Europe is the world largest grape producer, but in recent years, report of diseases due to infection by grapevine trunk pathogens (GTPs) becoming one main constraints for viticulture. Among (GTDs), esca syndrome most complex, characterized simultaneous several fungi, which leads important reduction yield and quality. Previous characterization fungal isolates associated with recognition at least three players: Phaeocremonium minimum, Phaemoniella chlamydospora Fomitiporia mediterranea. Here...
Zoysia japonica, in Brazil, is commonly infected by Rhizoctonia solani (R. solani) humid and cool weather conditions. Eight isolates of R. solani, previously identified as belonging to the AG2-2 LP anastomosis group, isolated from samples large path symptoms, were collected three counties São Paulo state (Brazil) investigated for presence mycoviruses. After detection double-strand RNA (dsRNA) all samples, RNA_Seq analysis ribosomal RNA-depleted total vitro cultivated mycelia was performed....
Grapevine is one of the most important and globally widespread fruit species, with a high impact on economy many countries but an intense environmental effect. Therefore, new environmentally friendly defense strategies against fungal pathogens are needed for more sustainable agriculture. A novel emerging approach spray-induced gene silencing (SIGS), which concerns exogenous application double-stranded RNA (dsRNA) inducing enhanced plant resistance pathogens. Here, we tested ability SIGS to...
So far there is no record of a specific virus able to infect both fungal and plant hosts in nature. However, experimental evidence shows that some RdRPs are perform replication trans genomic or DI RNAs the yeast Saccharomyces cerevisiae. Furthermore, tobacco mosaic was recently shown replicate filamentous ascomycetous fungus. Thus, at least experimentally, viruses can fungi. Endophytic fungi have been reported from many plants several these contain viruses. Here we tested if mycoviruses...
This paper reports the first biological characterization of a bona fide plant mitovirus in an important crop, Chenopodium quinoa , providing data supporting that mitoviruses have typical features cryptic (persistent) viruses. We, for time, demonstrate are associated with mitochondria plants. In contrast to fungal mitoviruses, not substantially affected by antiviral silencing pathway, and most abundant small RNA length is 16 nt.
Abstract In this study, we analysed a total of 16 libraries from over 150 grapevine leaf and grape samples infected with Plasmopara viticola (downy mildew grapevine) to characterise the virome associated oomycete. Samples were collected in five distinct regions Italy four different Spain, representative pedoclimatic conditions cultivars during 2018 growing season. Due metagenomics nature (containing at least both downy hyphae spores, cells residues), able assemble several plant viruses few...
The importance of plants as complex entities influenced by genomes the associated microorganisms is now seen a new source variability for more sustainable agriculture, also in light ongoing climate change. For this reason, we investigated through metatranscriptomics whether taxa profile and behaviour microbial communities with wood 20-year-old grapevine are health status host. We report first time metatranscriptome from tissue real environment, highlighting that approach able to define...
Citrus sudden death (CSD) has caused the of approximately four million orange trees in a very important citrus region Brazil. Although its etiology is still not completely clear, symptoms and distribution affected plants indicate viral disease. In search for viruses associated with CSD, we have performed comparative high-throughput sequencing analysis transcriptome small RNAs from CSD-symptomatic -asymptomatic using Illumina platform. The data revealed mixed infections that included tristeza...
Summary We attempted to transfect six recently characterized virus species protoplasts of Penicillium janczewskii and Chryphonectria parasitica . None the recovered P colonies was positive for transfected viruses, but aurantiogriseum partiti‐like 1 (PaPLV1) detected in three distinct regenerated C colonies. screened phenotype infected strains up 45 different conditions combining media, salinity temperatures: our results show that grow slower than virus‐ free most tested with exception...
Several recent reports have highlighted some of the mechanisms involved in enhanced tolerance to abiotic stresses induced by root-associated microorganisms, although additional efforts are still required exploit and optimize these strategies. Particularly, arbuscular mycorrhizal fungi (AMF) play an important role as “bio-fertilizing microorganisms”, establishing mutualistic symbioses with roots most crops. In this work, different microbial inocula (a single AMF species, a combination three...
Abstract In the past years, breeding programs have been mainly addressed on pushing commercial features, forgetting important traits, such as those related to environmental stress resilience, that are instead present in wild relatives. Among traits neglected by processes, ability recruit beneficial microorganisms recently is receiving a growing attention due its potentiality. this context, review will provide spotlight critical issues of anthropocentric point view that, until now, has...
Abstract Legumes maintain soil fertility thanks to their associated microbiota but are threatened by climate change that causes microbial community structural and functional modifications. The core microbiome with different chickpea lentil genotypes was described after an unexpected climatic event. Results showed bulk microbiomes varied significantly between two sampling time points, the first immediately rainfall second 2 weeks later. Rhizobia were of more productive in terms flower fruit...
SUMMARY The main bottleneck in the application of biotechnological breeding methods to woody species is due vitro regeneration recalcitrance shown by several genotypes. On other side, species, especially grapevine ( Vitis vinifera L.), use most pesticides and expensive inputs agriculture, making development efficient approaches genetic improvement absolutely urgent. Genome editing an extremely promising technique particularly for wine grape genotypes, as it allows modify desired gene a...
To date, no demonstration of a direct correlation between the presence mycoviruses and quantitative or qualitative modulation mycotoxins has been shown. In our study, we transfected virus-free ochratoxin A (OTA)-producing isolate Aspergillus ochraceus with purified from different A. Penicillium aurantiogriseum. Among tested, only virus (AoV), partitivirus widespread in ochraceus, caused specific interaction that led to an overproduction OTA, which is regulated by European Commission second...
Abstract Taxonomy is partly a subjective matter, but it instrumental for ecological, behavioural and especially conservation studies. According to the International Union Conservation of Nature, goat‐antelopes (Bovidae: Rupicaprini tribe) number 13 species, 62% which are ‘Threatened’ or ‘Near Threatened’ with extinction. During recent decades, extant species – in endemic Asian genera (goral: six Naemorhedus spp.; serow: seven Capricornis spp.) has been inflated. We have revised taxonomy...
Along with the ongoing climate change, drought events are predicted to become more severe. In this context, spray-induced gene silencing (SIGS) technique could represent a useful strategy improve crop stress resilience. A previous study demonstrated that Arabidopsis mutants for glutathione S-transferase (GST) had increased abscisic acid (ABA) levels and activated antioxidant system, both features improved Here, we used SIGS target putative grape GST (VvGST40). Then, ecophysiological,...
