Schematic diagram of carotenoid and fatty acid metabolism in D. salina Y6. The dotted and solid lines represent indirect and direct chemical reactions, respectively; red triangles, green squares, and black ellipses represent related compounds are increased under the high light (HL), high salt (HS), and nitrogen-depleted (ND) conditions, respectively; G3-P, glyceraldehyde-3-phosphate; PEP, phosphoenolpyruvate; MVA Pathway, mevalonic acid, produced in the mevalonate pathway; MEP pathway, methylerythritol 4-phosphate pathway; IPP, isopentenyl pyrophosphate; GGPP, geranylgeranyl pyrophosphate
