Ca2+是植物在不同发育阶段和响应多种复杂环境刺激的核心调控因子。CBL蛋白(Calcineurin B-likeproteins)和CIPK蛋白激酶(CBL-interacting protein kinases)通过相互作用解码特异的钙信号从而实现相应的生理功能。文章主要从CBL-CIPK信号系统关键组分及相互作用,解码钙信号的机制,生理功能和调节机制等方面综述相关研究进展,并对未来的研究方向进行展望。
In this study,an efficient regeneration system of Broussonetia papyrifera was established.Using leaf disks and petiole fragments as explants,MS media supplemented with different concentrations of BA and NAA were investigated for shoot induction.Then regenerated shoots were transferred to MS medium containing 0～0.6 mg·L-1 NAA to induce roots.A BA/NAA combination of 2.5/0.1(mg·L-1) produced the highest percentage of regeneration with petiole explants and of 1.5/ 0.05(mg·L-1) with leaf explants.The optimal medium for rooting was MS medium supplemented with 0.05 mg·L-1 NAA.
