Expanded diversity of pedinophytes provides a window into the evolution of the genetic code in organelles.

ABSTRACT: Mitochondria and plastids of various lineages exhibit genetic code alterations. However, the knowledge of the diversity and occurrence, mechanistic underpinnings, and evolutionary origins of codon reassignments in organelles remains incomplete. To address this gap, we focused on organelles of the neglected green algal class Pedinophyceae, as well as pedinophyte-derived secondary plastids of green-coloured dinoflagellates (peDinoflagellates). We isolated and characterized a novel pedinophyte, herein formally described as Oistococcus okinawensis gen. et sp. nov., and phenotypically documented the previously sequenced but morphologically uncharacterized strain YPF-701, herein described as Akinorimonas japonica gen. et sp. nov. Based on phylogenetic analyses, both new taxa were classified into
