Results It is observed that the secretion of δ-hemolyrin is various in different S. aureus strains and different growth phases, the curve of δ-hemolysin secretion is synchronous with that of bacterial growth and can be divided into three phases.

结果 在检测的8株金黄色葡萄菌中，δ溶血素的分泌存在着明显的菌株间的差异；其分泌的量－时间曲线呈现"S"型，可分为分泌量微量增加、快速增加、平缓增加三个时期。

In general, every 9-11 vegetative cells there was one heterocyst, But to wild-type filaments, every 12 vegetative cells. Mp22 has strong phenotype. Cells grow slowly under BG11 medium, BG11〓 medium, iron-deficiency condition and NaCl stress conditions in contrast with wild-type.

在BG11〓培养条件下，突变株也能诱导异形胞，但异形胞发育却有差异，端生异形胞很多，一般每隔9-11个营养细胞就有一个异形胞，但野生株一般每隔12个以上细胞才有一个异形胞。

The study suggest:(1) The observation of satellites in root tip and multiplex PCR makers could accurately identify the homozygous and the heterozygosis of 1BL/1RS translocation.(2) Through the restoring degree we could confirm the success of the transfer. The combination of the restoring degree and the agronomy property could increase the efficiency of practical application.(3) This study proposed the transformation from the physiological male sterile to the genetic male sterile, and then establish a method of utilize the strong superiority crosses.

其中复合引物PCR更适合于回交后代中大量目标种子的筛选；(2)恢复基因转育后代定株与不育系测交，依据测交恢复度可准确确定恢复基因在回交后代的延续，恢复基因定株定向转育与性状选择结合可大大提高转育后代的实际应用效果；(3)本研究提出的粘类小麦雄性不育恢复基因Rfv1定向转育体系，可有效地实现小麦由化控强优势组合向三系强优势组合的定向转化，即生理型不育途径向遗传型不育途径的定向转化，进而建拓一套杂交小麦强优势组合多途径利用新体系。

Results A stable heredity heterozygote strain with an ADH2 allele deletion was obtained.
