There are two types of maturation according to our observation.One is nucleocapsids obtained its tegument in the nucleus and enveloped from the inner nuclear membrane.Another is nucleocapsids entered cytoplasm through nuclear membrane,then obtained their tegument in the cytoplasm,enveloped from the plasma membrane,finally released by necrosis,exocytosis or other ways.

病毒成熟有两种方式：一为细胞核内核衣壳在核内获得皮层，通过核内膜获得囊膜成为成熟病毒；二为核内核衣壳通过内外核膜进入胞浆，核内和胞浆内的核衣壳在细胞浆中获得皮层，然后在各种质膜上获得囊膜，最后成熟病毒通过细胞破裂或其他方式释放到细胞外。

The genetic diversity of 23 maize inbred lines and one teosinte accession was analyzed based on microsatellite and AFLPs markers.
