Absence of correlation between oil and starch content in various Chlamydomonas reinhardtii strains. C2,3,6,7,8,9,16,18,20 are independent lines of complementants for sta6 (BafJ5). Mean contents in starch and oil were calculated based on at least three independent experiments. Error bars indicate standard deviations. Mean content in oil and starch were subjected to a Kendall rank correlation test. The null hypothesis that oil and starch are independent cannot be rejected (tau statistics = 0.07; two-tailed p = 0.673; n = 20).
