The possible involvement of calcium in the regulation of methyl jasmonate-promoted senescence of detached rice (Oryza sativa) leaves was investigated. Calcium effectively reduced methyl jasmonate-promoted senescence of detached rice leaves. The effect of methyl jasmonate on the senescence was also significantly reduced by calcium ionophore A23187. Methyl jasmonate-promoted senescence of detached rice leaves may be mediated through blocking the entrance of calcium ions into the cytosol.
钙可能参与调控茉莉酸甲酯诱导的离体水稻叶片衰老。钙能有效抑制茉莉酸甲酯诱导的离体水稻叶片衰老,钙载体 A23187 也能显著降低茉莉酸甲酯对叶片衰老的影响。茉莉酸甲酯诱导的离体水稻叶片衰老可能是通过阻止钙离子进入细胞质来实现的。
