...n: justify; ">Two citrus viroids, Citrus exocortis viroid (CEVd) and Hop stunt viroid (HSVd), have been reported decades ago without further pathological and genetic researches in Taiwan. Here, bioassay, multiplex RT-PCR and multiplex real-time RT-PCR were used to detect the current status of the two viroids showing HSVd was more prevalent than CEVd and simultaneous infections were common in field. Uneven distributions of bo...

...om development of citrus viroids. The geographical distribution of the gummy bark disease in some world countries depend on high temperatures for viroid-symptom expression. So, correlation between climatic factors and gummy bark disease through GIS is studied. We designed a satellite map for the gummy bark disease distribution all over the world using the previous registered results. Superimposed maps of BIOCLnvf annual Mintemperature, Max-Temperature and the ...

...t-align: justify;">Three viroids: Citrus exocorlis viroid (CEVd), Hop stunt viroid (HSVd), and Potato spindle tuber viroid (PSTVd) can be detected in naturally infected grapevine by biological indexing and molecular methods. In the present study, direct tissue-printing and dot-blot on the membranes, procedures has been applied on a large scale for an initial screening of HSVd, CEVd and PSTVd in Egypt. The results showed that the tissue print assays allowed cle...

...ria, nematodes, viruses, viroids, fungi, and phytoplasmas. In Pakistan, significant viral infections, particularly PVY, PMTV, PLRV, PVM, PVS, PVA, and PVX, are of serious concern, with alarmingly high prevalence of PLRV, PVX, and PVY in key potato-growing regions. Effective management of these viral threats is challenging due to the lack of direct chemical controls, underscoring the importance of prevention as the primary strategy. Rapid and precise detection ...
