  • Genome Sequencing and Analysis of Talaromyces Pinophilus Provide
    www.nature.com/scientificreports OPEN Genome sequencing and analysis of Talaromyces pinophilus provide insights into biotechnological Received: 4 October 2016 Accepted: 3 March 2017 applications Published: xx xx xxxx Cheng-Xi Li, Shuai Zhao, Ting Zhang, Liang Xian, Lu-Sheng Liao, Jun-Liang Liu & Jia-Xun Feng Species from the genus Talaromyces produce useful biomass-degrading enzymes and secondary metabolites. However, these enzymes and secondary metabolites are still poorly understood and have not been explored in depth because of a lack of comprehensive genetic information. Here, we report a 36.51-megabase genome assembly of Talaromyces pinophilus strain 1–95, with coverage of nine scaffolds of eight chromosomes with telomeric repeats at their ends and circular mitochondrial DNA. In total, 13,472 protein-coding genes were predicted. Of these, 803 were annotated to encode enzymes that act on carbohydrates, including 39 cellulose-degrading and 24 starch-degrading enzymes. In addition, 68 secondary metabolism gene clusters were identified, mainly including T1 polyketide synthase genes and nonribosomal peptide synthase genes. Comparative genomic analyses revealed that T. pinophilus 1–95 harbors more biomass-degrading enzymes and secondary metabolites than other related filamentous fungi. The prediction of theT. pinophilus 1–95 secretome indicated that approximately 50% of the biomass-degrading enzymes are secreted into the extracellular environment. These results expanded our genetic knowledge of the biomass-degrading enzyme system of T. pinophilus and its biosynthesis of secondary metabolites, facilitating the cultivation of T. pinophilus for high production of useful products. Talaromyces pinophilus, formerly designated Penicillium pinophilum, is a fungus that produces biomass-degrading enzymes such as α-amylase1, cellulase2, endoglucanase3, xylanase2, laccase4 and α-galactosidase2.

  • New Xerophilic Species of Penicillium from Soil
    Journal of Fungi Article New Xerophilic Species of Penicillium from Soil Ernesto Rodríguez-Andrade, Alberto M. Stchigel * and José F. Cano-Lira Mycology Unit, Medical School and IISPV, Universitat Rovira i Virgili (URV), Sant Llorenç 21, Reus, 43201 Tarragona, Spain; [email protected] (E.R.-A.); [email protected] (J.F.C.-L.) * Correspondence: [email protected]; Tel.: +34-977-75-9341 Abstract: Soil is one of the main reservoirs of fungi. The aim of this study was to study the richness of ascomycetes in a set of soil samples from Mexico and Spain. Fungi were isolated after 2% w/v phenol treatment of samples. In that way, several strains of the genus Penicillium were recovered. A phylogenetic analysis based on internal transcribed spacer (ITS), beta-tubulin (BenA), calmodulin (CaM), and RNA polymerase II subunit 2 gene (rpb2) sequences showed that four of these strains had not been described before. Penicillium melanosporum produces monoverticillate conidiophores and brownish conidia covered by an ornate brown sheath. Penicillium michoacanense and Penicillium siccitolerans produce sclerotia, and their asexual morph is similar to species in the section Aspergilloides (despite all of them pertaining to section Lanata-Divaricata). P. michoacanense differs from P. siccitol- erans in having thick-walled peridial cells (thin-walled in P. siccitolerans). Penicillium sexuale differs from Penicillium cryptum in the section Crypta because it does not produce an asexual morph. Its ascostromata have a peridium composed of thick-walled polygonal cells, and its ascospores are broadly lenticular with two equatorial ridges widely separated by a furrow. All four new species are xerophilic.

    SEM2, CC4, Unit 3 Ascomycota: Life cycle of Saccharomyces, Talaromyces (Penicillium), Neurospora and Ascobolus Dr. Subhadip Chakraborty Life cycle of Talaromyces: Pathogenic fungi have evolved traits that allow them to infect and grow on or in a host. One such trait is the ability to alternate growth forms, where each is suited to a particular environment. This ability is called dimorphism, and it is exhibited by a diverse group of pathogenic fungi (Fig. 1). P. marneffei is an emerging human-pathogenic fungus endemic to Southeast Asia, where it is considered to be AIDS defining. P. marneffei infections occur primarily in individuals with defined immunocompromising conditions; however, a small number of cases of infection in patients without a diagnosed immunodeficiency have also been reported (1, 2). In none of the latter cases has immunocompetency been demonstrated. P. marneffei lacks a defined sexual cycle but possesses all of the genes believed to be required for mating, including both mating type idiomorphs in a heterothallic arrangement among isolates (3). P. marneffei, like a number of other fungal pathogens, exhibits temperature-dependent dimorphic growth, hyphal at 25°C and yeast at 37°C. Exposure to an air interface at 25°C promotes the saprophytic hyphae to differentiate to produce asexual spores (conidia), the infectious agents (Fig. 2). Conidia inhaled into the host lung are phagocytosed by pulmonary alveolar macrophages. Within macrophages, conidia germinate into unicellular yeast cells, which divide by fission (4). This minireview focuses on the current understanding of the genes required for the morphogenetic control of conidial germination, hyphal growth, asexual development, and yeast morphogenesis in P.
