Temperature is an important environmental factor influencing plant development in natural and diseased conditions. The growth rate of plants grown at C27°C more rapid than for 21°C. Thus, temperature affects the pathogenesis progression individual plants. We have analyzed effect conditions (either 21°C or 27°C during day) on accumulation virus satellite RNA (satRNA) Nicotiana benthamiana infected by peanut stunt (PSV) with without its satRNA, four time points. In addition, we extracted...

Abstract Background Root-knot nematodes (RKNs) – Meloidogyne spp. are a group of distributed worldwide that infect monocotyledonous and dicotyledonous crop species. Plant responses to RKNs have been described in many studies various host plants. In the course parasitism, induce transcriptional reprogramming cells establish giant cells. Nematode attack induces mechanisms plants, including pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) effector-triggered (ETI). Research...

Potato mop‐top virus (PMTV; genus Pomovirus ; family Virgaviridae ) is transmitted by the soil‐borne Spongospora subterranea f.sp. , a protoctist that causes powdery scab on potato. PMTV distributed widely in potato growing areas South and North America, Japan northwestern Europe. This article reviews current knowledge detection, distribution control of with focus Baltic Sea region. Since 1980s, has caused great economic losses to production Nordic countries (Norway, Sweden, Denmark...

Systemic acquired resistance (SAR) induction is one of the primary defence mechanisms plants against a broad range pathogens. It can be induced by infectious agents or synthetic molecules, such as benzo(1,2,3)-thiadiazole-7-carbothioic acid S-methyl ester (BTH). SAR associated with increases in salicylic (SA) accumulation and expression marker genes (e.g., phenylalanine ammonia-lyase (PAL), pathogenesis-related (PR) protein family, non-expressor PR (NPR1)). Various types pathogens pests...

In 2003 and 2004, unusual disease symptoms, including severe stunting, malformation, necrosis of the leaves on tomato cv. Grace, were observed in Wielkopolska Region Poland. The appeared to be associated with presence greenhouse whitefly Trialeurodes vaporariorium. An electron microscopic examination a negatively stained leaf-dip preparation from an infected plant showed spherical virus particles approximately 25 28 nm diameter. (designated Wal'03) was shown vectored efficiently (100%) by T....

Thrips palmi (from the order Thysanoptera) is a serious insect pest of various crops, including vegetables, fruits and ornamental plants, causing significant economic losses. Its presence constitutes double threat; not only does T. feed on it also vector for several plant viruses. originated in Asia, but has spread to North Central America, Africa, Oceania Caribbean recent decades. This species been sporadically noted Europe under quarantine regulation European Union. For non-specialists its...

Nowadays, plant protection against viral diseases is one of the most challenging tasks faced by modern agriculture. One possible ways utilization systemic acquired resistance phenomenon. In this approach biological or chemical factors interact with plants and stimulate their immune system infections before infection occurs. This paper presents 11 ionic derivatives benzo[1.2.3]thiadiazole-7-carboxy-S-methyl ester, a synthetic inducer, counterions specifically selected to modify physical...

Wheat (Triticum aestivum) is one of the most economically important crops in world. During routine monitoring wheat pest, cereal leaf beetle (CLB, Oulema melanopus, Coleoptera, Chrysomelidae), Greater Poland region, it was observed that some leaves wounded by CLB also displayed brownish lesions with clear margins and yellow halo, disease symptoms resembling a bacterial infection. The aim this study therefore to investigate those establish causal agent disease. identification based on results...

Plant resistance induction is one of the most promising ways to support plants in fights against pathogens, especially viruses, due fact there are no plant protection agents acting directly on them. Certain chemicals, including benzo[1.2.3]thiadiazole-7-carbothioic acid, S-methyl ester (BTH) and its derivatives, were discovered as effective inducers immunity. In this article, new BTH form organic salts composed cations based inducer anions introduced order modify physical (solubility water,...

Positive-sense single-stranded [ss(+)] plant RNA viruses are obligate intracellular parasites that infect many agriculturally important plants, leading to severe losses of crops. All known characterized by small genomes encoding a limited number multifunctional viral proteins. Viral pathogens considered be absolutely dependent on host. To facilitate genomic replication, must recruit numerous host proteins and other factors. The replication process depends the virus – protein-protein,...

Summary Avena fatua of the family Poaceae is one most common and economically damaging grass weeds. Resistance to herbicides that inhibit acetyl‐coenzyme A carboxylase acetolactate synthase activities has recently been detected in A. . The resistance may be due mutations herbicide targets and/or enhanced metabolism resulting from changes gene expression, including genes involved detoxifying active ingredients. To analyse stable housekeeping must experimentally determined used for data...
