Expression analysis of PvCO1 and PvCO2. a Daily high and low temperatures and daylength in lin’an (China). b, c Tissue-specific expression of PvCO1 and PvCO2 in Ph. violascens. The different tissues were collected from 5 pm to 6 pm on April 13 (LD 13:11 h). The maximum and minimum temperatures on April 13 were 17.3 °C and 13.9 °C, respectively. d, e Temporal expression of PvCO1 and PvCO2 in Ph. violascens. The three plants for samples flowered for the second time. The flower bud of these three plants displayed between on March 12 and 22, and they died between on May 21 and May 31. The period between black solid lines represents flowring time. f, g Daily expression of PvCO1 and PvCO2 in Ph. violascens. Dusk and dawn are at 17:00 and 5:30.Expression of the Actin gene was used as an internal control. Gray areas indicate darkness. Gray shading denotes the dark/night portion of 24 h cycle. Error bar indicates standard deviation. Y axis, relative transcript level of PvCO1 or PvCO2 compared with that of PvActin. A, B indicate highly significant differences
