Detection of Grapevine rupestris stem pitting-associated virus in the vineyards of Southeastern Anatolia and Eastern Mediterranean in Turkey

In this study, it was aimed to survey the vineyards for the presence of the Grapevine rupestris stem pitting-associated virus (GRSPaV) in the Southeastern Anatolia (Gaziantep, Adıyaman and Kilis) and Eastern Mediterranean Region (Kahramanmaraş, Hatay, Adana and Mersin) with a newly designed primer pair. A total of 381 samples from 96 vineyards were collected and analysed by RT-PCR technique. Of the 381 samples collected, 40 were found to be infected with GRSPaV. The prevalence rates of GRSPaV were respectively calculated as follows: Kahramanmaras (4.46%), Kilis (2.36%), Adıyaman (1.58%), Gaziantep (1.31%), Adana (0.53%), Mersin (0.26%) and Hatay (0%). As a result, it has been determined that the virus has a significant prevalence in Southeastern Anatolia and Eastern Mediterranean Region

Variants of Coconut cadang-cadang viroid isolated from an African oil palm (Elaies guineensis Jacq.) in Malaysia

The original publication can be found at www.springerlink.comVariants of Coconut cadang-cadang viroid have been identified in a plantation oil palm growing in Malaysia. Three size classes are described, comprising 297, 293, and 270 nt. Compared with the 296-nt form of coconut cadangcadang viroid (CCCVd), all variants substituted C31→U in the pathogenicity domain and A175→C in the right-hand terminus. Other mutations and deletions accounted for the different sizes. These are the first sequences reported for variants of Coconut cadang-cadang viroid in a species other than coconut palm, and this is the first evidence that variants closely related to CCCVd occur outside the Philippines
