Abstract: BackgroundSolar-powered sea slugs are famed for their ability to survive starvation due to incorporated algal chloroplasts. It is well established that algal-derived carbon can be traced in numerous slug-derived compounds, showing that slugs utilize the photosynthates produced by incorporated plastids. Recently, a new hypothesis suggests that the photosynthates produced are not continuously made available to the slug. Instead, at least some of the plastid’s photosynthetic products are stored in the plastid its… Show more

“…It is still unknown how much the kleptoplasts might actually contribute to the host metabolism-data from CO 2 fixation experiments range from 1% (Rauch et al, 2017) to 60% (Raven et al, 2001)-and thus if the kleptoplasts can compensate for the lack of nutrition. Further, how photosynthates are made accessible to the slugs is unknown, but at present it seems that they are only made accessible for the slugs upon digestion (Laetz et al, 2016(Laetz et al, , 2017). It appears that the transcriptional response from the slugs to starvation is less dependent on the photosynthetic activity of the kleptoplasts, but rather to the starvation itself .…”

“…The motive behind kleptoplasty in sacoglossan sea slugs remains elusive and the importance of on-going photosynthesis and CO 2 fixation is under debate ( Christa, Zimorski, et al 2014 ; Pierce et al 2015 ; de Vries et al 2015 ; Laetz et al 2017 ). It remains uncertain to what degree CO 2 fixation contributes to the overall energy budget of the slugs and alternative reasons are rarely considered (Christa, de Vries, et al 2014 ; de Vries et al 2014 ).…”
