Candidate genes involved in carbon fixation in Eutreptiella sp. compared with other potential C4 algae Thalassiosira pseudonana (T.ps) and Ostreococcus tauri (O.ta).

The numbers for Eutreptiella represents the number of unique sequences found in our dataset. The numbers of genes in other organisms are based on genome annotations. Sequences and annotation results are listed in Table S15.– Genes were not found in our dataset. This might be due to insufficient sequencing depth.aGenes potentially involved in C4 carbon fixation.bObtained from cloning instead of transcriptome.cData adapted from Derelle et al.[63].
