Table 2 Transcription factors involved in stresses

From: Microalgae for the production of lipid and carotenoids: a review with focus on stress regulation and adaptation

Species Transcription factors Stresses Performances References
Chlamydomonas reinhardtii PHR1 Phosphate starvation PHR1 acts downstream in the phosphate starvation signaling pathway via binding the promoter of phosphate starvation responsive structural genes [83]
Chlamydomonas reinhardtii LCR1 CO2-limiting stress LCR1 transmits the low CO2 signal to at least three CO2-responsive genes and then fully induces carbon-concentrating mechanism [94]
Dunaliella bardawil WRKY Salt stress All the carotenogenic genes can be recognized by WRKY transcription factors [95]
Chlamydomonas NRR1 Nitrogen starvation NRR1, a putative SQUAMOSA promoter binding protein-type transcription factor, was proved to be a regulator of N-induced TAG biosynthesis [86]
Chlamydomonas reinhardtii PSR1 Nitrogen starvation PSR1 is a pivotal switch that triggers cytosolic lipid accumulation [93]
Chlamydomonas reinhardtii PSR1 Phosphorus starvation PSR1 gene is an important determinant of lipid and starch accumulation in response to phosphorus starvation but not nitrogen starvation [92]
Chlorella ellipsoidea GmDof4 Nitrogen starvation Increase of lipid content without growth limitation [90]
Nannochloropsis salina NsbHLH2 Nitrogen limitation Biomass and FAME productivity was increased by 36% and 33%, respectively [99]
Nannochloropsis gaditana ZnCys Nitrogen starvation Lipid is doubled by attenuation of ZnCys expression [100]
