摘　　要：微藻储能物质(碳水化合物、脂类等)可以作为生物燃料和生物基化学品的可再生原料。非生物胁迫(高光强、高盐度、营养盐限制、重金属等)传统诱导微藻储能物质积累的方法影响微藻的生长,从而限制了储能物质的高效积累。植物激素作为化学信使协调植物细胞活动的一类小分子物质,可对微藻的生理代谢活动产生调控作用,包括促进微藻细胞分裂,增加胁迫耐受,提高光合作用效率,从而提高藻类生物量,增加油脂、叶绿素和蛋白质含量。本文中,笔者概述了近年来国内外利用外源添加植物激素结合非生物胁迫条件调控微藻储能物质积累的研究进展,探讨了植物激素对微藻储能物质积累的作用机制,并提出未来可能的研究方向。Microalgae energy-storage compounds(carbohydrates,lipids,etc.)can be used as renewable feedstock for biofuels and bio-based chemicals.Traditional methods of inducing the accumulation of energy-storage compounds in microalgae,such as abiotic stress(high light intensity,high salinity,nutrient limitations,heavy metals,etc),affect the growth of microalgae,thus limiting the efficient accumulation.Phytohormones are a class of small-molecular substances that coordinate plant cell activity as a chemical messenger,to regulate the physiological and metabolic activities of microalgae,including promoting microalgal cell proliferation,improving stress tolerance,elevating photosynthetic activity,and thus increasing algal biomass production and lipid,chlorophyll and protein content.We review the research progress in regulating the accumulation of energy-storage compounds in microalgae by adding exogenous phytohormones combined with abiotic stress in recent years,and discuss the mechanism of phytohormone on the accumulation of energy-storage compounds in microalgae,and propose the future research needs.
