We report, for the first time, the occurrence of Paecilomyces niveus as an entomopathogen of the aphid Nasonovia ribisnigri in Pinhais, Paraná, Brazil. Samples of mummified aphids were collected from lettuce crops. The fungus P. niveus (PaePR) was isolated from the insect bodies and identified by macro and micromorphology. The species was confirmed by sequencing Internal Transcribed Spacer (ITS) rDNA. We obtained a sequence of 528 bp (accession number HQ441751), which aligned with Byssochlamys nivea strains (100% identities). In a bioassay, 120 h after inoculation of N. -

The function of spores is to disperse fungi to new areas and to get them through difficult periods. This Spores also makes them important vehicles for food contamination. Formation of spores is a complex process that is Conidia regulated by the cooperation of different transcription factors. The discussion of the biology of spore formation, Ascospores with the genus Aspergillus as an example, points to possible novel ways to eradicate fungal spore production in Nomenclature food. Fungi can produce different types of spores, sexual and asexually, within the same colony. The absence or Development Stress resistance presence of sexual spore formation has led to a dual nomenclature for fungi. Molecular techniques have led to a Heat-resistant fungi revision of this nomenclature. A number of fungal species form sexual spores, which are exceptionally stress- resistant and survive pasteurization and other treatments. A meta-analysis is provided of numerous D-values of heat-resistant ascospores generated during the years. The relevance of fungal spores for food microbiology has been discussed. 1.

The predominant species of Paecilomyces that had been identified was Paecilomyces variotii, the type species of the genus. Oatmeal Agar was used to induce the teleomorph at 37∞C.

Biocontrol Effects of Paecilomyces Variotii Against Fungal Plant Diseases
Journal of Fungi Article Biocontrol Effects of Paecilomyces variotii against Fungal Plant Diseases Alejandro Moreno-Gavíra, Fernando Diánez , Brenda Sánchez-Montesinos and Mila Santos * Departamento de Agronomía, Escuela Superior de Ingeniería, Universidad de Almería, 04120 Almería, Spain; [email protected] (A.M.-G.); [email protected] (F.D.); [email protected] (B.S.-M.) * Correspondence: [email protected]; Tel.: +34-950-015511 Abstract: The genus Paecilomyces is known for its potential application in the control of pests and diseases; however, its use in agriculture is limited to few species. Research interest in new formula- tions based on microorganisms for the control of pathogens is growing exponentially; therefore, it is necessary to study new isolates, which may help control diseases effectively, and to examine their compatibility with established agricultural control methods. We analysed in vitro and in vivo the antagonistic capacity of Paecilomyces variotii against seven phytopathogens with a high incidence in different crops, and we examined its compatibility with 24 commercial fungicides. P. variotii was applied in the following pathosystems: B. cinereal—melon, Sclerotinia sclerotiorum—pepper, R. solani— tomato, F. solani—zucchini, P. aphanidermatum—melon, M. melonis—melon, and P. xanthii—zucchini. The results showed strong control effects on M. melonis and P. xanthii, reducing the disease severity index by 78% and 76%, respectively. The reduction in disease severity in the other pathosystems ranged from 29% to 44%. However, application of metabolites alone did not cause any significant effect on mycelial growth of phytopathogens, apart from F. solani, in which up to 12% inhibition was Citation: Moreno-Gavíra, A.; Diánez, observed in vitro when the extract was applied at a concentration of 15% in the medium. -
A Taxonomic and Phylogenetic Investigation of Conifer Endophytes
A Taxonomic and Phylogenetic Investigation of Conifer Endophytes of Eastern Canada by Joey B. Tanney A thesis submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Biology Carleton University Ottawa, Ontario © 2016 Abstract Research interest in endophytic fungi has increased substantially, yet is the current research paradigm capable of addressing fundamental taxonomic questions? More than half of the ca. 30,000 endophyte sequences accessioned into GenBank are unidentified to the family rank and this disparity grows every year. The problems with identifying endophytes are a lack of taxonomically informative morphological characters in vitro and a paucity of relevant DNA reference sequences. A study involving ca. 2,600 Picea endophyte cultures from the Acadian Forest Region in Eastern Canada sought to address these taxonomic issues with a combined approach involving molecular methods, classical taxonomy, and field work. It was hypothesized that foliar endophytes have complex life histories involving saprotrophic reproductive stages associated with the host foliage, alternative host substrates, or alternate hosts. Based on inferences from phylogenetic data, new field collections or herbarium specimens were sought to connect unidentifiable endophytes with identifiable material. Approximately 40 endophytes were connected with identifiable material, which resulted in the description of four novel genera and 21 novel species and substantial progress in endophyte taxonomy. Endophytes were connected with saprotrophs and exhibited reproductive stages on non-foliar tissues or different hosts. These results provide support for the foraging ascomycete hypothesis, postulating that for some fungi endophytism is a secondary life history strategy that facilitates persistence and dispersal in the absence of a primary host.
