Two types of Grapevine yellow speckle viroid 1 isolated from commercial grapevine had the nucleotide sequence of yellow speckle symptom-inducing type
Journal of General Plant Pathology 66 (1), 68-70
Abstract: Grapevine yellow speckle viroid 1 (GYSVd 1) was first detected in Japan from commercial grapevines. The viroid seems to be spreading in Japanese commercial vineyards but without causing noticeable disease symptoms. Two Japanese GYSVd 1 isolates from the cultivars Campbell and Steuben were sequenced. The Campbell isolate is included in the type 2 variant of GYSVd 1, and the Steuben isolate is included in the type 3. Both of the isolates were grouped into the yellow speckle-inducing variants in the nucleotide sequence ; however, the etiological importance of this viroid on the viticulture of Japan has not yet been determined.
