囊舌海蛞蝓的功能性kleptoplasty是已知的最奇怪的光合作用协会之一。这些海洋软体动物，Elysia viridis的成员之一，是已知的，将质体从各种不同的藻类食物来源，但显然不同的结果和差异的时间跨度的保留功能kleptoplasts。虽然以前表明，茎从松藻的kleptoplasts保持功能几个星期（长期保留，LtR），那些茎从Bryopsis hypnoidesor Cladophora rupestris被认为是有限的使用光合能力（短期保留，StR）。这很重要，因为它触及了一个流行但有争议的问题，即光合作用对这些鼻涕虫的繁荣有多重要。本研究的目的是确定在何种程度上的质体来源决定保留时间。所以，我们比较一下。以刚毛藻为食。珠催眠药结果表明，B. hyponidesemulate 14CO2，但在整个饥饿的第一周迅速下降的效率，而刚毛藻质体。令人惊讶的是，开始并没有被结合。不同样品的齿舌表现出对食物源的适应性，当摄食刚毛藻时，E. Viridis在实验室条件下在饥饿和非饥饿条件下存活。我们的结果表明：（i）E.不同的食物来源不同。hypnoides和刚毛藻属Cladophorasp，和（ii）光合活性的窃虫体不是生存的必然要求。
Functional kleptoplasty in sacoglossan sea slugs is among the most curious photosynthetic associations known. One member of these marine molluscs,Elysia viridis, is known to incorporate plastids from a variety of different algae food sources, but with apparently different outcomes and differences in the time span of the retention of functional kleptoplasts. While it was previously shown that kleptoplasts that stem fromCodium tomentosumare kept functional for several weeks (long-term retention, LtR), those that stem fromBryopsis hypnoidesorCladophora rupestrisare thought to be of limited use regarding photosynthetic capacity (short-term retention, StR). This is important, because it touches upon the popular yet controversial question of how important photosynthesis is for the thriving of these slugs. The aim of the present study was to determine to what degree the plastid source determines retention time. We, therefore, comparedE. viridisfeeding on eitherCladophorasp. orB. hypnoides. We show that kleptoplasts ofB. hypnoidesincorporate14CO2, but with rapidly declining efficiency throughout the first week of starvation, while the plastids ofCladophorasp. are, surprisingly, not incorporated to begin with. The radulae of the different samples showed adjustment to the food source, and when feeding onCladophorasp.,E. viridissurvived under laboratory conditions under both starvation and non-starvation conditions. Our results demonstrate that (i) the ability to incorporate plastids byE. viridisdiffers between the food sourcesB. hypnoidesandCladophorasp., and (ii) photosynthetic active kleptoplasts are not an inevitable requirement for survival.
