摘要
林木种质资源丰富,种质间遗传差异大,控制林木重要性状的基因克隆及转化对培育优良林木新品种具有很强的实用价值,但许多具有潜在应用价值的林木基因未得到充分发掘和有效分离。近年来,随着各种不同林木cDNA文库的建立,大规模随机EST测序技术的运用以及克隆技术的不断完善,特别是毛果杨(Populustrichocarpa)基因组测序计划的完成,大量与林木重要性状相关的基因被分离和鉴定。这些重要基因的获得为利用转基因技术培育高产、优质、抗逆、抗病虫害的林木新品种奠定了一定的基础。该文综述了20多年来国内外林木基因克隆的研究进展,对基因克隆及其应用过程中亟待解决的问题进行了讨论,并对其发展趋势进行展望。
