Artificial microRNA-mediated virus resistance in plants.
RNA silencing in plants is a natural defense system against foreign genetic elements including viruses. This natural antiviral mechanism has been adopted to develop virus-resistant plants through expression of virus-derived double-stranded RNAs or hairpin RNAs, which in turn are processed into small interfering RNAs (siRNAs) by the host's RNA silencing machinery. While these virus-specific siRN...
متن کاملExploring antibiotic resistance genes and metal resistance genes in plasmid metagenomes from wastewater treatment plants
Plasmids operate as independent genetic elements in microorganism communities. Through horizontal gene transfer (HGT), they can provide their host microorganisms with important functions such as antibiotic resistance and heavy metal resistance. In this study, six metagenomic libraries were constructed with plasmid DNA extracted from influent, activated sludge (AS) and digested sludge (DS) of tw...
متن کاملTetracycline resistance genes in activated sludge wastewater treatment plants.
The development and proliferation of antibiotic resistance in pathogenic, commensal, and environmental microorganisms is a major public health concern. The extent to which human activities contribute to the maintenance of environmental reservoirs of antibiotic resistance is poorly understood. In the current study, wastewater treatment plants (WWTPs) were investigated as possible sources of tetr...
متن کاملDynamic Model of Virus Transmission in Plants
In the study of viral diseases in plants, the immune response of the plant plays a basic role. In this paper, a mathematical model based on differential equations system with time delay for the immune response of the plant is introduced. As follows, the dynamical behavior of the model in equilibrium points is investigated. At the end, a plant in two different modes, organic and non- organic is ...
متن کاملNanobody‐mediated resistance to Grapevine fanleaf virus in plants
Since their discovery, single-domain antigen-binding fragments of camelid-derived heavy-chain-only antibodies, also known as nanobodies (Nbs), have proven to be of outstanding interest as therapeutics against human diseases and pathogens including viruses, but their use against phytopathogens remains limited. Many plant viruses including Grapevine fanleaf virus (GFLV), a nematode-transmitted ic...
