Biological control (BC) is defined as the use of living natural enemies, antagonists, or competitors (biological agents) to other organisms. In second half last century, general interest in BC has increased considerably because greater environmental awareness society and implementation integrated pest management (IPM) strategies have pushed towards development environmentally friendly approaches. However, still only rarely used for pathogens (fungi, bacteria, viruses, nematodes,...
Hymenoscyphus fraxineus is an invasive fungal species causing the most serious disease of ashes (Fraxinus spp.) in Europe—ash dieback. The biology this fungus not totally elucidated, neither its relation to saprophytic albidus, native Europe. Our study focused on description seasonal spore dispersal both fungi and meteorological conditions, which needed for more precise effective control disease. For experiment one long time infected mixed forest SE Czech Republic was chosen. A seven-day...
Fungi harbor a vast diversity of mobile genetic elements (MGEs). Recently, novel fungal MGEs, tentatively referred to as 'ambiviruses,' were described. 'Ambiviruses' have single-stranded RNA genomes about 4-5 kb in length that contain at least two open reading frames (ORFs) non-overlapping ambisense orientation. Both ORFs are conserved among all currently known and one them encodes distinct viral RNA-directed polymerase (RdRP), the hallmark gene ribovirian kingdom
Marine oomycetes have recently been shown to be concurrently infected by (−)ssRNA viruses of the order Bunyavirales. In this work, even higher virus variability was found in a single isolate Phytophthora condilina, described member phylogenetic Clade 6a, which isolated from brackish estuarine waters southern Portugal. Using total and small RNA-seq full RdRp 13 different potential novel bunya-like two complete toti-like were detected. All these successfully confirmed reverse transcription...
, an oomycete pathogen causing root and trunk rot of different tree species in Asia, was shown to harbor a rich diversity novel viruses from families. Four
Phytophthora is a long-established, well known and globally important genus of plant pathogens. Phylogenetic evidence has shown that the biologically distinct, obligate biotrophic downy mildews evolved from at least twice. Since, cladistically, this renders ‘paraphyletic’, it been proposed evolutionary clades be split into multiple genera (Runge et al. 2011; Crous 2021; Thines 2023; 2024). In letter, we review arguments for retention generic name with broad circumscription made by Brasier...
We investigated the incidence of RNA viruses in a collection Halophytophthora spp. from estuarine ecosystems southern Portugal. The first approach to detect presence was based on occurrence dsRNA, typically considered as viral molecule plants and fungi. From 73 isolates, two dsRNA-banding patterns were observed (~7 9 kb) few isolates (9.6 %), and, consequently, dsRNA-hosting chosen for performing stranded mRNA sequencing de novo assembling viruses. A total eight putative novel virus species...
Members of the genus Armillaria are widespread forest pathogens against which effective protection has not yet been developed. Due to their longevity and creation large-scale cloning individuals, use mycoviruses as biocontrol agents (BCAs) these could be an alternative. This work describes detection characterization viruses in spp. collected Czech Republic through application stranded total RNA sequencing. A five single-stranded were detected ostoyae A. cepistipes, including family...
Hymenoscyphus fraxineus mitovirus 1 (HfMV1) occurs in the fungus fraxineus, an introduced plant pathogen responsible for devastating ash dieback epidemic Europe. Here, we explored prevalence and genetic structure of HfMV1 to elucidate invasion history both virus fungal host. A total 1298 H. isolates (181 from Japan 1117 Europe) were screened presence this RNA 301 virus-positive subjected partial sequence analysis viral polymerase gene. Our results indicate a high mean (78.7%) across European...
The airborne inoculum of Fusarium circinatum Nirenberg & O’Donnell, the fungal pathogen causing Pine Pitch Canker (PPC), is one main means spread disease in forest stands and nurseries. Since this world-wide known was introduced Europe, its biology newly infested area still remains scarcely known. To shed more light on topic, we set up an experiment a naturally PPC Monterey pine Galicia (NW Spain) with following two goals: (i) to describe seasonal spore dispersal pattern during year...

The basidiomycete Heterobasidion annosum (Fr.) Bref. (=Fomes annosus Cooke), one of the most important pathogens in coniferous forests Europe, Asia, and North America, causes root butt rot. H. was first recorded on Pinus pinaster Ait. (commonly known as Maritime pine) France Great Britain 1961 (4) Portugal 1986 (2). P. is widespread conifer Spain, with more than 700,000 600,000 ha pure mixed stands, respectively. Over last few years, decline observed several stands center Iberian Peninsula....
Abstract Purpose of Review Gremmeniella abietina is a destructive forest pathogen responsible for Scleroderris canker, shoot dieback, defoliation, and tree death in forests nurseries. This review aimed at providing complete description the fungus, its distribution, conditions spread, impact climate change summarising relevant management methods. Due to worldwide importance pathogen, retrospective required summarise lessons learned relation disease, considering application future outbreaks....
Abstract Heterobasidion annosum sensu lato comprises some of the most devastating conifer pathogens conifers. Exploring virocontrol as a potential strategy to mitigate economic losses caused by these fungi holds promise for future. In this study, we conducted comprehensive screening viruses in 98 H. s.l. specimens from different regions Czechia aiming identify inducing hypovirulence. Initial examination dsRNA presence was followed RNA-Seq analyses using pooled RNA libraries constructed and...
