Application of anti-transpirants temporarily alleviates the inhibition of symbiotic nitrogen fixation in drought-stressed pea plants
Stomatal closure is one of the first plant responses under a water deficit situation. This leads to a decline in transpiration but also in the plant photosynthetic activity. Legume plants grown under symbiosis with rhizobium ... -
Bioinformatic approach for transcriptomics: integration of gene expression data based on RNA-seq with tissue localization
(2023) Trabajo Fin de Grado/Gradu Amaierako LanaOne of the main challenges in current system biology research comes when different types of data must be accessed from various sources, metrics and visualization and analysis tools. The challenge increases when it comes ... -
The CCAAT box-binding transcription factor NF-YA1 controls rhizobial infection
Symbiosis between legume plants and soil rhizobia culminates in the formation of a novel root organ, the 'nodule', containing bacteria differentiated as facultative nitrogen-fixing organelles. MtNF-YA1 is a Medicago ... -
Drought stress provokes the down-regulation of methionine and ethylene biosynthesis pathways in Medicago truncatula roots and nodules
Symbiotic nitrogen fixation is one of the first physiological processes inhibited in legume plants under water-deficit conditions. Despite the progress made in the last decades, the molecular mechanisms behind this ... -
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 ... -
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 ... -
Integrative approaches for the analysis of abiotic stress responses in the legume-Rhizobium symbiosis: from shoots to roots
La actual población mundial junto con las predicciones de un mayor crecimiento sugieren que es necesario incrementar el rendimiento de los cultivos a nivel mundial. Las leguminosas son el segundo cultivo más importante ... -
Nodule carbohydrate catabolism is enhanced in the Medicago truncatula A17-Sinorhizobium medicae WSM419 symbiosis
The symbiotic association between Medicago truncatula and Sinorhizobium meliloti is a well-established model system in the legume–Rhizobium community. Despite its wide use, the symbiotic efficiency of this model has been ... -
A novel biosensor to monitor proline in pea root exudates and nodules under osmotic stress and recovery
Background and aims: Plant and bacteria are able to synthesise proline, which acts as a compound to counteract the negative effects of osmotic stresses. Most methodologies rely on the extraction of compounds using destructive ... -
A plant gene encoding one-heme and two-heme hemoglobins with extreme reactivities toward diatomic gases and nitrite
In plants, symbiotic hemoglobins act as carriers and buffers of O2 in nodules, whereas nonsymbiotic hemoglobins or phytoglobins (Glbs) are ubiquitous in tissues and may perform multiple, but still poorly defined, functions ... -
Propuesta cooperativa de un sistema acuapónico para proyecto trianual “Conócete, Quiérete, Cuídate” del I.E.S Basoko para la enseñanza transversal de la salud y el medio ambiente
Ante los cambios vertiginosos de nuestra sociedad, el excesivo crecimiento demográfico que está derivando en una sobre explotación de los recursos y un consumo exacerbado, se ve necesario un cambio de paradigma, el cual ... -
Split‐root systems applied to the study of the legume‐rhizobial symbiosis: what have we learned?
Split-root system (SRS) approaches allow the differential treatment of separate and independent root systems, while sharing a common aerial part. As such, SRS is a useful tool for the discrimination of systemic (shoot ... -
Three classes of hemoglobins are required for optimal vegetative and reproductive growth of Lotus japonicus: genetic and biochemical characterization of LjGlb2-1
Legumes express two major types of hemoglobins, namely symbiotic (leghemoglobins) and non-symbiotic (phytoglobins), with the latter being categorized into three classes according to phylogeny and biochemistry. Using knockout ...
