• Parasitism and saprotrophic wood decay are two fungal strategies fundamental for succession nutrient cycling in forest ecosystems. An opportunity to assess the trade-off between these is provided by pathogen decayer Heterobasidion annosum sensu lato. We report annotated genome sequence transcript profiling, as well quantitative trait loci mapping, of one member species complex: H. irregulare. Quantitative critical pathogenicity, rich transposable elements, orphan secreted genes, were...
ABSTRACT Forest fires are a common natural disturbance in forested ecosystems and have large impact on the microbial communities forest soils. The response of soil fungal to fire is poorly documented. Here, we investigated community structure function across 152-year boreal chronosequence using high-throughput sequencing internal transcribed spacer 2 (ITS2) region functional gene array (GeoChip). Our results demonstrate that was most diverse soon after declined over time. differences were...
Soil microbial responses to fire are likely change over the course of forest recovery. Investigations on long-term changes in bacterial dynamics following rare. We characterized soil communities across three different times post a 2 152-year chronosequence by Illumina MiSeq sequencing, coupled with functional gene array (GeoChip). The results showed that diversity did not differ between recently and older burned areas, suggesting concomitant recovery after fire. differences time were mainly...
The European Commission requested the EFSA Panel on Genetically Modified Organisms (GMO) to assess whether section 4 (hazard identification) and conclusions of EFSA's
Abstract Genetically modified maize DP23211 was developed to confer control of certain coleopteran pests and tolerance glufosinate-containing herbicide. These properties were achieved by introducing the pmi, mo-pat, ipd072Aa DvSSJ1 expression cassettes. The molecular characterisation data bioinformatic analyses do not identify issues requiring food/feed safety assessment. None identified differences in agronomic/phenotypic compositional characteristics tested between its conventional...
Summary Plant microbiome plays an important role in maintaining the host fitness. Despite a significant progress our understanding of plant achieved recent years, very little is known about effect pathogens on composition microbial communities associated with trees. In this study, we analysed mycobiome different anatomic parts asymptomatic and symptomatic Norway spruce trees naturally infected by Heterobasidion spp. We also investigated primary impact disease fungal communities, which are...
Root and butt rot of conifer trees caused by fungi belonging to the Heterobasidion annosum species complex is one most economically important fungal diseases in commercial plantations throughout Northern hemisphere. We investigated interactions between their host conducting dual RNA-seq chemical analysis on Norway spruce naturally infected spp. analyzed pathogen transcriptome phenolic terpenoid contents trees. Presented results emphasize role phenylpropanoid flavonoid pathways defense...
During their lifetime, conifer trees are exposed to numerous herbivorous insects. To protect themselves against pests, have developed a broad repertoire of protective mechanisms. Many the plant's defence reactions activated upon an insect attack, and underlying regulatory mechanisms not entirely understood yet, in particular trees. Here, we present results our studies on transcriptional response volatile compounds production Scots pine (Pinus sylvestris) large weevil (Hylobius abietis)...
Heterobasidion parviporum is an economically most important fungal forest pathogen in northern Europe, causing root and butt rot disease of Norway spruce (Picea abies (L.) Karst.). The mechanisms underlying the pathogenesis virulence this species remain elusive. No reference genome to facilitate functional analysis available for species. To better understand factor at both phenotypic genomic level, we characterized 15 H. isolates originating from different locations across Finland virulence,...
Mutations are changes in the genetic material that may be transmitted to subsequent generations.Mutations appear spontaneously nature and one of underlying driving forces evolution.In plants, vivo vitro random mutagenesis relies on application physical chemical mutagens increase frequency mutations thus accelerating selection varieties with important agronomic traits.The European Commission has requested EFSA provide a more detailed description techniques types mechanisms involved, able...
Following the submission of dossier GMFF-2022-9450 under Regulation (EC) No 1829/2003 from Bayer Agriculture BV, Panel on Genetically Modified Organisms European Food Safety Authority was asked to deliver a scientific risk assessment data submitted in context renewal authorisation application for insect protected genetically modified maize MON 810, food and feed uses (including pollen), excluding cultivation within Union. The received this contained post-market environmental monitoring...
Abstract Genetically modified maize DP915635 was developed to confer tolerance glufosinate herbicide and resistance corn rootworm pests. These properties were achieved by introducing the ipd079Ea, mo-pat pmi expression cassettes. The molecular characterisation data bioinformatic analyses do not identify issues requiring food/feed safety assessment. None of identified differences in agronomic/phenotypic compositional characteristics tested between its conventional counterpart needs further...
The basidiomycete Heterobasidion annosum sensu lato (s.l.) is considered to be one of the most destructive conifer pathogens in temperate forests northern hemisphere. H. characterized by a dual fungal lifestyle. fungus grows necrotrophically on living plant cells and saprotrophically dead wood material. In this study, we screened genome for small secreted proteins (HaSSPs) that could potentially involved promoting necrotrophic growth during infection process. final list included 58 HaSSPs...
Fungal plant pathogens remain a serious threat to the sustainable agriculture and forestry, despite extensive efforts undertaken control their spread. White root rot disease is threatening rubber tree (Hevea brasiliensis) plantations throughout South Southeast Asia Western Africa, causing mortality severe yield losses. Here, we report complete genome sequence of basidiomycete fungus Rigidoporus microporus, causative agent disease. Our phylogenetic analysis confirmed position R. microporus...
Abstract EFSA was asked by the european Commission to develop criteria as advice for consideration risk assessment of plants produced targeted mutagenesis, cisgenesis and intragenesis. proposes in this statement six main assist these plants. The first four are related molecular characterisation genetic modification introduced recipient plant. evaluate whether any exogenous DNA sequence(s) is/are present (Criterion 1), such sequence derives from breeders' gene pool 2), type integration 3)...
The success of many wood decaying fungi lies in their ability to overcome unfavourable environmental conditions within and outside litter debris. Although so much has been learned about the ecology, taxonomy physiology several basidiomycete fungi, molecular basis for survival a diverse range substrates ecological habitats very little studied. Using decay fungus (Heterobasidion annosum s.s.) as model, we investigated its transcriptomic response when exposed stressors (high low temperature,...
Maize MON 87429 was developed to confer tolerance dicamba, glufosinate, quizalofop and 2,4-D herbicides. The molecular characterisation data bioinformatic analyses do not identify issues requiring food/feed safety assessment. None of the identified differences in agronomic/phenotypic compositional characteristics tested between maize its conventional counterpart needs further assessment, except for levels phytic acid grains, which raise nutritional concerns. GMO Panel does concerns regarding...
