OsERF48 overexpressing lines have vigorous root growth. (a–c) Comparison of 6‐day‐old seedlings roots of OsERF48 overexpression and nontransgenic (NT) plants. (a) Root morphology of plants grown on normal growth media. (b) Root growth of plants grown on a 40% polyethylene glycol (PEG)‐infused media for in vitro drought conditions. (c) Lateral root morphology of plants grown on normal growth media (scale bar, 1 mm). (d) Lateral root morphology of RNAi Os ERF 48 and NT plants (scale bar, 2 mm). (e) Lateral root density of RNAi Os ERF 48 and NT plants. (f) Primary root length of the OsERF48 overexpressing and NT plants grown on the PEG‐infused media. (g) Lateral root density of the OsERF48 overexpressing and NT plants grown on the PEG‐infused media. Lateral root density was measured within a 3‐ to 4.5‐cm region from the root tip. Each data point represents the mean ±  SD (n = 15 plants per independent lines of each genotypes). A single (*P < 0.05) and two asterisks (**P < 0.01) represent significant differences, as determined by the student's t‐test between the transgenic and NT plants. PR, primary root; LR, lateral root; ROX,ROXO s ERF 48; OX,OXO s ERF 48; RNAi,RNAi Os ERF 48.
