Brachypodiumdistachyon, etc ; Oryza sativa; genes; genomics; grasses; models; Show all 6 Subjects
Abstract:
... A gene in a given taxonomic group is either present in every individual (core) or absent in at least a single individual (dispensable). Previous pangenomic studies have identified certain functional differences between core and dispensable genes. However, identifying if a gene belongs to the core or dispensable portion of the genome requires the construction of a pangenome, which involves sequenci ...
Brachypodiumdistachyon, etc ; artificial selection; community structure; heritability; leaves; microorganisms; phenotype; rhizosphere; Show all 8 Subjects
Abstract:
... Artificial selection of microbiota opens new avenues for improving plants. However, reported results lack consistency. We hypothesised that the success in artificial selection of microbiota depends on the stabilisation of community structure. In a ten‐generation experiment involving 1,800 plants, we selected rhizosphere microbiota of Brachypodium distachyon associated with high or low leaf greenne ...

Abstract:
... It has been 20 years since Brachypodium distachyon was suggested as a model grass species, but ongoing research now encompasses the entire genus. Extensive Brachypodium genome sequencing programmes have provided resources to explore the determinants and drivers of population diversity. This has been accompanied by cytomolecular studies to make Brachypodium a platform to investigate speciation, pol ...
Brachypodiumdistachyon, etc ; biosensors; cortex; energy transfer; fluorescence; hyphae; metabolism; orthophosphates; plant root cells; vesicular arbuscular mycorrhizae; Show all 10 Subjects
Abstract:
... Arbuscular mycorrhizal (AM) symbiosis is accompanied by alterations to root cell metabolism and physiology, and to the pathways of orthophosphate (Pi) entry into the root, which increase with Pi delivery to cortical cells via arbuscules. How AM symbiosis influences the Pi content and Pi response dynamics of cells in the root cortex and epidermis is unknown. Using fluorescence resonance energy tran ...
... Plants are often sequentially attacked by multiple herbivores; feeding by one herbivore can alter host plant quality that affects the performance of subsequent herbivores. Previous studies suggest that silicon (Si) is a highly inducible defence in grasses (Poaceae) following herbivory, so could mediate such temporally separated insect herbivore interactions. Elevated atmospheric CO₂ concentrations ...
... Gluconacetobacter diazotrophicus is a nitrogen (N) fixing bacterium originally isolated from sugarcane in Brazil. Understanding the interactions between this bacterium and plants is important to exploit the nitrogen-fixing feature of G. diazotrophicus in different crops. Research was conducted to establish, monitor and optimize methods for introducing G. diazotrophicus into Brachypodium distachyon ...

... Root hairs (RHs) function in nutrient and water acquisition, root metabolite exudation, soil anchorage and plant–microbe interactions. Longer or more abundant RHs are potential breeding traits for developing crops that are more resource‐use efficient and can improve soil health. While many genes are known to promote RH elongation, relatively little is known about genes and mechanisms that constrai ...
... The nonexpressor of pathogenesis‐related (NPR) gene family is well known to play a crucial role in transactivation of TGA transcription factors for salicylic acid (SA)‐responsive genes, including pathogenesis‐related protein 1 (PR1), during plants' immune response after pathogen attack in the model dicot Arabidopsis thaliana. However, little is known about NPR gene functions in monocots. We theref ...

Abstract:
... Fusarium graminearum (Fg) causes Fusarium head blight (FHB) disease in wheat and barley. This pathogen produces mycotoxins including deoxynivalenol (DON), the T-2 and fumorisin B1. Translocation of the mycotoxins in grains causes important losses in yields and contributes to serious health problems in humans and livestock. We tested the Bacillus strains, two commercial, QST713 (Serenade®) and FZB2 ...

... KARRIKIN INSENSITIVE2 (KAI2) is an α/β‐hydrolase required for plant responses to karrikins, which are abiotic butenolides that can influence seed germination and seedling growth. Although represented by four angiosperm species, loss‐of‐function kai2 mutants are phenotypically inconsistent and incompletely characterised, resulting in uncertainties about the core functions of KAI2 in plant developme ...
... Pirins are nuclear bicupin proteins, encoded by genes that are one of several gene families that comprise the cupin superfamily in plants. Pirin genes have been implicated in stress response pathways studied in Arabidopsis and At-Pirin1 has been shown to interact with the heterotrimeric G-protein alpha subunit (GPA1). The aim of this study was to identify the members of the Pirin gene family in Tr ...

Abstract:
... Wild plant populations show extensive genetic subdivision and are far from the ideal of panmixia which permeates population genetic theory. Understanding the spatial and temporal scale of population structure is therefore fundamental for empirical population genetics – and of interest in itself, as it yields insights into the history and biology of a species. In this study we extend the genomic re ...
... BACKGROUND: Plant growth devices, for example, rhizoponics, rhizoboxes, and ecosystem fabrication (EcoFAB), have been developed to facilitate studies of plant root morphology and plant-microbe interactions in controlled laboratory settings. However, several of these designs are suitable only for studying small model plants such as Arabidopsis thaliana and Brachypodium distachyon and therefore requ ...
Brachypodiumdistachyon, etc ; codon usage; genetically modified organisms; hydrogen; Show all 4 Subjects
Abstract:
... Brachypodium distachyon, a new monocotyledonous model plant, has received wide attention in biological research due to its small genome and numerous genetic resources. Codon usage bias is an important feature of genes and genomes, and it can be used in transgenic and evolutionary studies. In this study, the nucleotide compositions and patterns of codon usage bias were calculated using Codon W. Add ...
Brachypodiumdistachyon, etc ; Arabidopsis thaliana; cell polarity; microscopy; statistical analysis; Show all 5 Subjects
Abstract:
... Quantitative information on the spatiotemporal distribution of polarised proteins is central for understanding cell‐fate determination, yet collecting sufficient data for statistical analysis is difficult to accomplish with manual measurements. Here we present Polarity Measurement (Pome), a semi‐automated pipeline for the quantification of cell polarity and demonstrate its application to a variety ...

Abstract:
... To what degree can the lignin subunits in a monocot be derived from monolignol ferulate (ML‐FA) conjugates? This simple question comes with a complex set of variables. Three potential requirements for optimizing ML‐FA production are as follows: (1) The presence of an active FERULOYL‐CoA MONOLIGNOL TRANSFERASE (FMT) enzyme throughout monolignol production; (2) Suppression or elimination of enzymati ...
Brachypodiumdistachyon, etc ; Arabidopsis; genes; growth and development; phylogeny; plant growth; root systems; Show all 7 Subjects
Abstract:
... As one kind of plant-specific transcription factors (TFs), WOX (Wuschel-related homeobox) plays an essential role in plant growth and development. In this study, 21 WOX TFs were identified in Brachypodium distachyon. They were divided into ancient, intermediate, and WUS clades based on phylogenetic analysis. These 21 BdWOX genes are mapped on 5 chromosomes unevenly. In the promoters, the most abun ...
Brachypodiumdistachyon, etc ; Helicoverpa armigera; acute exposure; chronic exposure; grasses; phenolic compounds; silicon; Show all 7 Subjects
Abstract:
... Silicon (Si) can adversely affect insect herbivores, particularly in plants that evolved the ability to accumulate large quantities of Si. Very rapid herbivore‐induced accumulation of Si has recently been demonstrated, but the level of protection against herbivory this affords plants remains unknown. Brachypodium distachyon, a model Si hyperaccumulating grass, was exposed to the chewing herbivore, ...

Abstract:
... Although studied for more than a century, the spatial distribution of microorganisms in a root system still remains partly understood. In a repeated greenhouse experiment using the model plant Brachypodium distachyon, we investigated the composition and distribution of rhizosphere bacteria and their response to inoculation with artificially selected microbial communities, using two different sampl ...
