CmANR1 promotes adventitious root (AR) and hair root development in chrysanthemum. a Relative expression of CmANR1 in three CmANR1-overexpressing (OVXs) and wild-type (WT) chrysanthemum lines. b Phenotype of CmANR1-overexpressing (OVXs) and WT chrysanthemum (10 days-old, in vitro tissue cultures). Scale bar = 1 cm. c, d AR number (c) and AR length (d) of CmANR1-OVXs and WT chrysanthemum. e Phenotype of root hair on CmANR1-OVXs and WT chrysanthemum. Scale bar = 40 μm. f, g Root hair density (f) and length (g) of CmANR1-OVXs and WT chrysanthemum. Statistical significance was determined using Student’s t-test. No significance (n.s.): p > 0.01; *p < 0.01; **p < 0.001
