Glycerol Biosynthesis Pathways from Starch Endow <i>Dunaliella salina</i> with the Adaptability to Osmotic and Oxidative Effects Caused by Salinity.

ABSTRACT: Dunaliella salina, a unicellular and eukaryotic alga, has been found to be one of the most salt-tolerant eukaryotes with a wide range of practical applications. To elucidate the underlying molecular mechanisms of D. salina in response to salinity stress, we performed transcriptome sequencing on samples under different stress conditions. A total of 82,333 unigenes were generated, 4720, 1111 and 2611 differentially expressed genes (DEGs) were identified under high salt stress, oxidative stress and hypertonic stress, respectively. Our analysis revealed that D. salina responds to salinity stress through a complex network of molecular mechanisms. Under high salt stress, starch degradation is regulated by AMY (α-amylase) and PYG (glycogen phosphorylase) with alternative expr
