The table shows the average of all the observations from 4 repeated tests, in the form of mean ± standard error of representation, wild-type C. reinhardtii CC-849 represents a control, TFA represents the total fatty acid content. All data are expressed in mg/g (dry weight)

The data represent the means ± SD of three replicate experiments and were analyzed by Student’s t-test (n = 3)

^aP <0.05; ^bP <0.01. aRP1.1, aRP1.2, aRP1.3, aRP1.4 is transformed amicroRNA-PEPC1 into C. reinhardtii; aRP2.1, aRP2.2, aRP2.3 is transformed amicroRNA-PEPC2 into C. reinhardtii
