Figure 4.
Profile of lipid species identified in Azospirillum-inoculated and non-inoculated samples harvested at 7, 14, and 21 DAI using K-means clustering. Clusters formed in the two treatments were paired based on their lipid species composition (a–f). At each time point, biological replicates are displayed as lines of dots, where each dot represents a lipid species. The main lipid classes of each cluster couple are also displayed. Shade of the fitting line represents the standard deviation within metabolite groups. ADGGA: acyl diacylglyceryl glucuronide, Cer-AP: ceramide alpha-hydroxy fatty acid-phytospingosine, DG: diacylglycerol, DGDG: digalactosyldiacylglycerol, DGGA: diacylglyceryl glucuronide, GP: glycerophospholipids, HexCer-AP: hexosylceramide alpha-hydroxy fatty acid-phytospingosine, TG: triacylglycerol.
