RNA silencing is a sequence-specific gene regulation mechanism that in plants also acts antiviral. In order to counteract antiviral RNA silencing, viruses have evolved RNA silencing suppressors (RSS). In the case of tospoviruses, the non-structural NSs protein has been identified as the RSS. Although the tomato spotted wilt virus (TSWV) tospovirus NSs protein has been shown to exhibit affinity ...

In the regions of Campinas and Sumaré, São Paulo, Brazil, hidroponically grown crops of Lettuce (Lactuca sativa) cv. Verônica, which showed virus-like symptoms were examined by electron microscope, biological, serological and molecular tests. Pleomorphic, enveloped particles (80-100 nm in diameter) were always detected in these samples. Experimentally inoculated host plants, including lettuce, ...

This paper describes the R package EpiILMCT, which allows users to study spread of infectious disease using continuous time individual level models (ILMs). The provides tools for simulation from ILMs that are based on either spatial demographic, contact network, or a combination both them, and graphical summarization epidemics. Model fitting is carried out within Bayesian Markov Chain Monte Car...

Fusarium oxysporum f. sp. lycopersici, Verticillium spp., and nematodes, as well virus diseases that negatively affect production with limited chemical control cause significant losses in greenhouse tomato cultivation. The practical effective side of controlling is genetic by breeding. Using a genomic approach for plant breeding more sustainable way to disease pests. development the resistant l...

Germination and vigor are physiological components of seed quality that contribute to a successful plant emergence under wide range environmental conditions. Many biotic abiotic factors can affect quality. Tomato spotted wilt virus (TSWV) causes one the most relevant problems in peanut (Arachis hypogaea L.), tomato disease (TSW). Although TSW is not transmitted by seed, presence symptoms on coa...
