Fig. 4From: Delineating the molecular responses of a halotolerant microalga using integrated omics approach to identify genetic engineering targets for enhanced TAG productiona Cumulative 1D 1H NMR spectra (n = 6) of Scenedesmus sp. IITRIND2 Control polar extracts (pink) stacked up with that of ASW cultures (blue). The spectral peaks were assigned for particular small-molecule metabolites. The water region at δ 4.6–4.9 was removed for clarity. The abbreviations used are: 3-OH-IV: 3-hydroxyisovalerate; Gln: glutamine; Glu: glutamate; EA: ethanolamine; Cys: cysteine; Cho: choline; PC: phosphocholine; GPC: glycerophosphocholine; DSS: 4,4-dimethyl-4-silapentane-1-sulfonic acid; TMAO: trimethylamine-N-oxide; DMG: N,N-dimethylglycine; Phe: phenylalanine; ATP: adenosine triphosphate; UDP glucose: uridine diphosphate glucose. b Combined PCA 2D score plot resulted from the analysis of 1D 1H CPMG spectra of Scenedesmus sp. IITRIND2 cultivated in control and ASW medium (green = control; red = salt). The semi-transparent red and green ovals represent the 95% confidence interval. c PCA loadings plot revealing the metabolites of responsible for the discrimination pattern, the more the metabolite is away from the origin (0,0) more it contributes in the group discriminationBack to article page
