Abstract

BackgroundThe fungal genus Aspergillus is of critical importance to humankind. Species include those with industrial applications, important pathogens of humans, animals and crops, a source of potent carcinogenic contaminants of food, and an important genetic model. The genome sequences of eight aspergilli have already been explored to investigate aspects of fungal biology, raising questions about evolution and specialization within this genus.ResultsWe have generated genome sequences for ten novel, highly diverse Aspergillus species and compared these in detail to sister and more distant genera. Comparative studies of key aspects of fungal biology, including primary and secondary metabolism, stress response, biomass degradation, and signal transduction, revealed both conservation and diversity among the species. Observed genomic differences were validated with experimental studies. This revealed several highlights, such as the potential for sex in asexual species, organic acid production genes being a key feature of black aspergilli, alternative approaches for degrading plant biomass, and indications for the genetic basis of stress response. A genome-wide phylogenetic analysis demonstrated in detail the relationship of the newly genome sequenced species with other aspergilli.ConclusionsMany aspects of biological differences between fungal species cannot be explained by current knowledge obtained from genome sequences. The comparative genomics and experimental study, presented here, allows for the first time a genus-wide view of the biological diversity of the aspergilli and in many, but not all, cases linked genome differences to phenotype. Insights gained could be exploited for biotechnological and medical applications of fungi.

Abstract

Plants and fungi use light and other signals to regulate development, growth, and metabolism. The fruiting bodies of the fungus Phycomyces blakesleeanus are single cells that react to environmental cues, including light, but the mechanisms are largely unknown [1]. The related fungus Mucor circinelloides is an opportunistic human pathogen that changes its mode of growth upon receipt of signals from the environment to facilitate pathogenesis [2]. Understanding how these organisms respond to environmental cues should provide insights into the mechanisms of sensory perception and signal transduction by a single eukaryotic cell, and their role in pathogenesis. We sequenced the genomes of P. blakesleeanus and M. circinelloides and show that they have been shaped by an extensive genome duplication or, most likely, a whole-genome duplication (WGD), which is rarely observed in fungi [3-6]. We show that the genome duplication has expanded gene families, including those involved in signal transduction, and that duplicated genes have specialized, as evidenced by differences in their regulation by light. The transcriptional response to light varies with the developmental stage and is still observed in a photoreceptor mutant of P. blakesleeanus. A phototropic mutant of P. blakesleeanus with a heterozygous mutation in the photoreceptor gene madA demonstrates that photosensor dosage is important for the magnitude of signal transduction. We conclude that the genome duplication provided the means to improve signal transduction for enhanced perception of environmental signals. Our results will help to understand the role of genome dynamics in the evolution of sensory perception in eukaryotes.

Abstract

Results show that although mutation in the wide-domain repressor CreA gene leads to an elevated levels of xlnB mRNA, none of the CreA consensus target sites are localized in the xlnB gene. Data suggest that the catabolite repression of the xlnB encoded xylanase is exerted in an indirect manner.

Abstract

Protoplast transformation for the introduction of recombinant DNA into Aspergillus nidulans is technically demanding and dependant on the availability and batch variability of commercial enzyme preparations. Given the success of Agrobacterium tumefaciens-mediated transformation (ATMT) in diverse pathogenic fungi, we have adapted this method to facilitate transformation of A. nidulans. Using suitably engineered binary vectors, gene-targeted ATMT of A. nidulans non-homologous end-joining (NHEJ) mutant conidia has been carried out for the first time by complementation of a nutritional requirement (uridine/uracil auxotrophy). Site-specific integration in the DnkuA host genome occurred at high efficiency. Unlike other transformation techniques, however, cross-feeding of certain nutritional requirements from the bacterium to the fungus was found to occur, thus limiting the choice of auxotrophies available for ATMT. In complementation tests and also for comparative purposes, integration of recombinant cassettes at a specific locus could provide a means to reduce the influence of position effects (chromatin structure) on transgene expression. In this regard, targeted disruption of the wA locus permitted visual identification of transformants carrying site-specific integration events by conidial colour (white), even when auxotrophy selection was compromised due to cross-feeding. The protocol described offers an attractive alternative to the protoplast procedure for obtaining locus-targeted A. nidulans transformants. [ABSTRACT FROM AUTHOR]

Abstract

Abstract Background Little is known about the structure and regulation of fungal α-L-rhamnosidase genes despite increasing interest in the biotechnological potential of the enzymes that they encode. Whilst the paradigmatic filamentous fungus Aspergillus nidulans growing on L-rhamnose produces an α-L-rhamnosidase suitable for oenological applications, at least eight genes encoding putative α-L-rhamnosidases have been found in its genome. In the current work we have identified the gene (rhaE) encoding the former activity, and characterization of its expression has revealed a novel regulatory mechanism. A shared pattern of expression has also been observed for a second α-L-rhamnosidase gene, (AN10277/rhaA). Results Amino acid sequence data for the oenological α-L-rhamnosidase were determined using MALDI-TOF mass spectrometry and correspond to the amino acid sequence deduced from AN7151 (rhaE). The cDNA of rhaE was expressed in Saccharomyces cerevisiae and yielded pNP-rhamnohydrolase activity. Phylogenetic analysis has revealed this eukaryotic α-L-rhamnosidase to be the first such enzyme found to be more closely related to bacterial rhamnosidases than other α-L-rhamnosidases of fungal origin. Northern analyses of diverse A. nidulans strains cultivated under different growth conditions indicate that rhaA and rhaE are induced by L-rhamnose and repressed by D-glucose as well as other carbon sources, some of which are considered to be non-repressive growth substrates. Interestingly, the transcriptional repression is independent of the wide domain carbon catabolite repressor CreA. Gene induction and glucose repression of these rha genes correlate with the uptake, or lack of it, of the inducing carbon source L-rhamnose, suggesting a prominent role for inducer exclusion in repression. Conclusions The A. nidulans rhaE gene encodes an α-L-rhamnosidase phylogenetically distant to those described in filamentous fungi, and its expression is regulated by a novel CreA-independent mechanism. The identification of rhaE and the characterization of its regulation will facilitate the design of strategies to overproduce the encoded enzyme - or homologs from other fungi - for industrial applications. Moreover, A. nidulans α-L-rhamnosidase encoding genes could serve as prototypes for fungal genes coding for plant cell wall degrading enzymes regulated by a novel mechanism of CCR.

29. Transcriptional analysis of the lichenase-like gene cel12Aof the filamentous fungus Stachybotrys atraBP-A and its relevance for lignocellulose depolymerization

Author

Abstract

To rationally optimize the production of industrial enzymes by molecular means requires previous knowledge of the regulatory circuits controlling the expression of the corresponding genes. The genus Stachybotrysis an outstanding producer of cellulose-degrading enzymes. Previous studies isolated and characterized the lichenase-like/non-typical cellulase Cel12A of S. atra(AKA S. chartarum) belonging to glycosyl hydrolase family 12 (GH12). In this study, we used RT-qPCR to determine the pattern of expression of cel12Aunder different carbon sources and initial ambient pH. Among the carbon sources examined, rice straw triggered a greater increase in the expression of cel12Athan 1% lactose or 0.1% glucose, indicating specific induction by rice straw. In contrast, cel12Awas repressed in the presence of glucose even when combined with this inducer. The proximity of 2 adjacent 5′-CTGGGGTCTGGGG-3′ CreA consensus target sites to the translational start site of cel12Astrongly suggests that the carbon catabolite repression observed is directly mediated by CreA. Ambient pH did not have a significant effect on cel12Aexpression. These findings present new knowledge on transcriptional regulatory networks in Stachybotrysassociated with cellulose/hemicellulose depolymerization. Rational engineering of CreA to remove CCR could constitute a novel strategy for improving the production of Cel12A.

Abstract

Plants and fungi use light and other signals to regulate development, growth, and metabolism. The fruiting bodies of the fungus Phycomyces blakesleeanus are single cells that react to environmental cues, including light, but the mechanisms are largely unknown [1]. The related fungus Mucor circinelloides is an opportunistic human pathogen that changes its mode of growth upon receipt of signals from the environment to facilitate pathogenesis [2]. Understanding how these organisms respond to environmental cues should provide insights into the mechanisms of sensory perception and signal transduction by a single eukaryotic cell, and their role in pathogenesis. We sequenced the genomes of P. blakesleeanus and M. circinelloides and show that they have been shaped by an extensive genome duplication or, most likely, a whole-genome duplication (WGD), which is rarely observed in fungi [3, 4, 5, 6]. We show that the genome duplication has expanded gene families, including those involved in signal transduction, and that duplicated genes have specialized, as evidenced by differences in their regulation by light. The transcriptional response to light varies with the developmental stage and is still observed in a photoreceptor mutant of P. blakesleeanus. A phototropic mutant of P. blakesleeanus with a heterozygous mutation in the photoreceptor gene madA demonstrates that photosensor dosage is important for the magnitude of signal transduction. We conclude that the genome duplication provided the means to improve signal transduction for enhanced perception of environmental signals. Our results will help to understand the role of genome dynamics in the evolution of sensory perception in eukaryotes.

Abstract

La OTRI del Centro Tecnológico Nacional de la Conserva y Alimentación junto con la OTT del Consejo Superior de Investigaciones Científicas, colaboran en el Proyecto AGROCSIC, el cual fue aprobado por el Ministerio de Ciencia y Tecnología y financiado por el Ministerio de Educación y Ciencia. El objetivo principal de esta nueva actuación es estudiar las distintas líneas de trabajo de los Centros del CSIC relacionadas con la alimentación, para transferir sus resultados al sector industrial., Desde el punto de vista microbiológico, la transformación del mosto de uva en vino o vinificación es un proceso complejo en el que intervienen distintos microorganismos, y donde las levaduras, principalmente Saccharomyces cerevisiae, juegan el papel más destacado. Durante la vinificación las levaduras utilizan los azúcares y otros componentes del mosto para su crecimiento, produciendo etanol, anhídrido carbónico, y en menor medida otros compuestos responsables de la composición química y las cualidades sensoriales del vino. Desde un punto de vista bioquímico, el vino puede considerarse como un producto de la transformación enzimática del mosto de uva., En las últimas décadas, coincidiendo con el avance de la Biotecnología, se han desarrollado nuevas técnicas de vinificación, que incluyen, entre otras, la utilización de cepas seleccionadas de S. cerevisiae (para normalizar la microbiota inicial y dar lugar a fermentaciones homogéneas año tras año), y el empleo de enzimas (para solucionar problemas puntuales del proceso y mejorar la calidad del producto final). El uso de levaduras seleccionadas, capaces de conducir la fermentación alcohólica e imponerse al resto de levaduras presentes, abre la posibilidad de aplicar técnicas de ingeniería genética a la levadura vínica para obtener nuevas cepas capaces de producir, a lo largo de la fermentación, las enzimas de interés en enología cuya adición se realiza de forma regular. Asimismo, las técnicas de ADN recombinante se están aplicando a la vid, donde se están produciendo importantes avances (como por ejemplo la producción de plantas resistentes a ciertas enfermedades víricas y fúngicas) y a los microorganismos productores de los preparados enzimáticos comerciales de uso en enología (por ejemplo para conseguir mayores rendimientos y preparados más específicos)., La información que las autoras aportan a esta revisión es fruto del desarrollo de varios proyectos financiados por la Comisión Interministerial de Ciencia y Tecnología (CICYT) entre los que se incluyen los proyectos en curso AGL2002-01906, AGL2003-01295/ALI y AGL2004-00978/ALI.
