Laminarin regulates mitogen-activated protein kinase (CsMAPK) and CsWRKY3. Mean transcript levels (+SE, n = 5) of CsMAPK (a) and CsWRKY3 (b) in leaves of tea plants treated with laminarin at a concentration of 200 mg L⁻¹ (Lam), relative to controls (Con). (c) Western blot analysis of the accumulation of CsMAPK and CsWRKY3. The grouping of blots was cropped from different parts of the same gel. Asterisks indicate significant differences in transcript levels between treatments and controls at each time point (*P < 0.05; **P < 0.01; Student’s t-test).
