近年来,对生物体内环核苷酸的研究非常重视,许多研究工作表明:环化腺—磷(C-AMP)与环化鸟—磷(C-GMP)分别是在细胞水平上调节控制细胞分化和细胞分裂的物质。环化腺—磷(C-AMP)能促进细胞分化,环化鸟—磷(C-GMP)能促进细胞分裂。有些报告说明,外源环核苷酸在高等植物方面也起着类似作用,Endress用外源C-GMP影响C-AMP磷酸二酯酶的活性。能显示拮抗C-AMP的作用。为了解体C-GMP在花药培养过程中,对小孢子分裂、分化的影响,并观察外源C-GMP对胚状形成有无影响,特设计下列实验。
In recent years, great attention has been paid to the studies on the cyclic nucleotides in living organisms. Many researches show that C-AMP and C-GMP regulate the level of control cells Differentiation and cell division of the material. Cyclic gland-phosphorus (C-AMP) can promote cell differentiation, and circadian bird-phosphorus (C-GMP) can promote cell division. Some reports indicate that exogenous cyclic nucleotides also play a similar role in higher plants and Endress influences the activity of C-AMP phosphodiesterase using exogenous C-GMP. Can show antagonistic effect of C-AMP. In order to disassemble the effect of C-GMP on microspore division and differentiation during anther culture and observe whether exogenous C-GMP has any influence on embryoid formation, the following experiment was designed.
