摘要:
极地环境是一个潜在的、重要的微生物资源库,极地环境生物资源的开发与利用已成为全世界高度关注的热点。微藻作为极地环境中最主要的初级生物量生产者,其种质资源的选育、培养及抗逆性研究倍受关注。低温、季节性光照与温度波动、强紫外(UV)辐射等是极区生境重要的环境特征。极地微藻经过长期的适应与进化对该生境形成了独特的适应机制:其细胞内合成积累多种具有特殊生理、药理活性的生物活性物质,以及蕴含与之相对应的新基因。本文综述了南、北极地区的微藻抗逆机制的最新研究进展,包括对温度、光照和UV辐射胁迫的生理和分子抗逆机制,以及组学技术在微藻逆境生物学上的应用,有助于人们了解极地微藻适应极端逆境的机制及其在极地生境中独特的系统进化地位。
Abstract:
Since polar region is an important potential resource of microorganisms,the researches on its bioresource exploration and utilization has become one of the global hot issues. Microalgae is the primary biomass producer of polar region,and the studies on the strain breeding,cultivation and stress-resistant mechanisms of polar algae has attracted strong interests of scientists. The polar habitat is characterized by freezing temperature,seasonal variation of irradiation and temperature,strong ultraviolet(UV) radiation,and so on. Polar microalgae develop unique adaptive mechanisms to such extreme environment in the progress of long-term acclimation and evolution. The synthesis and accumulation of special physiological or pharmacological bioactive compounds,and induction of stress-resistant novel genes enable polar algae to survive the extreme polar region. This paper aims to review the recent research progress on the stress-resistant and adaptive mechanisms of microalgae from Antarctic and Arctic region in response to temperature,irradiation and UV radiation,and provides a summary of the application of various omics technology on microalgae stress biology. This review will help us better understand the underlying adaptive mechanisms of microalgae to extreme stresses,and reveal the unique phylogenetic role of microalgae in polar ecological system.
