Amphidinium is a genus of dinoflagellates. The type for the genus is Amphidinium operculatum Claparède & Lachmann. The genus includes the species Amphidinium carterae which is used as a model organism.[1]
As dinoflagellates, Amphidinium spp. have chloroplasts. The Amphidinium chloroplast genome is unusual in not having a single contiguous circular genome [2][3]. Instead, chloroplast genes encoded in chloroplast DNA are found on numerous 2-3 kbp minicircles [2][3], analogous to plasmids. Most minicircles have only a few protein-coding genes; many have just a single gene [2][3]. There are reports of minicircles that do not have known transcripts, like in the Amphidinium carterae chloroplast genome [3], although these were not found in the Symbiodinium sp. Clade C3 chloroplast genome [2]. Minicircle-derived transcripts can be processed in ways not typical of eukaryotes, including the addition of a 3' poly(U) tail [3], as opposed to the typical poly(A) tail derived from polyadenylation of eukaryotic transcripts. Minicircle-derived antisense transcripts are also produced, but without 3' poly(U) tails [3].
