摘要
木麻黄科植物具有特殊的生物学特性、较高的经济价值和广泛的社会效益,作为重要的防护林、用材林和多用途林树种,是重要的热带林木种质资源。由于可持续性发展的需要,木麻黄研究越来越受到人们的重视,木麻黄遗传改良方面已取得显著成果。近十年来分子生物学技术的飞速发展,尤其是植物基因克隆和转化研究的日新月异,极大地促进了木麻黄转基因研究的发展,缩短了木麻黄育种改良周期,为木麻黄—微生物共生体研究提供了有效的方法。木麻黄分子生物学研究始于20世纪80年代晚期,主要进行了木麻黄细胞学基础、种群遗传多样性、固氮基因分离和克隆、基因转移等方面的研究,目前已取得了令人瞩目的成果。文章综述了国内外木麻黄科植物在分子生物技术方面的研究及进展,提出了该领域研究的需求和前景,以期对该领域的深入研究起到积极的促进作用。
With special biological characteristics, Casuarinaceae plants had high economic values and extensive social benefits, as an important forest germplasm resource in tropical region, they could be used as shelter belt trees, industry plantation trees and multiple purpose plants. To meet the requirement of sustainable development, casuarina research had been paid much attention. Currently, studies in genetic improvement had gained many achievements. With the fast development of molecular biotechnology last ten years, especially the research of gene clone and transformation of plants change quickly, people greatly promoted the development of gene transformation and relative biotechnology so that the cycle of breeding and improving of Casuarinaceae plants can reduced. The gene transformation also provide an effective method for the research of Casuarinaceae - microbe symbiosis. The biotechnology research on Casuarinaceae plants began at late eighties of the twentieth century, such as elements of cytology, genetic diversity,isolate and clone of nitrogen - fixation gene and gene transformation, and had achieved lots of achievements. This paper summarized the advances of biotechnology research on Casuarinaceae both in China and abroad, put forward the further requirement and prospect in order to soeed up the development in this field.
