Traditional morphological and biological species concepts are difficult to apply closely related, asexual taxa because of the lack an active sexual phase paucity characters. Phylogenetic such as genealogical concordance phylogenetic recognition (GCPSR) have been extensively used; however, methods that incorporate gene tree uncertainty into may more accurately objectively delineate species. Using a worldwide sample Alternaria alternata sensu lato, causal agent citrus brown spot, evolutionary...
Human activity has been shown to considerably affect the spread of dangerous pests and pathogens worldwide. Therefore, strict regulations international trade exist for particularly harmful pathogenic organisms. Phytophthora plurivora, which is not subject regulations, a plant pathogen frequently found on broad range host species, both in natural artificial environments. It supposed be native Europe while resident populations are also present US. We characterized hierarchical sample isolates...
Most Alternaria spp. are considered asexual but recent molecular evolution analyses of mating-type genes show that the mating locus is under strong purifying selection, indicating a possible role in sexual reproduction. The objective this study was to determine mode reproduction an alternata sensu lato population causing citrus brown spot central Florida. Mating type each isolate determined, and isolates were sequenced at six putatively unlinked loci. Three genetically distinct...
Summary Since the myrtle rust pathogen ( Austropuccinia psidii ) was first reported (as Puccinia in Brazil on guava Psidium guajava 1884, it has been found infecting diverse myrtaceous species. Because A . recently spread rapidly worldwide with an extensive host range, genetic and genotypic diversities were evaluated within among populations its putative native range other areas of emergence Americas Hawaii. Microsatellite markers revealed several unique multilocus genotypes (MLGs), which...
Abstract Cercosporidium personatum (CP) causes peanut late leaf spot (LLS) disease with 70% yield losses unless controlled by fungicides. CP grows slowly in culture, exhibiting variable phenotypes. To explain those variations, we analyzed the morphology, genomes, transcriptomes and chemical composition of three morphotypes, herein called RED, TAN, BROWN. We characterized, for first time CP, anthraquinone (AQ) precursors dothistromin (DOT), including averantin, averufin, norsolorinic acid,...
Microbes encounter a broad spectrum of antimicrobial compounds in their environments and often possess metabolic strategies to detoxify such xenobiotics. We have previously shown that Fusarium verticillioides, fungal pathogen maize known for its production fumonisin mycotoxins, possesses two unlinked loci, FDB1 FDB2, necessary detoxification produced by maize, including the γ-lactam 2-benzoxazolinone (BOA). In support these earlier studies, microarray analysis F. verticillioides exposed BOA...
Aim Determine the impact of beneficial phytochemicals on diversity and abundance gut microbiome in honey bee (Apis mellifera). Methods Results Eight-day-old workers were fed 25 ppm phytochemical (caffeine, gallic acid, p-coumaric acid or kaempferol) 20% sucrose. Guts bees collected at 3 6 days excised subjected to next-generation sequencing for bacterial 16S fungal ITS regions. Although supplementation fostered microbial abundance, patterns differed between there was a temporal stabilization...
ABSTRACT Fusarium species can cause severe root disease and damping-off in conifer nurseries. inoculum is commonly found most container bareroot nurseries on healthy diseased seedlings, nursery soils, seeds. Isolates of spp. differ virulence; however, virulence colony morphology are not correlated. Forty-one isolates spp., morphologically indistinguishable from F. oxysporum, were collected samples (soils, seedlings). These characterized by amplified fragment length polymorphism (AFLP) DNA...
Summary A rmillaria species display diverse ecological roles ranging from beneficial saprobe to virulent pathogen. solidipes (formerly . ostoyae ), a causal agent of root disease, is primary pathogen with broad host range woody plants across the N orthern H emisphere. This white‐rot grows between trees as rhizomorphs and attacks sapwood mycelial fans under bark. Armillaria disease responsible for reduced forest productivity due direct tree mortality non‐lethal infections that impact growth....
The Neonatal Intensive Care Unit (NICU) has a language and culture that is its own. For professionals, it place of intense constant attention to microdetails cautious optimism. parents, foreign with new unique culture. It also the setting in which they are introduced their child parenthood for this child. This combination been referred as an emotional cauldron. neonatal ethics literature mainly examines complex ethical dilemmas about withholding/drawing life sustaining interventions fragile...
Summary Fusarium species can cause damping‐off and root rot of young conifer seedlings, resulting in severe crop economic losses forest nurseries. Disease control within tree nurseries is difficult because the inability to characterize quantify spp. populations with regard disease potential high variability isolate virulence. isolates were collected from healthy diseased seedlings Douglas‐fir ( Pseudotsuga menziesii ) western white pine Pinus monticola a nursery Idaho, USA. Molecular markers...
Armillaria possesses several intriguing characteristics that have inspired wide interest in understanding phylogenetic relationships within and among species of this genus. Nuclear ribosomal DNA sequence-based analyses provide only limited information for studies widely divergent taxa. More recent shown translation elongation factor 1-α (tef1) sequences are highly informative analysis diverse global regions. This study used Neighbor-net coalescence-based Bayesian to examine newly determined...
Previous studies have shown that the members of Enterobacter cloacae complex are difficult to differentiate with biochemical tests and in phylogenetic using multilocus sequence analysis, strains same species separate into numerous clusters.There only a few complete E. genome sequences very little knowledge about mechanism pathogenesis on plants humans.Enterobacter EcWSU1 causes bulb decay stored onions (Allium cepa).The consists 4,734,438 bp chromosome mega-plasmid 63,653 bp.The has 4,632...
Fusarioid fungi that cause damping-off and root diseases can result in significant losses to conifer crops produced forest nurseries across the USA. These are vital reforestation restoration efforts. Understanding diversity of associated with seedlings provide an approach for targeted management techniques limit seedling pathogen spread novel landscapes.This study identifies 26 Fusarium spp. (F. acuminatum, F. annulatum, avenaceum, brachygibbosum, clavus, commune, cugenangense,...
