From: Astaxanthin accumulation difference between non-motile cells and akinetes of Haematococcus pluvialis was affected by pyruvate metabolism

Fig. 4

The metabolism network and transcription regulation of astaxanthin metabolism. Deep red, dark blue and bright yellow background represent astaxanthin metabolism pathway, pyruvate metabolism pathway and lutein metabolism pathway, respectively. Solid arrows indicate that the reaction proceeds continuously, dotted arrows indicate that intermediate metabolites are omitted. 1235 and 1246 represent Sample 1, Sample 2, Sample 3 and Sample 5 of control group (1235 route) and Sample 1, Sample 2, Sample 4 and Sample 6 of treatment group (1246 route), respectively. Sample 1, Sample 2 and Sample 3 were the heterotrophic cells at 100 h, 250 h, and 550 h, respectively; Sample 4 was Sample 2 cells induction for 0.5 day; Sample 5 was Sample 3 cells induction for 6 days; Sample 6 was the Sample 2 cells induction for 6 days. The number of replications is two (n =2)
