Project description:The current study is aimed at elucidating the proteomic responses in durum wheat Triticum aestivum L triggered by native PGPB, CP_4 (Bacillus subtilis) alone and in combination with AM fungi Glomus fasciculatum under field conditions Our results suggest that native PGPB B subtilis ( in combination with AM fungi Glomus fasciculatum (B+ may promote differential abundance of multiple regulatory seed storage proteins over untreated control Thus, combined application of native PGPB and AMF could offer a more sustainable approach to enhance crop yield.

Project description:It has been demonstrated that wheat overexpressing Pm3b, an allele of the R gene Pm3, has enhanced resistance against powdery mildew under field conditions. A gene expression profile study using GeneChip® Wheat Genome Array was performed to obtain insights into the mode of action of Pm3b and to elucidate the molecular basis of pleiotropic effects observed in three out of four independent transgenic events tested under field conditions.

Project description:Background: The soil environment is responsible for sustaining most terrestrial plant life on earth, yet we know surprisingly little about the important functions carried out by diverse microbial communities in soil. Soil microbes that inhabit the channels of decaying root systems, the detritusphere, are likely to be essential for plant growth and health, as these channels are the preferred locations of new root growth. Understanding the microbial metagenome of the detritusphere and how it responds to agricultural management such as crop rotations and soil tillage will be vital for improving global food production. Methods: The rhizosphere soils of wheat and chickpea growing under + and - decaying root were collected for metagenomics sequencing. A gene catalogue was established by de novo assembling metagenomic sequencing. Genes abundance was compared between bulk soil and rhizosphere soils under different treatments. Conclusions: The study describes the diversity and functional capacity of a high-quality soil microbial metagenome. The results demonstrate the contribution of the microbiome from decaying root in determining the metagenome of developing root systems, which is fundamental to plant growth, since roots preferentially inhabit previous root channels. Modifications in root microbial function through soil management, can ultimately govern plant health, productivity and food security.

Project description:Microarrays were used to identify transcriptional responses in field-grown root material of wheat in order to dissect specific gene expression responses to limited macronutrient availability, particularly phosphate. This study fills the gap between the transcriptome studies on model plants and the lack of studies on soil-grown wheat aiming to identify candidate genes for enhancing nutrient uptake efficiency. The work at Rothamsted Research is supported via the 20:20 Wheat® Programme by the UK Biotechnology and Biological Sciences Research Council. The contribution was supported by BIONUT-ITN and the research leading to these results has received funding from the European Union Seventh Framework Programme (FP7/2007-2013) under grant agreement no. 264296. T. aestivum cv. Hereward root material was excavated in triplicates in May 2011 at booting stage from sections 0 and 1 plots representing continuous wheat plots of the “Broadbalk” field experiment at Rothamsted Research, UK (http://www.rothamsted.ac.uk/sample-archive/guide-classical-and-other-long-term-experiments-datasets-and-sample-archive). The distinct peculiarity of these plots, including a control plot with nutrient replete wheat plants, is the withdrawal of N, P, K, Mg and S fertilizers exposing the plants to multiple long-term nutrient deficiencies and representing 6 treatments ; 12 samples were analysed.

Project description:To effectively monitor microbial populations in acidic environments and bioleaching systems, a comprehensive 50-mer-based oligonucleotide microarray was developed based on most of the known genes associated with the acidophiles. This array contained 1,072 probes in which there were 571 related to 16S rRNA and 501 related to functional genes. Acid mine drainage (AMD) presents numerous problems to the aquatic life and surrounding ecosystems. However, little is known about the geographic distribution, diversity, composition, structure and function of AMD microbial communities. In this study, we analyzed the geographic distribution of AMD microbial communities from twenty sites using restriction fragment length polymorphism (RFLP) analysis of 16S rRNA genes, and the results showed that AMD microbial communities were geographically distributed and had high variations among different sites. Then an AMD-specific microarray was used to further analyze nine AMD microbial communities, and showed that those nine AMD microbial communities had high variations measured by the number of detected genes, overlapping genes between samples, unique genes, and diversity indices. Statistical analyses indicated that the concentrations of Fe, S, Ca, Mg, Zn, Cu and pH had strong impacts on both phylogenetic and functional diversity, composition, and structure of AMD microbial communities. This study provides insights into our understanding of the geographic distribution, diversity, composition, structure and functional potential of AMD microbial communities and key environmental factors shaping them. This study investigated the geographic distribution of Acid Mine Drainages microbial communities using a 16S rRNA gene-based RFLP method and the diversity, composition and structure of AMD microbial communities phylogenetically and functionally using an AMD-specific microarray which contained 1,072 probes ( 571 related to 16S rRNA and 501 related to functional genes). The functional genes in the microarray were involved in carbon metabolism (158), nitrogen metabolism (72), sulfur metabolism (39), iron metabolism (68), DNA replication and repair (97), metal-resistance (27), membrane-relate gene (16), transposon (13) and IST sequence (11).

Two independent transformation events and respective null segregants as control treated with fungicide or artificially inoculated with powdery mildew.

Project description:Global warming has become a critical challenge to food safety, causing severe yield losses of major crops worldwide. Here, we report that the endophytic bacterium Enterobacter sp. SA187 induces thermotolerance of crops in a sustainable manner. Microbiome diversity of wheat plants is positively influenced by SA187 in open field agriculture, indicating that beneficial microbes can be a powerful tool to enhance agriculture in open field agriculture.
