| Abstract: | Previous studies on kleptoplasty in sacoglossans have used different methodology to investigate how long the sacoglossans
are able to keep photosynthetically active (functional) chloroplasts. In this study we have used Pulse Amplitude Modulated
Fluorometry to measure the quantum yield of charge separation in photosystem II in dark acclimated cells (ΦIIe) to detect the status of photosynthetic activity. Seven species of sacoglossa, Plakobranchus ocellatus, Elysia timida, Elysia sp, Elysia tomentosa, Thuridilla carlsoni, T. lineolata and Elysiella pusilla, were investigated regarding their ability to retain functional chloroplasts (RFC). The results show three different levels
of RFC’s where P. ocellatus has the longest RFC for more than 11 months, E. timida with a RFC 1/4 than P. ocellatus (almost 3 months) and the rest with RFC’s down to 1/22 of P. ocellatus (up to 15 days). Based on these results, and compared to previous studies, eight different levels of retention abilities
of non-functional and functional chloroplasts in sacoglossans are proposed. As far as we know, this is a novel method studying
chloroplast functionality in sacoglossans. |
