520 |a Diatoms are unicellular algae with a set of extraordinary genes, metabolic pathways, and physiological functions acquired by secondary endosymbiosis, especially for their efficient photosynthetic carbon fixation mechanisms, which can be a reason for their successful environmental adaptation and great contribution to primary production. Based on the available genomic information, the expression patterns of carbon fixation genes were analyzed using transcriptomic sequencing and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) in Skeletonema marinoi. Meanwhile, suitable reference genes applying to specific experimental treatments were selected. In our results, carbon fixation genes were standardized by actin and TATA box-binding protein-coding genes in growth phase samples and stress conditions, respectively. It was found that a series of carbon fixation genes, such as the pyruvate orthophosphate dikinase (PPDK)-coding gene, had significantly up-regulated expression in nitrogen-starvation, phosphate-starvation, and low-temperature conditions, but consistently down-regulated in silicate-starvation treatment. These carbon fixation genes exhibited variable expression levels in different conditions and will be useful for investigating gene expression mechanisms in S. marinoi and improve our understanding of diatom carbon fixation pathways
