中文摘要: |
对123个柑橘衰退病毒柚分离株进行p25/Hinf1 RFLP分析明确:样品中,单一p25/Hinf1 RFLP组群样品占样品总量的82.9%,说明我国田间受侵染柚类中柑橘衰退病毒株系相对较为单一;RFLP组群6的样品占样品总量的79.7%,说明目前柚类生产上的优势流行株属于p25/Hinf1 RFLP组群6,初步认定为强毒株系;柑橘衰退病毒株柚分离株S102、S104、S106、S108属于p25/Hinf1 RFLP组群5,初步认定是弱毒株系。 |
英文摘要: |
Citrus Tristeza Virus(CTV) is one of the most economically important pathogen of citrus in many citrus producing areas of the world.Pummelo dwarf caused by CTV has become a serious problem in China recently.In order to discover their pathogenic characteristics,123 CTV isolates infecting pummelo were studied by p25/Hinf1 RFLP assay.Single p25/Hinf1 RFLP groups were detected in 82.9% of the 123 samples,and the dominant group was p25/Hinf1 RFLP group 6,which accounted for 79.7% of the total.There were 4 isolates belonging to p25/Hinf1 RFLP group 5,which could be mild CTV strains and should be further studied. |
