Growth inhibition of P. patens wild type by caffeic acid (CA). (A) Diameter of plants grown on solid culture medium supplemented with different concentrations of CA measured after 4 weeks of cultivation (n = 10, bars represent standard deviation). (B) Growth with 500 µM CA (right) and without CA (left) measured after 4 weeks. (C) Optical online monitoring of arial plant growth displaying the relative area increase of a moss plant cultivated with 500 µM CA and without CA (this figure is available in colour at JXB online).
