Comparative Study on Bio-characteristics of Cucumber Mosaic Virus(CMV) Subgroup I and II

doi:10.7668/hbnxb.2009.05.042

Abstract

Abstract: 16 CMV samples from Fujian,Zhejiang,Hunan,Ningxia,Anhui,Shanxi,Henan,Hebei and Binjing were collected and identified by DAS-ELISA with subgroup specific Antisera.The symptoms,pathygenicities,and in vivo stabilities of part of the isolates were compared in Nicotiana tabacum.The results showed that the majority of the CMV samples belong to the subgroup I virus,consisting of 75% of the samples.The symptoms and pathygenicities of subgroup II virus were generally mild and flexible,and adjusted by temperature,humidity and light intensity,suggesting its complex flexibility to the host plant.These results suggested that the subgroup II virus was prone to be neglected or discarded in sample collecting or experimenting.The differences between detection frequency and actual existence,also the ecological significance of subgroup II virus were discussed.

Key words: Cucumber mosaic virus, Subgroup I and II, Bio-characteristic, Comparative study
