D'Onghia "Detection of citrus psorosis virus (CPsV) and citrus tristeza virus (CTV) by direct tissue blot immunoassay" Options Méditerranéennes (Mediterranean Agronomic Institute), Série B n. 33〕 It is considered the most serious and detrimental virus pathogen of these trees. ==Isolation== The Citrus psorosis virus Egyptian strain (CPsV-EG) was isolated from naturally infected citrus grapefruit (''Citrus paradisi'' Macf.) at ARC. The grapefruit used for CPsV-EG isolatation was found to be free from CTV, CEVd and ''Spiroplasma citri'' by testing with DTBIA, tissue print hybridization and Diene's stain respectively (Ghazal ''et al.,'' 2008). CPsV-EG isolate was transmitted from infected citrus to citrus by syringe and grafting and herbaceous plants by forefinger inoculation and syringe. The woody indicators and rootstocks were differed in response to CPsV-EG isolate which appeared as no-response, response, sensitivity and hypersensitivity. A partial fragment of RNA3 (coat protein gene) of CPsV-EG (–1140bp and –571bp) was amplified by reverse transcription-polymerase chain reaction (RT-PCR) from grapefruit tissues using two sets primers specific CPsV (CPV3 and CPV4) and (PS66 and PS65) respectively. The virus under study was identified as CPsV-EG isolate according to biological, serological and molecular characters. The serological characters represented as the antigenic determinants of CPsV-EG isolate related to monoclonal antibodies specific CPsV strain where as appeared precipitation reaction by DAS-ELISA and DTBIA (Ghazal ''et al.,'' 2008). CPsV-EG was detected on the basis of biological indexing by graft inoculation which gave oak leaf pattern (OLP) on Dweet tangor and serological assay by DAS-ELISA using Mab specific CPsV. CPsV-EG was reacted with variable responses on 16 host plants belonging to 6 families. Only 8 host plants are susceptible and showed visible external symptoms which appeared as local, systemic and local followed by systemic infections (Ghazal ''et al.,'' 2008). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Citrus psorosis virus」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
