The discovery that Trichomonas vaginalis, an early diverging protist that lacks mitochondria but has energy-producing hydrogenosomes, makes bacterial-like heat shock proteins suggests that symbionts ancestral to mitochondria and hydrogenosomes were present at early stages of eukaryote evolution.
阴道毛滴虫是一种早期分化的原生生物，它没有线粒体，但具有能产生能量的氢化酶体，其能产生类似细菌的热休克蛋白这一发现表明，线粒体和氢化酶体的共生祖先在真核生物进化的早期阶段就已存在。
