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 ... -
Insecticidal traits of variants in a genotypically diverse natural isolate of anticarsia gemmatalis multiple nucleopolyhedrovirus (AgMNPV)
Outbreaks of Anticarsia gemmatalis (Hübner, 1818) (Lepidoptera: Erebidae), a major pest of soybean, can be controlled below economic thresholds with methods that do not involve the application of synthetic insecticides. ... -
Invertebrate community of Scots pine coarse woody debris in the Southwestern Pyrenees under different thinning intensities and tree species
Background and Objectives: The forest in the Southwestern Pyrenees Mountains (Northern Spain) is mainly composed of pure Pinus sylvestris L. or a mix of P. sylvestris and Fagus sylvatica L. The most common forest management ... -
It's not you, it's me: Medicago truncatula efd-1 mutant phenotype depends on rhizobium symbiont
The work by Jardinaud et al. (2022a) illustrates the need to reconsider the identification of genes with a functional role in symbiosis when using a model system in which nodule development and plant growth are constrained ... -
Latest trends in modelling forest ecosystems: new approaches or just new methods?
Purpose of Review: Forest models are becoming essential tools in forest research, management, and policymaking but currently are under deep transformation. In this review of the most recent literature (2018–2022), we aim ... -
Learning plant biodiversity in nature: the use of the citizen–science platform iNaturalist as a collaborative tool in secondary education
Biodiversity is a concept of great scientific interest and social value studied in different subjects of the secondary education curriculum. Citizen–science programs may contribute to increasing the engagement of students ... -
Long-term carbon sequestration in pine forests under different silvicultural and climatic regimes in Spain
Proactive silviculture treatments (e.g., thinning) may increase C sequestration contributing to climate change mitigation, although, there are still questions about this effect in Mediterranean pine forests. The aim of ... -
LysM proteins in mammalian fungal pathogens
The LysM domain is a highly conserved carbohydrate-binding module that recognizes polysaccharides containing N-acetylglucosamine residues. LysM domains are found in a wide variety of extracellular proteins and receptors ... -
MADERA: a standardized pan-amazonian dataset for tropical timber species
We compiled and presented a dataset for all timber species reported in the Amazon region from all nine South American Amazonian countries. This was based on official information from every country, as well as from two ... -
Mechanisms involved in drought stress tolerance triggered by rhizobia strains in wheat
Rhizobium spp. is a well-known microbial plant biostimulant in non-legume crops, but little is known about the mechanisms by which rhizobia enhance crop productivity under drought stress. This work analyzed the mechanisms ... -
Medicago sativa and Medicago truncatula show contrasting root metabolic responses to drought
Drought is an environmental stressor that affects crop yield worldwide. Understandingplant physiological responses to stress conditions is needed to secure food in futureclimate conditions. In this study, we applied a ... -
Metschnikowia pulcherrima as an efficient biocontrol agent of Botrytis cinerea infection in apples: unraveling protection mechanisms through yeast proteomics
The results obtained in this study show that the Mp-30 strain of Metschnikowia pulcherrima is able to completely prevent Botrytis cinerea infection in apples, which is a major postharvest disease of fruits throughout the ... -
Microorganisms as biocontrol agents against bacterial citrus diseases
Citrus represents one of the most widely grown crops on the planet, extensively cultivated for both the fresh fruit and juice markets. The productivity of citrus orchards can be seriously affected by highly aggressive ... -
The moderate oxidative stress induced by glyphosate is not detected in Amaranthus palmeri plants overexpressing EPSPS
The present study aimed to determine whether glyphosate-induced oxidative stress is directly related to the action mechanism of this herbicide (5-enolpyruvylshikimate-3-phosphate synthase or EPSPS inhibition) and analyse ... -
ModulaTransprot: explorando el uso de la nutrición amoniacal para reducir contenidos de nitrato en hortalizas de hoja en sistemas de cultivo sin suelo
Encontrar alternativas a través del diseño de productos y sistemas sostenibles que aumenten la eficiencia en el uso del nitrógeno y disminuya los contenidos de nitratos en tejidos comestibles es una necesidad científica, ...
