| 摘 要： | 虾青素是一种具有强抗氧化活性的类胡萝卜素,而雨生红球藻是天然虾青素的主要来源。本文以雨生红球藻(Haematococcus pluvialis)为材料,研究了植物激素玉米素和水杨酸对雨生红球藻的生长、虾青素含量及相关基因表达的影响。分别添加5种浓度的玉米素或水杨酸,结果发现0.05mg/L玉米素或25mg/L水杨酸处理5d后雨生红球藻虾青素积累最多。该浓度玉米素或水杨酸可显著提高光胁迫下藻细胞密度,最高分别达到3.4×10~5cell/mL和3.0×10~5cell/mL;同时玉米素与水杨酸组中虾青素含量显著上升,分别为1.7%和1.6%,比对照组分别增加29.2%和25.6%。玉米素缓解了高光逆境条件下光合作用基因——Rubisco大亚基(rbcL)及其活化酶(rca)、碳酸酐酶(ca)的下调表达,但对虾青素合成途径β-胡萝卜素酮化酶基因(bkt)的表达量没有显著影响;而水杨酸则相反,在胁迫后期不能缓解光合作用相关基因的下调表达,但可使bkt基因显著上调,最高可达对照组的2.5倍。本研究首次比较了玉米素和水杨酸对雨生红球藻生长和虾青素积累的影响,发现玉米素比水杨酸具有更好的促进雨生红球藻中虾青素积累的效果。
