Packaged within geminate particles, the genomes of geminiviruses are single-stranded circular DNAs that are replicated mainly by a rolling circle mechanism, characteristic to prokaryotes. Previous researches have indicated that geminiviruses can generate various DNA replication forms in bacteria, suggesting that geminiviruses possess the potential to regulate the expression of certain viral genes in prokaryotic systems.
双生病毒在植物细胞中是主要以原核生物形式的rolling circle replication方式做复制，而先前研究指出双生病毒可以在原核系统里进行复制，因此，双生病毒基因体中应具有在原核系统中亦能表现的调控机制，除了已知的基因外，是否有其他未知的基因参与这项机制仍不清楚。

In the current study, a series of cationic α-helical peptides of 20 a.a. were designed and synthesized based on four structural parameters, including charge, polar angle, hydrophobicity, and hydrophobic moment. Several methods were performed to describe the influence of these parameters on the antimicrobial and hemolytic activity, and on the permeabilizing effect on model membranes. The potential of these parameters to increase the antibacterial activity and to improve the prokaryotic selectivity is assessed.
本实验利用自行设计合成的人工抗菌胜肽当模型，固定长度为 20 个胺基酸，改变其电荷、极性角度、疏水性及疏水性矩等四种结构特性，并利用其对各种不同病原菌之抗菌活性及对兔子红血球细胞的溶血活性来研究其结构特性的改变对其抗菌活性、选择性及微脂体膜的渗透性之影响，以期望改变结构参数能增加抗菌活性及对原核的选择性。

Addition of 3μg/ml CB to CM containing 0.625μg/ml CHX increased the proportion of oocytes with two pronuclei (38. 9% vs 15. 1%, P＜0.05) and developed into morulae/blastocysts (40.7% vs 26. 8%, P＜0.05), but did not affect the percentage of oocytes cleaved and total pronucleus rate.
如果在含有0.625μg/ml CHX中添加3μg/ml CB，可明显提高双原核的形成率（38.9％vs 15.1％，P＜0.05）和桑椹胚/囊胚发育率（40.7％vs 26.8％，P＜0.05），但对其激活分裂率和总原核形成率无明显影响（P＞0.05）。
