Generation of variability in Chrysodeixis includens nucleopolyhedrovirus (ChinNPV): the role of a single variant
The mechanisms generating variability in viruses are diverse. Variability allows baculoviruses to evolve with their host and with changes in their environment. We examined the role of one genetic variant of Chrysodeixis ... -
Genes ptz and idi, coding for cytokinin biosynthesis enzymes, are essential for tumorigenesis and in planta growth by P. syringae pv. savastanoi NCPPB 3335
The phytopathogenic bacterium Pseudomonas syringae pv. savastanoi elicits aerial tumors on olive plants and is also able to synthesize large amounts of auxins and cytokinins. The auxin indoleacetic acid was shown to be ... -
Genetic variability of Chrysodeixis includens nucleopolyhedrovirus (ChinNPV) and the insecticidal characteristics of selected genotypic variants
Genetic variation in baculoviruses is recognized as a key factor, not only due to the influence of such variation on pathogen transmission and virulence traits, but also because genetic variants can form the basis for novel ... -
Genetic variation and biological activity of two closely related alphabaculoviruses during serial passage in permissive and semi-permissive heterologous hosts
Phylogenetic analyses suggest that Mamestra brassicae multiple nucleopolyhedrovirus (MbMNPV) and Helicoverpa armigera multiple nucleopolyhedrovirus (HearMNPV) may be strains of the same virus species. Most of the studies ... -
Genomic analysis enlightens agaricales lifestyle evolution and increasing peroxidase diversity
As actors of global carbon cycle, Agaricomycetes (Basidiomycota) have developed complex enzymatic machineries that allow them to decompose all plant polymers, including lignin. Among them, saprotrophic Agaricales are ... -
A global synthesis on the effects of forest thinning on hydrological processes: implications for forest management
Forest thinning can significantly affect hydrological processes. However, these effects largely vary with forest types, climate, thinning intensity, and hydrological variables of interest. Understanding these effects and ... -
Glucose counteracts wood-dependent induction of lignocellulolytic enzyme secretion in monokaryon and dikaryon submerged cultures of the white-rot basidiomycete Pleurotus ostreatus
The secretome complexity and lignocellulose degrading capacity of Pleurotus ostreatus monokaryons mkPC9 and mkPC15 and mated dikaryon dkN001 were studied in submerged liquid cultures containing wood, glucose, and wood plus ... -
Glucosinolates as an effective tool in plant-parasitic nematodes control: exploiting natural plant defenses
Plant-parasitic nematodes (PPNs) are an important damaging biotic agent for numerous crops around the world, causing serious losses directly and indirectly. Cultural and chemical control strategies were mainly used to PPNs ... -
Guía de buenas prácticas de poda de la vid
Esta es una guía gráfica e interactiva de buenas prácticas de poda de la vid, en la que se explica mediante vídeos sencillos y de fácil seguimiento cómo cumplir los criterios fundamentales que se deben seguir a la hora de ... -
Guía de buenas prácticas para la elección del material de plantación de un viñedo
Esta es una guía gráfica sobre la elección del material vegetal para la plantación de un viñedo. Mediante vídeos sencillos se explican factores agronómicos claves a tener en cuenta antes de realizar una plantación, ... -
Hemoglobins in the legume–rhizobium symbiosis
Legume nodules have two types of hemoglobins: symbiotic or leghemoglobins (Lbs) and nonsymbiotic or phytoglobins (Glbs). The latter are categorized into three phylogenetic classes differing in heme coordination and O2 ... -
Host range determinants of Pseudomonas savastanoi pathovars of woody hosts revealed by comparative genomics and cross-pathogenicity tests
The study of host range determinants within the Pseudomonas syringae complex is gaining renewed attention due to its widespread distribution in non-agricultural environments, evidence of large variability in intra-pathovar ... -
Hypoxic treatment decreases the physiological action of the herbicide imazamox on pisum sativum roots
The inhibition of acetolactate synthase (ALS; EC 2.2.1.6), an enzyme located in the biosynthetic pathway of branched-chain amino acids, is the target site of the herbicide imazamox. One of the physiological effects triggered ... -
IAOx induces the SUR phenotype and differential signalling from IAA under different types of nitrogen nutrition in Medicago truncatula roots
Indole-3-acetaldoxime (IAOx) is a particularly relevant molecule as an intermediate in the pathway for tryptophan-dependent auxin biosynthesis. The role of IAOx in growth-signalling and root phenotype is poorly studied in ... -
Identification of new antifungal metabolites produced by the yeast Metschnikowia pulcherrima involved in the biocontrol of postharvest plant pathogenic fungi
Several strains of the yeast Metschnikowia pulcherrima exhibit strong antagonistic activity against postharvest pathogens and may have broad biotechnological potential as biocontrol agents. However, the nature and ... -
Iflavirus covert infection increases susceptibility to nucleopolyhedrovirus disease in Spodoptera exigua
Naturally occurring covert infections in lepidopteran populations can involve multiple viruses with potentially different transmission strategies. In this study, we characterized covert infection by two RNA viruses, ... -
The importance of the urea cycle and its relationships to polyamine metabolism during ammonium stress in Medicago truncatula
The ornithine–urea cycle (urea cycle) makes a signifcant contribution to the metabolic responses of lower photosynthetic eukaryotes to episodes of high nitrogen availability. In this study, we compared the role of the plant ... -
Increased ascorbate biosynthesis does not improve nitrogen fixation nor alleviate the effect of drought stress in nodulated Medicago truncatula plants
Legume plants are able to establish nitrogen-fixing symbiotic relations with Rhizobium bacteria. This symbiosis is, however, affected by a number of abiotic constraints, particularly drought. One of the consequences of ... -
Increased glyphosate-induced gene expression in the shikimate pathway is abolished in the presence of aromatic amino acids and mimicked by shikimate
The herbicide glyphosate inhibits the plant enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) in the aromatic amino acid (AAA) biosynthetic pathway, also known as the shikimate pathway. Amaranthus palmeri is a ... -
Insecticidal activity of bacillus thuringiensis proteins against coleopteran pests
Bacillus thuringiensis is the most successful microbial insecticide agent and its proteins have been studied for many years due to its toxicity against insects mainly belonging to the orders Lepidoptera, Diptera and ...
