Abstract
Euglena sanguinea is known to produce the alkaloid toxin euglenophycin and is known to cause fish kills and inhibit mammalian tissue and microalgal culture growth. An analysis of over 30 species of euglenoids for accumulation of euglenophycin identified six additional species producing the toxin; and six of the seven E. sanguinea strains produced the toxin. A phylogenetic assessment of these species confirmed most taxa were in the Euglenaceae, whereas synthesis capability apparently has been lost in the Phacus, Eutreptiella, and Discoplastis branches.
摘要
血绿眼虫(Euglena sanguinea)已知会产生生物碱毒素血绿蝇素，并会导致鱼类死亡和抑制哺乳动物组织及微藻培养生长。对超过 30 种眼虫的分析发现，有 6 种额外的物种会产生这种毒素；而在 7 株血绿眼虫(E. sanguinea)中，有 6 株会产生这种毒素。对这些物种的系统发育评估证实，大多数分类群属于眼虫科(Euglenaceae)，而在 Phacus、Eutreptiella 和 Discoplastis 分支中，这种合成能力显然已经丧失。
