The mitochondrial genome was composed of 38,696 bases and contained 64 genes, including 31 protein-coding genes (CDS), 2 ribosomal RNA (rRNA) genes and 23 transfer RNA (tRNA) genes. For the chloroplast, the genome was composed of 130,200 bases with 169 genes (131 CDS, 6 rRNA genes, 31 tRNA genes, and 1 transfer messenger RNA gene). Phylogenetic trees, using the maximum-likehood method and partial genes currently available for Haslea ostrearia and other diatom species, suggested the proximity of all the Haslea ostrearia strains/isolates and the possibility of using these genomes as future references. specialized FRANCE 076AMEPLA04 8 10 1092-1096 2023 2380-2359 https://www.documentation.ird.fr/hor/fdi:010090477 10.1080/23802359.2023.2268747 2380-2359 [F B010090477] https://www.documentation.ird.fr/hor/fdi:010090477 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2023-11/010090477.pdf IRD - Base Horizon / Pleins textes 2023-10-16 2025-02-25 fdi:010090477 fre
