摘　要：

逆境胁迫生理是当前植物生理学研究的热点领域。作为世界上重要的经济海藻之一, 紫菜养殖量逐年增加。但是由于紫菜主要生长于潮间带或者低潮带区域, 海水环境中各种非生物胁迫是影响紫菜产量的重要威胁。近年来, 随着mRNA差异显示、抑制消减杂交、cDNA代表性差异分析等技术的发展, 国内外学者围绕紫菜抗逆生理的基因调控机制展开了一系列的研究, 取得一定的科学认知。本文综述了紫菜在高低温、干出、光照、营养盐与重金属等胁迫因子影响下的生理生化特征及其抗逆调控机制等方面的主要研究进展, 提出了研究展望。本研究拟为今后改良紫菜抗逆性的遗传育种工作提供参考。

Abstract:

Adversity stress is one of the hot topics in plant physiology research at present. Since laver has been one of the most important economic algae in the world, the cultivation of which has been increasing year after year. However, because laver mainly grows in intertidal zone or lower intertidal zone, abiotic stress is an important threat to seaweed yield in seawater environment. In recent years, with the development of the technology of mRNA differential display (DDRT-PCR), suppression subtractive hybridization (SSH) and cDNA representative differential analysis (cDNA RDA), scholars at home and abroad have carried out a series of studies on the mechanism of gene regulation in laver resisting to adverse conditions, and the results made a certain contribution to scientific cognition. In this paper, the main research progress on the physiological and biochemical characteristics of laver under the stresses of temperature, drought, nutrient, salt and heavy metal, as well as the regulation mechanism of adversity were reviewed. This paper could give a reference to genetic breeding for improving the resistance of laver.

Key words: laver; physiology under stress resistance; regulation mechanism
