Grapevine yellow speckle viroid: structural features of a new viroid group.
A single stranded circular RNA was isolated from grapevines infected with yellow speckle disease. The RNA which we have called grapevine yellow speckle viroid (GYSV), contains 367 nucleotide residues and has the potential to form the rod-like secondary structure characteristic of viroids. GYSV has 37% sequence homology with the recently described apple scar skin viroid (ASSV; 330 residues) and ...
متن کاملDe Novo Genome Assembly of Grapevine Yellow Speckle Viroid 1 from a Grapevine Transcriptome
Grapevine yellow speckle viroid 1 (GYSVd1), which is a member of the genus Apscaviroid, causes yellow speckle disease in grapevines. Here, we report the complete de novo genome assembly of GYSVd1 from the grapevine transcriptome and identified 10 single nucleotide polymorphisms of GYSVd1 across the grapevine populations.
متن کاملComplete Genome Sequences of Grapevine Yellow Speckle Viroid 1 and Hop Stunt Viroid Assembled from the Transcriptome of Ixeridium dentatum Plants
Here, we report complete genome sequences of grapevine yellow speckle viroid 1 (GYSVd1) and hop stunt viroid (HSVd), members of the family Pospiviroidae, assembled from the transcriptome data generated from Ixeridium dentatum plants. To our knowledge, this is the first report of GYSVd1 and HSVd in I. dentatum.

Viroids are autonomously replicating, small singlestranded circular RNA molecules that do not code for proteins and may cause disease in infected, susceptible plants. Viroids have the ability to induce both RNA-mediated transcriptional gene silencing (TGS) and posttranscriptional gene silencing (PTGS) in infected plants. Viroid PTGS has also been demonstrated in a wheat germ extract system. A p...
متن کاملتعیین مشخصات مولکولی و تبارزایی ویروئید لکه زردی-1 مو (Grapevine yellow speckle viroid-1) از تاکستان¬های شمال¬غرب کشور
بهمنظور تعیین مشخصات مولکولی و بررسی ساختارهای ثانویه ویروئید لکه زردی- 1 مو، 137 نمونه از تاکستانهای استانهای اردبیل، آذربایجان شرقی و آذربایجان غربی جمعآوری گردید. اسید نوکلئیک کل از بافت برگ نمونهها استخراج و پس از ساخت دیانای مکمل با استفاده از آغازگر ششنوکلئوتیدی تصادفی، طول کامل این ویروئید با روش پیسیآر و با استفاده از آغازگرهای اختصاصی ویروئید لکه زردی -1 مو، تکثیر شد. مح...
