1.Expression pattern of trans-activated virion sense promoter was similar to that of complementary sense promoter with the high activity in both mesophyll and vascular of leaf vein.

其表達方式與互補鏈基因啟動子相似，即在葉肉及葉脈維管組織均有較高的活性。

3.Neuraminidase (NA) is an important protein on the surface of virion and plays an important role in immune and lethality.

神經(jīng)氨酸酶（NA）是流感病毒表面的一種重要蛋白質(zhì)，在免疫和致病方面起重要作用。

4.One important aspect of virus replication mechanisms is the way how virion assembly and budding from cell membrane.

對病毒復(fù)制機制研究的一個重要方面是病毒的組裝和從細(xì)胞表面出芽。

5.VP7, the most conserved protein of the virion, is serogroup-specific antigen.

VP7蛋白在病毒的各蛋白中最保守，是病毒的血清群特異性抗原。
