Small non-coding satellite RNAs - the 'game changers' at the virus-host plant interaction?

Satellite RNAs (satRNAs) are RNA molecules associated with many plant viruses and fully dependent on them for replication, encapsidation, and movement within the plant or transmission from plant to plant. Their classification is based on their length, functional protein-coding capacity, and RNA structure (whether linear or circular). They have been of interest for a long time as some of them, in particular systems, cause significant changes in the pathogenesis and epidemiology of plant viruses.

Cereal leaf beetle-associated bacteria enhance the survival of their host upon insecticide treatments and respond differently to insecticides with different modes of action.

The cereal leaf beetle (CLB, Oulema melanopus) is one of the major cereal pests. The effect of insecticides belonging to different chemical classes, with different mechanisms of action and the active substances' concentrations on the CLB bacterial microbiome, was investigated. Targeted metagenomic analysis of the V3-V4 regions of the 16S ribosomal gene was used to determine the composition of the CLB bacterial microbiome.

Dicer-Like Protein 4 and RNA-Dependent RNA Polymerase 6 Are Involved in Tomato Torrado Virus Pathogenesis in Nicotiana benthamiana.

Tomato torrado virus (ToTV) is a type member of the Torradovirus genus in the Secoviridae family known to cause severe necrosis in susceptible tomato varieties. ToTV also infects other Solanaceae plants, including Nicotiana benthamiana, where it induces distinctive disease symptoms: plant growth drop with the emergence of spoon-like malformed systemic leaves. Virus-induced post-transcriptional gene silencing (PTGS) is significant among plant defense mechanisms activated upon virus invasion.

The Effect of Benzo(1,2,3)-thiadiazole-7-carbothioic Acid -Methyl Ester (BTH) and Its Cholinium Ionic Liquid Derivative on the Resistance Induction and Antioxidant Properties of Tomato ( L.).

Tomatoes are one of the most important vegetables thanks to their taste attributes and nutritional value. Their cultivation is threatened by various pathogens including viruses. The application of resistance inducers (RI), such as benzo(1,2,3)-thiadiazole-7-carbothioic acid -methyl ester (BTH) may be used to enhance plant performance against viruses.

Herbicide resistance status impacts the profile of non-anthocyanin polyphenolics and some phytomedical properties of edible cornflower (Centaurea cyanus L.) flowers.

To ensure sufficient food supply worldwide, plants are treated with pesticides to provide protection against pathogens and pests. Herbicides are the most commonly utilised pesticides, used to reduce the growth of weeds. However, their long-term use has resulted in the emergence of herbicide-resistant biotypes in many weed species.
