- Chrysanthemum MAF2 regulates flowering by repressing gibberellin biosynthesis in response to low temperature

Effects of GA treatments on chrysanthemum flowering under LD conditions. (a) GA content in the shoot tips of plants at LT5 and at LT5 + N2. Plants grown for 5 or 7 weeks under normal temperature and LD conditions were used as controls (C5 and C7). (b) The effects of exogenous GA4/7 treatment and 5‐week low‐temperature treatment (LT5) on plant height of 8‐week‐old chrysanthemum. GA was given twice per week for 2 months. (c) The effects of exogenous GA4/7 treatments and 5‐week low‐temperature treatments (LT5) on initial flower bud appearance in control and treated plants. (d) Phenotypes of control and treated plants were observed after 14 weeks. The results are the means of three biological replicates with standard deviations. Asterisks indicate statistically significant differences (Student's t‐test, **P < 0.01). Different letters indicate significant differences according to Duncan's multiple range test (P < 0.05). Scale bars, 5 cm.

Effects of GA treatments on chrysanthemum flowering under LD conditions. (a) GA content in the shoot tips of plants at LT5 and at LT5 + N2. Plants grown for 5 or 7 weeks under normal temperature and LD conditions were used as controls (C5 and C7). (b) The effects of exogenous GA4/7 treatment and 5‐week low‐temperature treatment (LT5) on plant height of 8‐week‐old chrysanthemum. GA was given twice per week for 2 months. (c) The effects of exogenous GA4/7 treatments and 5‐week low‐temperature treatments (LT5) on initial flower bud appearance in control and treated plants. (d) Phenotypes of control and treated plants were observed after 14 weeks. The results are the means of three biological replicates with standard deviations. Asterisks indicate statistically significant differences (Student's t‐test, **P < 0.01). Different letters indicate significant differences according to Duncan's multiple range test (P < 0.05). Scale bars, 5 cm.
