Viruses, viroids and vectors
On San Miguel, one of the smallest of the 7 000 islands of the Philippines, a few coconut palms were slowly dying in 1928. Ten years later, 50 000 palms on this island were dead or dying. The disease seemed to be limited to a certain area and affected only coconut palms. No bacteria or fungi were found to be associated with the dying palms. The disease, believed to be caused by a virus, began t...
متن کاملComparative studies of two viroids: analysis of potato spindle tuber and citrus exocortis viroids by RNA fingerprinting and polyacrylamide-gel electrophoresis.
Highly purified isolates of potato spindle tuber viroid (PSTV) from Lycopersicon esculentum cv. Rutgers and citrus exocortis viroid (CEV) from Gynura aurantiaca have been compared. Two-dimensional fingerprinting analysis of PSTVand CEV-RNA labeled in vitro with lzrI has demonstrated that (i) each of these RNA species has a complexity compatible with the size estimate of 250X350 nucleotides and ...
متن کاملNucleotide sequence and structural features of the group III citrus viroids.
The nucleotide sequence and secondary structure of two representative variants from the Group III citrus viroids. CVd-IIIa (297 bases) and CVd-IIIb (294 bases) were determined. The variants are related to the apple scar skin viroid (ASSVd) family. Although smaller in size than any of the ASSVd-related viroids, the central conserved region as well as most of the terminal conserved region of ASSV...
متن کاملRegulation of pathogenicity in hop stunt viroid-related group II citrus viroids.
Nucleotide sequences were determined for two hop stunt viroid-related Group II citrus viroids characterized as either a cachexia disease non-pathogenic variant (CVd-IIa) or a pathogenic variant (CVd-IIb). Sequence identity between the two variants of 95.6% indicated a conserved genome with the principal region of nucleotide difference clustered in the variable (V) domain. Full-length viroid RT-...
متن کاملNext Generation Sequencing for Detection and Discovery of Plant Viruses and Viroids: Comparison of Two Approaches
Next generation sequencing (NGS) technologies are becoming routinely employed in different fields of virus research. Different sequencing platforms and sample preparation approaches, in the laboratories worldwide, contributed to a revolution in detection and discovery of plant viruses and viroids. In this work, we are presenting the comparison of two RNA sequence inputs (small RNAs vs. ribosoma...
