Transcript abundance of chrysanthemum CmNF-YB8. a Transcript abundance of CmNF-YB8 in different organs. Plants at 5 days after transplanting and growth under long day (LD) conditions were used. Apical buds (AB), leaves (L), stems (St), and roots (R) were harvested. b Transcript abundance of CmNF-YB8 in apical buds and leaves of differently aged chrysanthemum. Plants were grown under LD conditions. Samples were harvested every 10 days from 5 days after propagation. c Transcript abundance of CmNF-YB8 in chrysanthemum grown under different day lengths conditions, including LD and SD, under a low-temperature (4 °C) regime, or following treatment with gibberellic acid (GA_4/7). Leaves were harvested 30 days after each treatment. qRT-PCR was performed to evaluate expression of CmNF-YB8, using UBIQUITIN as the control. Three independent experiments were performed and error bars indicate standard deviation. Significant differences were determined using Duncan’s multiple range test (P < 0.05)
