一些sacoglossan海蛞蝓从它们的食物中隔离功能性质体（kleptoplasts），这些质体继续以光依赖的方式在动物体内固定CO2。在植物和藻类中，质体和线粒体代谢的联系方式超出了通过光合作用提供富含能量的碳化合物的范围，但蛞蝓线粒体如何应对饥饿或质体生物化学的改变尚未被探索。我们从RNA-Seq数据中组装了质体隔离海蛞蝓Elysia timida和Elysia cornigera的线粒体基因组，并通过引物步移与线粒体DNA的标准测序进行了补充。我们的数据证实了两个Sacoglossa的姐妹种的关系，并从饥饿过程中的代谢相关的代谢变化的分析，我们推测，kleptoplasts可能有助于重新路由或回收的还原力独立，但可能改善，光合作用。
Some sacoglossan sea slugs sequester functional plastids (kleptoplasts) from their food, which continue to fix CO2 in a light dependent manner inside the animals. In plants and algae, plastid and mitochondrial metabolism are linked in ways that reach beyond the provision of energy-rich carbon compounds through photosynthesis, but how slug mitochondria respond to starvation or alterations in plastid biochemistry has not been explored. We assembled the mitochondrial genomes of the plastid-sequestering sea slugs Elysia timida and Elysia cornigera from RNA-Seq data that was complemented with standard sequencing of mitochondrial DNA through primer walking. Our data confirm the sister species relationship of the two Sacoglossa and from the analysis of changes in mitochondrial-associated metabolism during starvation we speculate that kleptoplasts might aid in the rerouting or recycling of reducing power independent of, yet maybe improved by, photosynthesis.
