Two mutant strains of beet necrotic yellow vein virus (BNYVV) containing deletion mutants of RNA-2 were produced during serial passage in mechanically inoculated Tetragonia expansa leaves. The mutant strains were referred to as S-0a (RNA-1 + 2a) and G-0b (RNA-1 + 2b). RNA-2a and RNA-2b were about 4.3 kb and 4.2 kb in length, respectively, whereas normal sized RNA-2 was about 4.8 kb in length. I...
ویروس پیچیدگی شدید بوته چغندرقند ((Beet severe curly top virus, BSCTV، که اخیراً به عنوان سویه شدید ویروس پیچیدگی بوته چغندرقند معرفی شده است و ویروس ایرانی پیچیدگی بوته چغندرقند (Beet curly top Iran virus, BCTIV) دو عامل اصلی ایجادکننده بیماری پیچیدگی بوته در چغندرقند و چندین میزبان دولپهای دیگر در ایران محسوب میشوند. تنوع ژنتیکی و پراکنش این ویروسها در ارتباط با میزبان، منطقه جغرافیایی و سن...
Sugar beet pulp is a by-product from the processing of sugar beets into sugar. Beet pulp is extracted grounded sugar beet. It is used as livestock feed and it can be fed fresh, dried and ensiled (fermented beet pulp). Sugar beet pulp is a by-product from the processing of sugar beet which is used as fodder for cattle and other livestock. It is supplied either as dried flakes or as compressed pe...
BACKGROUND Rhizomania is one of the most devastating diseases of sugar beet. It is caused by Beet necrotic yellow vein virus (BNYVV) transmitted by the obligate root-infecting parasite Polymyxa betae. Beta macrocarpa, a wild beet species widely used as a systemic host in the laboratory, can be rub-inoculated with BNYVV to avoid variation associated with the presence of the vector P. betae. To b...
Next-generation sequencing (NGS) has been applied to plant virology since 2009. NGS provides highly efficient, rapid, low cost DNA, or RNA high-throughput sequencing of the genomes of plant viruses and viroids and of the specific small RNAs generated during the infection process. These small RNAs, which cover frequently the whole genome of the infectious agent, are 21-24 nt long and are known a...
abstract polymyxa betae is an obligate parasite and has a worldwide distribution. this fungus is a soil-borne root endoparasite in some plant families such as portulaceae, chenopodiaceae and amaranthaceae. this fungus is the vector of many plant viruses such as beet necrotic yellow vein virus (bnyvv) which causes the disease known as rhizomania. bnyvv is the most economical important viral dise...
