more stress, which seriously impacts the development and yield. Improving yield in stressed environment has become an important chanllenge for sugarcane industry. Breeding for varities with enhanced resistance has been demonstrated one of the best solution. In this paper, bio-chemical and physiological mechanism involved in harm and resistance to various abiotic stress, such as low temperature, drought, salt, heavy metal, were presented. Progress in functional gene mining related to these resistance was reviewed. The aim of this work was to offer a systemic and precise description of the research progress to abiotic stress, and thus to provide reference for studies on molecular mechanism responsing stress and breeding for robust varities.
