The competitive effect existing in Caro-13 and Caro-9 strains. A A significant difference in the production of β-carotene in both strains. B The growth curves of both strains. C The relative transcriptional levels of the exogenous genes in the Caro-9 strain after 16 h growth. D The relative transcriptional levels of the exogenous genes in the Caro-13 strain after 16 h growth. The ACT1 gene was used as the reference gene. Error bars indicate the SD for samples tested in triplicate
