沙棘(
Hippophae rhamnoides)属于灌木或小乔木,是集生态经济社会效益于一身的树种。在实际生产中,由于沙棘自然生长区水分制约,导致沙棘产业化发展严重受到限制。前人对沙棘抗旱的研究主要集中在抗旱途径及生理生化指标等方面,有关沙棘抗旱性分子机制和在沙棘中挖掘抗旱基因的研究为空白。因此本文从抗旱研究方法和干旱胁迫对沙棘生长发育、生理生化、抗旱基因等进行综述,并对挖掘沙棘抗旱基因研究进行了展望,为深入沙棘抗旱研究提供依据。
Hippophae rhamnoides, a deciduous shrub or dungarunga, has comprehensive advantages including ecological, economic and social benefits. Nevertheless, due to the water restriction in the natural growth zone of
Hippophae rhamnoides, the development of industrialization of
Hippophae rhamnoides is severely limited in actual production. At present, the ways of drought-resistant and the changes of its physiological and biochemical indexes are emphasized in the study of drought-resistant mechanism of
Hippophae rhamnoides. However, the researches on the molecular mechanisms and genes of drought-resistant of
Hippophae rhamnoides have not yet been involved. Therefore, the two aspects of drought-resistant of
Hippophae rhamnoides had been discussed in this review, one of which was the drought-resistant research method, the other part was the impact of drought stress on its growth and development, physiological and biochemical, drought-resistant genes, etc. At the same time, the research on the drought-resistant gene was also expected to provide the basis for further study on the drought-resistant mechanism of
Hippophae rhamnoides.
