Fig. 2.

The flowering times of C. australis on different hosts under different photoperiod conditions. (A) The flowering times of day-neutral wild tomato, tobacco (cv Samsun), and cucumber hostplants and their respective parasitizing dodder cultivated under intermediate photoperiod (IP) (n = 21, 21, 20, 20, 21, and 21; from Left to Right). (B) The flowering times of soybean Dongsheng 1 (D1) and Williams 82 (W82) and their parasitizing dodder under LD and SD conditions (n = 40, 40, 30, and 26 under LD and n = 26, 23, 20, and 18 under SD; from Left to Right). (C) The flowering times of WT soybean (W82) and transgenic soybean overexpressing GmFT2a (35S:GmFT2a) and their respective parasitizing dodder, under LD conditions (n = 27, 27, 27, and 27; from Left to Right). (D) The flowering times of WT tobacco (K326) and NtFT5-knockout mutants and their parasitizing dodder (n = 12, 12, 16, and 16; from Left to Right). NF, no flowering until 180 d. Each panel indicates the data from the same group of host–dodder interaction partners. The horizontal bars within boxes indicate medians. The tops and bottoms of boxes indicate upper and lower quartiles, respectively. The upper and lower whiskers represent maximum and minimum, respectively. R² indicates correlation coefficients, which were obtained from correlation analyses using the flowering times of each pair of host–dodder interaction partners.
