CpGLP1 protein–pectin interaction assays. ELISA plate wells were coated with solutions supplemented with pectin from citrus peel (P9135; Sigma-Aldrich, Saint Luis, MO, USA) and from C. plantagineum untreated leaves or without pectin. After coating and blocking the wells, wells were incubated with 0.2 µg of purified recombinant CpGLP1 protein. The bound CpGLP1 proteins were detected with His-tag antibodies. Mean absorbance values were calculated from three technical and three biological repetitions (mean ± SEM). Asterisks above bars denote statistically significant differences compared to control (− pectin) samples (t-test, **P < 0.01, ***P < 0.001)
