Integration of proteome and transcriptome refines key molecular processes underlying oil production in Nannochloropsis oceanica

Abstract

This study adds a proteome perspective on the major pathways for TAG accumulation in <i>Nannochloropsis</i> spp. Temporal changes of proteome exhibited distinct adaptation phases that are usually delayed relative to transcriptomic responses. Notably, proteome data revealed that photosynthesis and carbon fixation are still ongoing even after 48 h of N-. Moreover, sometimes completely opposite trends in proteome and transcriptome demonstrate the relevance of underexplored post-transcriptional regulation for N- adaptation.
