具有改变的生长特性的植物及其制备方法
摘要：
本发明涉及通过调节植物中B型CDK核酸的表达，和/或通过调节植物中B型CDK蛋白的活性和/或水平来改变植物生长特性的方法。本发明也涉及具有改变的生长特性的转基因植物，该植物相对于对应的野生型的植物中的表达、活性和/或水平，具有调节的植物中B型CDK核酸的表达，和/或调节的B型CDK蛋白的活性和/或水平。本发明还提供了新的筛选方法，鉴定相对于对应的未突变CDK具有提高了CDK活性的CDK突变体。本发明同时提供了新的筛选方法，鉴定能够结合CKI(细胞周期蛋白依赖性蛋白激酶抑制剂)的无活性CDK。本发明还提供通过本发明的筛选方法得到的CDK突变体。
摘要（英）：

The present invention concerns a method for modifying the growth characteristics of plants by modulating expression in a plant of a B-type CDK nucleic acid and/or modulating activity and/or levels in a plant of a B-type CDK protein. The invention also relates to transgenic plants having modified growth characteristics, which plants have modulated expression of a B-type CDK nucleic acid and/or modulated activity and/or levels in a plant of a B-type CDK protein relative to expression, activity and/or levels in corresponding wild-type plants. The present invention also provides a novel screeningmethod for the identification of mutant CDKs having enhanced CDK activity relative to corresponding non-mutated CDKs. The present invention also provides a novel screening method for the identification of non-active CDKs that are able to bind to CKIs (cyclin dependent kinase inhibitors). The invention also provides mutant CDKs obtainable by the screening methods according to the invention.
