林木非生物胁迫抗性基因工程研究进展

Progress in Genetic Engineering of Forest Trees Under Abiotic Stresses

干旱、极端温度和盐害等非生物胁迫因子是制约林木生长的重要因素。由于林木生长周期长,且抗逆机制极为复杂,长期以来,如何改良林木对非生物胁迫的抗性一直是育种学家的难题。然而,随着基因工程技术的发展,人们可以在基因水平上改造林木,提高其抗逆能力。文中主要介绍了林木抗逆基因工程的研究进展,探讨了目前基因工程技术应用于林木抗逆育种研究存在的问题,并对其应用前景进行了展望。

Abiotic stresses such as drought, extreme temperature and salt injury are important factors limiting the growth of forest trees. Due to long cycle of forest trees growth and complicated mechanism of resistance, to improve forest trees resistant to abiotic stresses has been a difficult problem to forest breeders. With the development of genetic engineering technology, forest trees could be improved at the gene level and increase the resistance ability. This paper mainly describes the progress in genetic engineering of forest trees under abiotic stresses and discusses the existing problems in researches of forest breeding for abiotic stresses by using genetic engineering technology. Moreover, the prospect of genetic engineering technology for the application of forest trees breeding for abiotic stresses are presented in this paper.
