【摘要】 林木作为重要的可再生自然资源,具有良好的经济效益、生态效益和社会效益。林木遗传改良在森林资源可持续发展中起到关键作用,现代分子生物学技术的迅速发展为之带来了新的机遇和挑战。近年来,林木生物技术研究取得了重要突破,显示出独特的优势和巨大的发展潜力。转基因林木的遗传稳定性在田间试验中得到验证,遗传基因组学和关联遗传学的发展也为进一步深入开展林木遗传改良研究提供了新思路。杨树全基因组测序计划的完成实现了多年生木本植物基因组的首次破译,势必开启林木分子育种的新时代。综述当前林木遗传改良中的分子生物学研究进展,遗传基因组学和关联遗传学策略在林木育种中的应用;并就林木分子生物学研究中亟需解决的问题和应用前景进行讨论。更多还原

【Abstract】 As important renewable natural resources,forest trees have a huge economic,ecological and social value.Genetic improvement programs play a crucial role in the sustainable management of forest resources.The rapid development of modern molecular biotechnology brings us new opportunities and challenges in forest tree improvement.Forest biotechnology has already shown great application potential for forest tree improvement.Not only has the potential been demonstrated in producing transgenic trees with optimized yield and quality traits in field trials,but progress in genetical genomics and association genetics provide new thoughts for tree improvement.The availability of Populus genome sequence will develop new domain in the tree molecular breeding.In this paper,we reviewed molecular biology applied in the improvement process of forest tree,together with two main avenues,genetical genomics and association genetics,to accelerate forest tree improvement.Moreover,the existing problems and the perspective of applications of molecular biotechnology to tree genetic improvement were also discussed.更多还原
