Screening and phenotype analysis of CrFAX1 and CrFAX2 overexpression transformants. a The expression levels of crfax1 and crfax2 in both CrFAX1 and CrFAX2 transformants (CrFAX1-OX and CrFAX2-OX), respectively, were detected by qRT-PCR assays. b The growth rates of the normal strain (WT) and the two CrFAXs transformants were measured according to the cell numbers. The total intracellular lipids c and chlorophyll a contents d of the normal strain and two CrFAXs transformants were detected. The results are shown as the mean expression ± standard deviation (SD) of three independent experiments. Student’s t test, *P < 0.05, **P < 0.01
