Fig. 4. Quantification of strigolactones and expression of strigolactone biosynthesis genes in roots of WT and RNAi lines without mycorrhization.

Fig. 4

Germination of Orobanche cumana Wallr. a and Orobanche aegyptiaca Pers. b seeds in response to a range of concentrations of root exudates of WT and RNAi lines. Sterile water (C) and 1 mg L-1 synthetic strigolactone (GR24) were used as negative and positive controls. c Expression of strigolactone biosynthetic genes and MdNSP1 in WT and RNAi lines under NM conditions. NM=nonmycorrhizal. Data are expressed as means ± SDs (n = 4 for c, n = 12 for a and b). Data with different letters and asterisks differ significantly (P < 0.05), as determined by one-way ANOVA and Tukey’s test
