能源植物小桐子抗逆性研究进展

The Research Progress on Stress Resistance of Energy Plant Jatropha curcas L.

随着化石能源的逐渐消耗,寻找更加生态、可持续再生的替代能源成为未来的发展方向。小桐子作为一种新兴的能源植物,因其种子含油量高,可制备生物柴油等方面的特性而备受关注。逆境不仅限制小桐子的地域分布,而且对小桐子的产量及品质的形成有重大影响。为此,对小桐子的各种逆境,如低温、干旱、高盐、高温、重金属等伤害与抗逆性的生理生化机制进行了综述。在此基础上,对小桐子抗逆相关功能基因的克隆及技术进行了总结,以期为今后小桐子抗逆性分子机理研究及新品种的选育提供借鉴。

As the consumption of fossil fuels, looking for a form of ecological, sustainable and renewable energy source is nowadays a hot spot. Jatropha curcas L., a newly developed energy plant, has gained much attention for its high oil content in seed and can be used as biodiesel. Stresses not only have great restriction on the region distribution of J.curcas, but also have important influence to the formation of J.curcas output and quality. This paper mainly reviewed the physiological and biochemical mechanism of stress resistance from cold, drought, salt, high temperature and heavy metals. In the end, the author gave a summary on cloning of resistance-related functional genes and transgenic techniques, in order to promote the improvement of J.curcas molecular mechanism of resistance and the breeding of new varieties.
