摘要
胡杨具有抗盐碱、抗旱等特性,是极端干旱沙漠地区唯一的乔木树种,对于维持荒漠地区生态平衡具有重要作用。胡杨对多种逆境的高抗性和良好适应性成为近年来研究的热点。关于胡杨分子生物学方面的研究,相对于其他模式植物研究开展较晚。文中综述了近年来国内外胡杨分子生物学研究的阶段性进展,包括分子标记开发、遗传多样性检测、基因组和转录组的研究以及重要的抗逆相关功能基因的分析等;讨论了目前胡杨分子水平研究存在的不足,并对胡杨分子生物学研究的发展前景作出展望,旨在为胡杨的保护和育种提供更多的科学参考。
Populus euphratica is the only tree species that can survive in the extremely dry desert areas with its high resistance to alkali and drought,which has an important function in maintaining the eco-balance in the desertified areas. Its high resistance to multiple stresses and good adaptability makes it a research focus in recent years. The paper reviewed the phased research progress in its molecular biology at home and abroad,including molecular markers development,genetic diversity testing,genome and transcriptome analysis,characterization of key functional genes related to stress resistance. Finally we discussed the problems existing in current research and prospected the future development direction of molecular biology research. This study was aimed at providing more scientific references for the protection and breeding of P.euphratica.
