龙胆子房环斑病毒(GORV)通过与感染GORV的龙胆花粉粒授粉侵染龙胆植株，但不能通过GORV感染的烟草花粉向龙胆植株水平传播。然而，通过感染龙胆花粉的授粉和感染N的授粉，本花龙胆草都感染了该病毒。本特米亚纳波伦。当感染龙胆的花粉粒被放在上面时。萌发的花粉管穿透柱头和花柱(柱头花柱)。病毒感染发生在柱头花柱的穿透过程中，病毒随后系统地传播到母株。另一方面，感染最多的是N。在龙胆柱头上不能萌发，柱头花柱中没有检测到病毒侵染。
Gentian ovary ring-spot virus (GORV) infected gentian plants by pollination with GORV-infected gentian pollen grains, but the virus was not horizontally transmitted to gentian plants by transfer of pollen from GORV-infectedNicotiana benthamianaplants. However,N. benthamianaplants were infected with the virus by pollination with infected gentian pollen as well as by pollination with infectedN. benthamianapollen. When infected gentian pollen grains were placed onN. benthamianastigmas, germinating pollen tubes penetrated into the stigmas and the styles (stigma-style). Virus infection occurred during penetration of the stigma-style, and the virus subsequently spread systemically to the mother plant. On the other hand, most infectedN. benthamianapollen grains failed to germinate on gentian stigmas, and virus infections were not detected in the stigma-style.
