Abstract:
Living organisms are part of a highly interconnected web of interactions, characterised by species nurturing, competing, parasitizing and preying on one another. Plants have evolved cooperative as well as defensive strategies to interact with neighbour organisms. Among these, the plant-fungus associations are very diverse, ranging from pathogenic to mutualistic. Our current knowledge of plant-fungus interactions suggests a sophisticated coevolution to ensure dynamic plant responses to evolving fungal mutualistic/pathogenic strategies. The plant-fungus communication relies on a rich chemical language. To manipulate the plant defence mechanisms, fungi produce and secrete several classes of biomolecules, whose modeof- action is largely unknown. Upon perception of the fungi, plants produce phytohormones and a battery of secondary metabolites that serve as defence mechanism against invaders or to promote mutualistic associations. These mutualistic chemical signals can be co-opted by pathogenic fungi for their own benefit. Among the plant molecules regulating plant-fungus interaction, phytohormones play a critical role since they modulate various aspects of plant development, defences and stress responses. Intriguingly, fungi can also produce phytohormones, although the actual role of fungalproduced phytohormones in plant-fungus interactions is poorly understood. Here, we discuss the recent advances in fungal production of phytohormone, their putative role as endogenous fungal signals and how fungi manipulate plant hormone balance to their benefits.

Abstract:
ABSTRACTThe histidine phosphotransfer (HPt) protein Ypd1 is an important participant in theSaccharomyces cerevisiaemultistep two-component signal transduction pathway and, unlike the expanded histidine kinase gene family, is encoded by a single gene in nearly all model and pathogenic fungi. Ypd1 is essential for viability in bothS. cerevisiaeand inCryptococcus neoformans. These and other aspects of Ypd1 biology, combined with the availability of structural and mutational data inS. cerevisiae, suggest that the essential interactions between Ypd1 and response regulator domains would be a good target for antifungal drug development. The goal of this minireview is to summarize the wealth of data onS. cerevisiaeYpd1 and to consider the potential benefits of conducting related studies in pathogenic fungi.

Abstract:
The corn smut fungus Ustilago maydis serves as a model species for studying fungal dimorphism and its role in phytopathogenic development. The pathogen has two growth phases: a saprobic yeast phase and a pathogenic filamentous phase. Dimorphic transition of U. maydis involves complex processes of signal perception, mating, and cellular reprogramming. Recent advances in improvement of reference genomes, high-throughput sequencing and molecular genetics studies have been expanding research in this field. However, the biology of other non-model species is frequently overlooked. This leads to uncertainty regarding how much of what is known in U. maydis is applicable to other dimorphic fungi. In this review, we will discuss dimorphic fungi in the aspects of physiology, reproductive biology, genomics, and molecular genetics. We also perform comparative analyses between U. maydis and other fungi in Ustilaginomycotina, the subphylum to which U. maydis belongs. We find that lipid/hydrophobicity is a potential common cue for dimorphic transition in plant-associated dimorphic fungi. However, genomic profiles alone are not adequate to explain dimorphism across different fungi.

Abstract:
ABSTRACTFungi are exposed to broadly fluctuating environmental conditions, to which adaptation is crucial for their survival. An ability to respond to a wide pH range, in particular, allows them to cope with rapid changes in their extracellular settings. PacC/Rim signaling elicits the primary pH response in both model and pathogenic fungi and has been studied in multiple fungal species. In the predominant human pathogenic fungi, namely,Candida albicans,Aspergillus fumigatus, andCryptococcus neoformans, this pathway is required for many functions associated with pathogenesis and virulence. Aspects of this pathway are fungus specific and do not exist in mammalian cells. In this review, we highlight recent advances in our understanding of PacC/Rim-mediated functions and discuss the growing interest in this cascade and its factors as potential drug targets for antifungal strategies. We focus on both conserved and distinctive features in model and pathogenic fungi, highlighting the specificities of PacC/Rim signaling inC. albicans,A. fumigatus, andC. neoformans. We consider the role of this pathway in fungal virulence, including modulation of the host immune response. Finally, as now recognized for other signaling cascades, we highlight the role of pH in adaptation to antifungal drug pressure. By acting on the PacC/Rim pathway, it may therefore be possible (i) to ensure fungal specificity and to limit the side effects of drugs, (ii) to ensure broad-spectrum efficacy, (iii) to attenuate fungal virulence, (iv) to obtain additive or synergistic effects with existing antifungal drugs through tolerance inhibition, and (v) to slow the emergence of resistant mutants.

Abstract:
AbstractEndo- and exo-polygalacturonases produced by various fungi are involved in the degradation of pectic substances. They have found a wide range of applications in the food and textile industries. Several phyto-pathogenic fungi secrete polygalacturonases and they act as virulence factors during plant pathogenesis. The comparison of biochemical properties of different fungal polygalacturonases, their mechanism of actions, structural aspects and interactions with inhibitors/proteins could be used as a possible strategy for the fungal-crop disease management. This review focuses on fungal polygalacturonases, including their regulation, comparative biochemical and structural characterizations and their interactions with inhibitors.

Abstract:
Heterobimetallic complexes with varying amines have been synthesized by the reaction of [Pt(C2H8N2)2]Cl2 with group four or fourteen organometallic dichlorides, viz., R2MCl2 and Cp2M'Cl2 in a 1:2 molar ratio in MeOH (where M=Si or Sn, M'= Ti or Zr and R=Ph or Me). These complexes have been characterized by elemental analysis, molecular weight determinations, magnetic measurements, conductance, IR, H1 NMR and electronic spectra. The spectral data suggest a square planar geometry for all the complexes. Conductivity data suggest that they behave as electrolytes. These monometallic precursors along with their complexes have been screened in vitro against a number of pathogenic fungi and bacteria to assess their growth inhibiting potential.

Abstract:
Airborne opportunistic fungi, includingAspergillusand other less common saprophytic molds, have recently emerged as important causes of mortality in immunocompromised individuals. Understanding the molecular mechanisms of host-fungal interplay in robust experimental pathosystems is becoming a research priority for development of novel therapeutics to combat these devastating infections. Over the past decade, invertebrate hosts with evolutionarily conserved innate immune signaling pathways and powerful genetics, such asDrosophila melanogaster, have been employed as a means to overcome logistic restrains associated with the use mammalian models of fungal infections. Recent studies inDrosophilamodels of filamentous fungi demonstrated that several genes implicated in fungal virulence in mammals also play a similarly important pathogenic role in fruit flies, and important host-related aspects in fungal pathogenesis are evolutionarily conserved. In view of recent advances inDrosophilagenetics, fruit flies will become an invaluable surrogate model to study immunopathogenesis of fungal diseases.

Abstract:
The dimorphic fungi of the Paracoccidioides genus are the causative agents of paracoccidioidomycosis (PCM). This disease is endemic in Latin America and primarily affects workers in rural areas. PCM is considered a neglected disease, despite being a disabling disease that has a notable impact on the public health system. Paracoccidioides spp. are thermally dimorphic fungi that present infective mycelia at 25 °C and differentiate into pathogenic yeast forms at 37 °C. This transition involves a series of morphological, structural, and metabolic changes which are essential for their survival inside hosts. As a pathogen, the fungus is subjected to several varieties of stress conditions, including the host immune response, which involves the production of reactive nitrogen and oxygen species, thermal stress due to temperature changes during the transition, pH alterations within phagolysosomes, and hypoxia inside granulomas. Over the years, studies focusing on understanding the establishment and development of PCM have been conducted with several limitations due to the low effectiveness of strategies for the genetic manipulation of Paracoccidioides spp. This review describes the most relevant biological features of Paracoccidioides spp., including aspects of the phylogeny, ecology, stress response, infection, and evasion mechanisms of the fungus. We also discuss the genetic aspects and difficulties of fungal manipulation, and, finally, describe the advances in molecular biology that may be employed in molecular research on this fungus in the future.

Abstract:
Synthetic, spectroscopic and antimicrobial aspects of some fertility inhibitor heterobimetallic complexes have been carried out. These heterobimetallic chelates [M(C5H5N3)2M2'(R)4]Cl2 (M = Pd or Pt and M' = Si, Sn, Ti and Zr) have been successfully synthesinzed via the reaction of M(C5H7N3)2Cl2 with group four or fourteen dichlorides in 1:2 stoichiometric proportions. The products were characterized by elemental analyses, molecular weight determinations, magnetic susceptibility measurements, conductance, and IR multinuclear NMR and electronic spectral studies. A square planar geometry has been suggested for all the complexes with the help of spectral data. Conductivity data strongly suggest that chlorine atoms are ionic in nature due to which complexes behave as electrolytes. All the complexes have been evaluated for their antmicrobial effects on different species of pathogenic fungi and bacteria. The testicular sperm density, testicular sperm morphology, sperm motility, density of cauda epididymal spermatozoa and fertility in mating trails and biochemical parameters of reproductive organs have been examined and discussed.

Abstract:
The results of studies about interactions between microorganisms involving at least one plant pathogen are of interest to the areas of ethiology and control in Plant Pathology. Various aspects of these interactions have been studied over the years but the toxicity of volatile organic compounds (VOCs) has been emphasized only recently, developing techniques and procedures, and producing additional knowledge to those already obtained with water-soluble substances. This new facet of these interactions based on VOCs is discussed in this review involving mainly fungi, bacteria and nematodes pathogenic to plants. Also discussed is the role of VOCs produced by microorganisms, especially fungi and bacteria, in soil fungistasis and the effect of VOCs on fungal agents used in the control of plant parasitic nematodes. The evidence of VOCs broadens the research studies about these interactions. However, the scarcity of the research results in this area show up gaps which need to be filled and some research proposals are discussed. The present and future accumulated VOC knowledge will perhaps be beneficial to farmers, especially aspects related to increasing soil suppressiveness to plant disease and to the finding of analog molecules of VOCs highly effective against plant pathogens.

Abstract:
A antracnose é uma das principais doenças que afetam a goiaba no Estado de São Paulo. Tanto Colletotrichum gloeosporioides quanto Colletotrichum acutatum, são relatados como sendo os agentes causais da doença. Os objetivos do trabalho foram caracterizar e identificar 54 isolados de Colletotrichum oriundos de lesões de goiaba, baseados nos aspectos culturais, morfológicos, moleculares e enzimáticos, além da caracterização patogênica de isolados representativos de cada espécie de Colletotrichum identificadas. A caracterização cultural foi avaliada mediante a mensuração do crescimento micelial dos isolados a 25 ºC, além dos aspectos culturais, como a coloração e a topografia das colônias. Na caracterização morfológica foram mensurados comprimento e largura de conídios, bem como avaliados os seus formatos. Oligonucleotídeos específicos foram utilizados na caracterização molecular, visando identificar as espécies dos isolados de Colletotrichum. A caracterização enzimática envolveu a mensuração, in vitro, do halo de degradação dos substratos da amilase, proteinase, celulase, pectinase e lipase. Por fim, alguns isolados representativos e identificados foram utilizados na caracterização patogênica, sendo avaliados os períodos de latência e incubação, a área lesionadas dos frutos e a esporulação. Baseados na coloração das colônias, os isolados foram reunidos em 9 grupos diferentes. Os mesmos puderam se reunidos em dois grupos distintos de acordo com a taxa do crescimento micelial. Os conídios apresentaram os formatos: (i) reto, fusiforme, com ápices afilados, (ii) reto, oblongo, com ápices arredondados, (iii) reto, clavado, afilado em uma extremidade e (iv) reto, com constrição. As dimensões variaram de 11,4 a 16,8 µm de comprimento por 2,6 a 4,9 µm de largura. O uso de oligonucleotídeos específicos permitiu identificar C. acutatum e C. gloeosporioides entre os isolados avaliados. Grande parte dos isolados, 94%, foram identificados como pertencendo à espécie C. gloeosporioides, enquanto que apenas 4% foram identificados como C. acutatum. Em relação à caracterização enzimática, apenas a atividade celulolítica proporcionou diferenças significativas entre C. gloeosporioides e C. acutatum. A patogenicidade dos isolados avaliados mostrou alta variabilidade na severidade da doença nos frutos, contudo não foi possível evidenciar diferenças significativas que distinguissem C. acutatum de C. gloeosporioides. Os períodos de incubação e latência foram menores para os isolados de C. acutatum em relação aos isolados de C. gloeosporioides. C. acutatum produziu quantidade superior de esporos nos frutos inoculados quando comparados a C. gloeosporioides. Observou-se, ainda, correlação positiva entre a área do halo de degradação de pectina, lipídio e amido e a área lesionada dos frutos afetados pelos isolados avaliados.
Anthracnose is one of the major diseases affecting guava in the State of São Paulo. Both Colletotrichum gloeosporioides and Colletotrichum acutatum are reported as the causal agents of the disease. The objectives of this work were to characterize and to identify 54 Colletotrichum isolates from guava, based on cultural, morphological, molecular, enzymatic, and pathogenic aspects. Cultural characterization was achieved by measuring the mycelial growth at 25 ° C, as well as reporting cultural aspects, such as color and topography of the colonies. In the morphological characterization it was measured length and width of conidia, and rated their shapes. CaInt2 and CgInt specific primers were used in the molecular identification of the Colletotrichum isolates. The enzymatic characterization was performed by measuring, in vitro degradation of starch, protein, cellulose, pectin and lipid. Finally some representative and identified isolates were used in the pathogenic characterization, evaluated by latency and incubation periods, diseased area and sporulation. Based on the color of the colonies, the isolates were grouped in 9 different groups. These same isolates showed two distinct growth paterns according to the mycelial growth rates. Conidia showed shapes: (i) straight, fusiform, with acute ends, (ii) straight, oblong, with round ends, (iii) straight, clavate, tapered at one end and (iv) straight, with a constriction in the middle. Conidia size ranged from 11.4 to 16.8 µm in length by 2.6 to 4.9 µm in width. The use of specific primers identified C. acutatum and C. gloeosporioides among the isolates. Most of the isolates (94%) were identified as C. gloeosporioides, while only (6%) were identified as C. acutatum. In the enzymatic characterization, only cellulolytic activity revealed significant differences between C. gloeosporioides and C. acutatum. Pathogenicity of the isolates was highly variable, but could not help to distinguish between C. acutatum and C. gloeosporioides. The incubation and latency periods were shorter for C. acutatum in relation to C. gloeosporioides. C. acutatum produced higher amounts of spores on inoculated fruits compared to C. gloeosporioides. There was also a positive correlation between in vitro degradation of pectin, lipid and starch, and the diseased area for tested isolates.

The virulence of the species of the entomopathogenic fungi Lecanicillium psalliotae (strain Vl 78), L. dimorphum (Vl 79) and L. pissodis (ARSEF 8057) against bean aphid Megoura viciae Buckt and greenhouse whitefly Trialeurodes vaporariorum Westwood has been compared with the virulence of well-studied species L. muscarium (Vl 21, Vl 72), L. lecanii (Vl 5), L. longisporum (Vl 13). Species L. longisporum (Vl 13), L. muscarium (Vl 72), L. psalliotae (Vl 78) had a virulence of more than 80% against bean aphid, other strains showed the virulence less than 60%. All strains except L. longisporum (Vl 13) had a high virulence about 75–100% against the greenhouse whitefly. As appeared, the species L. psalliotae (Vl 78) has the perspectives against the both insect species. Its virulence corresponds to the similar level of mortality caused by the well-studied species L. muscarium.

Abstract:
Molecular phylogeny of entomopathogenic fungi Metarhizium, Beauveria (199 Isolates) from different biocenoses of two climatic zones of the Novosibirsk Region (Western Siberia) was conducted using translation elongation factor gene (EF1a) sequence. Three species of Metarhizium and two species of Beauveria were identified: M. robertsii (54 isolates) M. brunneum (35 isolates) and M. pemphigum (2 isolates) B. bassiana (19 isolates) and B. pseudobassiana (9 isolates). Analisys of spatial distribution showed that M. robertsii preferred more xerophile habitats compared to M. brunneum. Moreover, genetic groups with different habitat association were revealed within M. robertsii. There are no differences in habitat association were registered for Beauveria species.

Abstract:
The paper refers to a composition with antifungal and antibacterial effect in order to test new materials for preserving heritage objects on collagen support with bactericidal/antifungal role, essential oils-based from Vetrice (Tanacetum vulgare, Compositae family), having antifungal and antibacterial properties. The biocidal effect of plant extracts is due to the presence of constituent agents, such as alcohols, ethers, phenols, aldehydes, ketones, which makes them extremely effective against a wide range of microbial strains. The essential oil was obtained by boiling the plants through continuous hydrodistillation with Clevenger refrigerant. The testing of the antimicrobial efficiency of the plant extracts was performed on two strains of pathogenic fungi, respectively Trichophyton interdigitale and Epidermophyton floccosum. The microbial inoculum was mixed with the plant extract from various sources (leaves, flowers and mixed flower-leaves). All extracts were tested in duplicate according to the specific test standards, and the results were expressed as a mean percentage and logarithmic reduction between the readings on the two Petri plates corresponding to each sample. To quantify the antimicrobial efficacy, the degree of microbial and logarithmic reduction of each sample was calculated, relative to the initial cell concentration. The results of antimicrobial tests showed a high antifungal character of the extracts obtained from flowers, leaves and mixed flower-leaves.
