Transmission of Rice stripe virus acquired from frozen infected leaves by the small brown planthopper (Laodelphax striatellus Fallen).
Rice stripe disease, caused by Rice stripe virus (RSV), is one of the most serious rice diseases in temperate and subtropical regions of the world. Since RSV is not transmissible mechanically, an insect transmission test was the original basis for identification of the viral population and cultivar resistance. A simple, rapid and reliable method is described by which virus-free small brown plan...
متن کاملCharacterization of Rice Black-Streaked Dwarf Virus- and Rice Stripe Virus-Derived siRNAs in Singly and Doubly Infected Insect Vector Laodelphax striatellus
Replication of RNA viruses in insect cells triggers an antiviral defense that is mediated by RNA interference (RNAi) which generates viral-derived small interfering RNAs (siRNAs). However, it is not known whether an antiviral RNAi response is also induced in insects by reoviruses, whose double-stranded RNA genome replication is thought to occur within core particles. Deep sequencing of small RN...
متن کاملFive Proteins of Laodelphax striatellus Are Potentially Involved in the Interactions between Rice Stripe Virus and Vector
Rice stripe virus (RSV) is the type member of the genus Tenuivirus, which relies on the small brown planthopper (Laodelphax striatellus Fallén) for its transmission in a persistent, circulative-propagative manner. To be transmitted, virus must cross the midgut and salivary glands epithelial barriers in a transcytosis mechanism where vector receptors interact with virions, and as propagative vir...
متن کاملTranscriptome Analysis of the Small Brown Planthopper, Laodelphax striatellus Carrying Rice stripe virus
Rice stripe virus (RSV), the type member of the genus Tenuivirus, transmits by the feeding behavior of small brown planthopper (SBPH), Laodelphax striatellus. To investigate the interactions between the virus and vector insect, total RNA was extracted from RSV-viruliferous SBPH (RVLS) and non-viruliferous SBPH (NVLS) adults to construct expressed sequence tag databases for comparative transcrip...
متن کاملProbing stimulants from the rice plant towards the smaller brown planthopper, Laodelphax striatellus (FALLEN) (Homoptera: Delphacidae).
When adult males of the smaller brown planthopper, Laodelphax striatellus were fed on 2% crude rice (leaf and stem) extract containing 15% sucrose there were characteristic stylet sheaths deposited on parafilm membrane. Further bioassays with the butanol-soluble fr. of the extract revealed that it is highly effective for the insects. When the butanol fr. was charged on an ODS open column and el...
