| 中文摘要 | Chemically hydrolyzed curdlan oligosaccharides (CRDO), low degree of polymerization (DP) of β-1,3-glucan, were prepared to compare with Laminaran (Lam) with high DP for discussing the difference on defense-inducing activity in tobacco. Fast response defenses such as extracellular pH shift, H2O2 production, nitric oxide （NO） release and stomatal movement under light as well as the protection against tobacco mosaic virus (TMV) were performed. CRDO triggered faster extracellular alkalinization than Lam. Refractory states analysis showed there existed different perception modes between β-1,3-glucan and chitosan oligosaccharides (COS). Elicitors induced cells to generate NO probably via nitric oxide synthase (NOS) pathway. Moreover, CRDO exhibited more intensive than Lam in stomatal movement. However, protection against TMV implied Lam played a longer term role than CRDO in defense responses. Therefore, we concluded β-1,3-glucan with low DP played a vital role in rapid responses, whereas high DP β-1,3-glucan displayed durable effects. |
