红树植物的分子生物学研究进展

Progress of Molecular Biology Research on Mangrove Plants

红树植物是生长于热带、亚热带陆海交汇的海湾河口潮间带的盐生木本植物群落,物种多样性丰富,生态价值高,蕴藏着丰富的热带特色基因资源。分子生物学及其技术的产生和发展,为开发和研究红树植物资源奠定了基础。近年来,RAPD、RFLP、ISSR、蛋白质双向电泳等分子生物学技术的应用,使红树植物的研究和利用取得了重大进展。本文将从红树植物的分子生态学、红树植物的遗传多样性、红树植物耐盐基因的分离克隆、及利用红树耐盐基因进行分子育种等方面展开综述,探讨近年来红树植物的分子生物学研究进展。

Mangroves, the woody plants occurring primarily in the tropical intertidal regions of the world, are valuable natural resources with abundant biodiversity, significant ecological effect, and contain plentiful gene resources with tropic particularity, such as salt-tolerant genes. The developments of molecular biology and its techniques lay a good foundation for better studying and exploiting mangrove plants. In recent years, with the applications of molecular biological techniques and methods including RAPD, RFLP, ISSR, protein two-dimension electrophoresis, and so on, a great deal of gratifying progress have been made in mangrove plant researches. In this article, we reviewed and discussed the molecular biology progress in mangrove plant from following aspects: molecular ecology, genetic diversity, isolating and cloning of salt-tolerant genes, and molecular breeding progress using mangrove plant gene resources.
