Photosymbiosis is a widespread form of mutualistic symbiosis found among many metazoan lineages (Melo Clavijo et al., 2018) and is particularly beneficial for the animal host. The assimilates translocated by the symbionts to the host can meet or even supersede the host's nutritional demands, and this is particularly important for reef-building corals (Stanley & Lipps, 2011). A rather unusual form of photosymbiosis is found among some sacoglossan sea slugs (Trench, 1975; Rumpho, Summer & Manhart, 2000) and in two rhabdocoel flatworms (Van Steenkiste et al., 2019). In these taxa, only chloroplasts, ingested from algal prey, occur intracellularly as some sort of...

在含有质体的海蛞蝓 Elysia viridis 的进食过程中，Kleptoplasts 不断被消化

光共生是在许多后生动物谱系中发现的一种普遍的互惠共生形式。Melo Clavijo等人。, 2018) 并且对动物宿主特别有益。共生体转移到宿主的同化物可以满足甚至取代宿主的营养需求，这对造礁珊瑚尤为重要。斯坦利和利普斯，2011 年）。在一些 sacoglossan 海蛞蝓中发现了一种相当不寻常的光共生形式。海沟，1975 年； Rumpho, Summer & Manhart, 2000) 和两个弹状体扁虫 (Van Steenkiste等人。, 2019)。在这些分类群中，只有从藻类猎物摄取的叶绿体在细胞内作为某种...
