Chlorella sp. FC2 IITG temporal nitrogen-starvation LC-MSMS


ABSTRACT: Proteomics study in non-model alga Chlorella FC2 IITG (FC2) challenged with nitrogen starvation for 120 h. Three different nitrogen starvation time-points 40 h, 88 h and 120 h was compared with 0 h (nitrogen sufficient condition). Comparative proteomics analysis was performed using 4-plex isobaric tags for relative and absolute quantification (iTRAQ) labelling strategy, followed by chromatographic separation and final generation of tandem mass spectrometry (MS/MS) spectra of tryptic digested peptides on Q-TOF mass spectrometer.

To understand the post-transcriptional molecular mechanisms attributing to oleaginousness in microalgae challenged with nitrogen starvation (N-starvation), the longitudinal proteome dynamics of Chlorella sp. FC2 IITG was investigated using multipronged quantitative proteomics and multiple reaction monitoring assays. Physiological data suggested a remarkably enhanced lipid accumulation with concomitant reduction in carbon flux towards carbohydrate, protein and chlorophyll biosynthesis. The proteo  ...[more]
