Heterologous expression of mating type genes in basidiomycetes
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2006) Contribución a congreso / Biltzarrerako ekarpenaMating type genes in basidiomycetes encode two types of transcription factors (HD1 and HD2) and pheromones and pheromone receptors. Usually, mating type genes are so dissimilar in DNA sequence (allelic genes and genes ... -

The importance of the presence of gullies in the production of sediments in semiarid areas (Murcia, south-east of Spain)
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaThe study has shown how the existence of gullies remarkably increases the rates of erosion and, therefore, the volume of sediments that arrives at the dikes of hydrological correction. A consequence of this is the need to ... -
Improving the structural stability of cropped soils in Olite (Navarre) using conservation tillage to reduce water erosion
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaThe objective of this work was to compare the soil wet aggregate stability and its relationship to the soil organic matter stock in an agricultural soil under different types of tillage in a semi-arid area of Northern Spain. -
In situ RNA-RNA hybridization: a useful method for analysis of the distribution of transcripts of various genes in Lentinula edodes fruiting bodies
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2006) Contribución a congreso / Biltzarrerako ekarpenaThe in situ RNA-RNA hybridization was renewed understanding that it is a useful method for analysis of the distribution of transcripts of various genes in fruiting bodies of Lentinula edodes. By using this method, we ... -
Influence of snowmelt and heavy rainfalls on water and sediment yield from loess gully catchment (Lublin upland – Poland)
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaThe surface discharge from the gully catchments of the Lublin Upland (Poland) usually is not very high and amounts to about 15 mm·yr-1. It is mainly an episodic discharge of snow/rainfall regime. Surface runoff and ... -
Influence of soil structure, pore-water pressure, and tailwater height on headcut migration in upland concentrated flows
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaThe primary objective of this study was to determine the impact of soil texture, soil pore-water pressure, and tailwater height on scour hole dimensions, migration rate and sediment yield in headcuts migrating under steady ... -
