Biological pretreatment of rice husks with the white-rot fungus pleurotus ostreatus: the role of laccase activity
El objetivo principal de la investigación fue determinar la influencia de la composición del medio de cultivo y los compuestos lignocelulósicos en la secreción de enzimas lacasas por P. ostreatus en cultivos sumergidos. ... -
Characterization of transposon activity and genome-wide epigenetic regulation throughout the life cycle of Pleurotus ostreatus
Most prokaryotic and eukaryotic life forms have to deal with the presence of repetitive DNA sequences called transposable elements (TEs), whose ability to mobilize through the genome and insert at random position has an ... -
Comparative and transcriptional analysis of the predicted secretome in the lignocellulose-degrading basidiomycete fungus Pleurotus ostreatus
Fungi interact with their environment by secreting proteins to obtain nutrients, elicit responses and modify their surroundings. Because the set of proteins secreted by a fungus is related to its lifestyle, it should be ... -
Computational prediction of protein-coding gene and annotation of DNA sequences with agronomic interest in Pleurotus ostreatus (Oyster Mushroom)
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2006) Contribución a congreso / Biltzarrerako ekarpenaPleurotus ostreatus, commonly known as oyster mushroom, is a commercially important edible fungus with interesting biotechnological properties. Quantitative trait loci (QTL) analyses are rare in fungi and little is known ... -
Efecto de la inducción con extractos acuosos de paja de trigo sobre la producción de enzimas lignolíticas en Pleurotus Ostreatus
En la producción de energía a partir de materiales lignocelulósicos, el pretratamiento termoquímico se realiza para desestructurar la lignocelulosa y facilitar la acción posterior de enzimas celulolíticas (endoglucanasas, ... -
Estudio de la variación en los niveles de transcripción de genes de enzimas degradadoras de lignina en cultivos sólidos y sumergidos de Pleurotus ostreatus
La lignocelulosa es el componente principal de la madera y de los residuos vegetales, lo que supone la mayor cantidad de biomasa de la tierra. La lignina es un polímero heterogéneo recalcitrante a la degradación química ... -
Expresión génica de peroxidasas ligninolíticas en Pleurotus ostreatus: regulación por temperatura y pH
Pleurotus ostreatus es un hongo comestible de gran importancia biotecnológica por ser un organismo modelo degradador de lignina. Su genoma contiene nueve genes codificantes de peroxidasas ligninolíticas, características ... -
Genetic linkage map of the edible basidiomycete Pleurotus ostreatus
We have constructed a genetic linkage map of the edible basidiomycete Pleurotus ostreatus (var. Florida). The map is based on the segregation of 178 random amplified polymorphic DNA and 23 restriction fragment length polymorphism ... -
Genomic, transcriptomic and proteomic analysis of Pleurotus ostreatus secreted proteins
The objective of this thesis is to study the proteins secreted by the edible and worldwide cultivated white rot basidiomycete fungus Pleurotus ostreatus with three major goals: to determine the set of proteins secreted ... -
Genomics and transcriptomics characterization of genes expressed during postharvest at 4 degrees C by the edible basidiomycete Pleurotus ostreatus
Pleurotus ostreatus is an industrially cultivated basidiomycete with nutritional and environmental applications. Its genome, which was sequenced by the joint Genome Institute, has become a model for lignin degradation ... -
Highly expressed captured genes and cross-kingdom domains present in Helitrons create novel diversity in Pleurotus ostreatus and other fungi
Background: Helitrons are class-II eukaryotic transposons that transpose via a rolling circle mechanism. Due to their ability to capture and mobilize gene fragments, they play an important role in the evolution of their ... -
Identification and functional characterisation of ctr1, a Pleurotus ostreatus gene coding for a copper transporter
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2006) Contribución a congreso / Biltzarrerako ekarpenaCopper homeostasis is primordial for life maintenance and especially relevant for ligning-degrading fungi whose phenol-oxidase enzymes depend on this micronutrient for their activity. In this paper we report the ... -
Ligninolytic peroxidase gene expression by Pleurotus ostreatus: differential regulation in lignocellulose medium and effect of temperature and pH
Pleurotus ostreatus is an important edible mushroom and a model lignin degrading organism, whose genome contains nine genes of ligninolytic peroxidases, characteristic of white-rot fungi. These genes encode six manganese ... -
