花器形态和花药发育的解剖学观察表明，RGCMS S45A和RGCMS 117A中表现波里马细胞质雄性不育的植株，其花器形态和花药发育的解剖学特点与polCMS相同，即在高温条件下，花瓣较小，表现彻底不育，无花粉囊的分化；在低温条件下，花瓣变大，表现部分雄性不育，可分化出 1～ 4个花粉囊，并产生一定数量可育花粉。

The Promega commercial DNA extraction kit was used as control. Results The Promega kit resulted in a higher copy number of COWP gene[（6.45-9.86）×106]than that of Generay commercial DNA kit [（2.38-3.69）×106 ], 5% guanidine thiocyanate[（1.27-21.29）×105] or 2% Triton X-100 [（2.06-866.70）×103], respectively.

结果 Promega试剂盒的裂解液裂解隐孢子虫卵囊的效果最好，纯化所得卵囊COWP基因拷贝数可达（6.45～9.86）×106；其他依次为捷瑞试剂盒的裂解液[（2.38～3.69）×106]、5%异硫氰酸胍[（1.27～21.29）×105]和2% Triton X-100[（2.06～866.70）×103]。

Through differential centrifugation and sucrose density gradient centrifugation,tono plast vesicles were isolated from suspension-cultured Populus euphratica cells broken by mortar and pestIe,blender or ultrasonic homogenizer.The sensitivities of H+-ATPase to NO-3,VO3-4 andNaN3,as well proton pnmping activities of membrane-bound pyrophosphatases demonstrated that tonoplast vesicles mainly distributed on the interface of 0％～25％of sucrose.
