The solid relationship of the plastidial ACCase between the SAR species and the Prasinophyceae can thus be described by horizontal gene transfer from an unknown organism, which could both be a Prasinophyte or an unsequenced alga associated to the Prasinophyceae
The close romance in between plastidial ACCases from SAR, Cryptophyta and Prasinophyceae shown in this article can either be described by horizontal or endosymbiotic gene transfer, while gene duplication can…
