Transcriptome Analysis of the Accumulation of Astaxanthin in Haematococcus pluvialis Treated with White and Blue Lights as well as Salicylic Acid

Figure 13

Expression patterns of four genes (i.e., bkt, crtZ, lyc, and psy) involved in the synthesis of astaxanthin in Haematococcus pluvialis treated with white light, blue light, and blue light with salicylic acid (SA). IPI: isopentenyl diphosphate isomerase; PSY: phytoene synthase; ZDS: zeta-carotene desaturase; PDS: phytoene desaturase; LYC: lycopene cyclase; CrtZ: β-carotene hydroxylase; BKT: β-carotene ketolase.
