Physical properties of wild type and xi1 xi2 xik inflorescence stems. (A) Growth rates of inflorescence stems during 10-h gravitropism. Error bars represent SD, n = 9; p < 0.05 (Student’s t-test). (B) Tendency for stems to bend in gravisensitive region according to flexure test. Higher flexural modulus of triple mutant shows greater stiffness of the stem. (C) Diameters of the same stems assayed in flexure test. Error bars represent SD, n = 35–45; p < 0.05; ∗∗p < 0.01 (Student’s t-test).
