1. Shoot biomass (fresh weight, FW), primary root elongation (PRE), lateral root density (LRD) and total lateral root length (TLRL) of 7-d (PRE) or 14-d (FW, LRD, TLRL) old seedlings from the wild type (Col-0) or ScTPO1- and ScPDR5-expressing lines grown in control medium. Values represent means ± SD (n = 8), with similar results being obtained in three independent experiments performed with different seed batches. Numbers in parentheses indicate the P value (comparison with the wild type) obtained by Student’s t-test.
