Abstract
Two factors that are well-known to influence soil microbiomes include the depth of the soil as well as the level of moisture. Previous works have demonstrated that climate change will increase the incidence of drought in soils, but it is unknown how fluctuations in moisture availability affect soil microbiome composition and functioning down the depth profile. Here, we investigated soil and wheatgrass rhizosphere microbiomes in a common field setting under four different irrigation regimes and three depths. We demonstrated that there is a significant interactive effect, where fluctuations in soil moisture more strongly influence soil microbiomes at the surface layer than in deeper layers, including for soil community composition, diversity, and for functional profiles. Meanwhile, in rhizosphere communities the influence of irrigation was similar across the different depths, although there were slight discrepancies between the two cultivars of wheatgrass used. The lessened response of deeper soil microbiomes to changes in irrigation may be due to higher incidence of slow-growing, stress-resistant microbes.

Project description:In this study, a cross species hybridization (CSH) approach was used to evaluate whole transcriptome changes during carotenoid accumulation in the storage root of carrot (Daucus carota). Carotenoids are isoprenoid compounds providing red, yellow and orange color to plants. Previous gene expression analyses of carotenoid accumulation in non-model plant species have primarily used a candidate gene approach. Since global transcriptome analyses require extensive genome sequence, in the absence of these genomic resources an alternate approach uses platforms developed for model plant species. To assess transcriptome patterns associated with carotenoid pigmentation in carrot storage root, two carrot sibling inbred lines, B8788, true breeding for orange color and B8750, true breeding for white root color, were hybridized to the Medicago Affymetrix GeneChip microarray.

Project description:Cultivated carrot (Daucus carota L. ssp. sativus) was domesticated from wild carrot (Daucus carota L. ssp. carota) with radical different traits. The aim of this study was to compare the root transcriptomes between cultivated and wild carrots for SNP discovery, inferring domestication process, and identifying domestication genes. Six cultivated carrots representing main European carrot root types and five wild carrot populations from widely dispersed sites were used. The root transcriptomes were sequenced with multiplexing paried-end sequencing in Illumina Genome Analyzer IIx.

Near isogenic recombinant inbred lines B8788 and B8750, derived from a cross between white rooted wild carrot (QAL) and orange-rooted B493 were used for comparative analyzes to minimize background genetic differences. B8788 is true breeding for orange color whereas B8750 is true breeding for white storage root color. Carrots were grown in three pots for each genotype under greenhouse conditions and carrots were selected arbitrarily from these pots for harvest. Roots were harvested at approximately 11 weeks post planting when carotenoid accumulation becomes apparent in the storage root. Storage root tissue from sixteen individual carrot roots was pooled into three one-gram tissue pools of four carrots for each genotype.

Project description:The goal of this growth chamber experiment was to investigate the effects of diverse soil microbial communities on the transcriptional responses of plants to drought. Specifically, we sought to understand how soil microbiomes' past exposure to water-limited conditions (either long-term exposure to dry conditions in low-precipitation sites, or recent acute drought) impacted their interactions with plants. Six soils collected from remnant prairies crossing a steep precipitation gradient in Kansas, USA were used as the starting microbial communities. Thirty-two pots (or mesocosms) of each soil were divided among four treatments: droughted or well-watered, and with or without a host plant (Tripsacum dactyloides) in a factorial design. The soil mesocosms were "conditioned" in these treatments for five months. (Metagenome and metatranscriptome data from the baseline soils and the post-conditioning soils are available in a separate BioProject on NCBI SRA and GEO). Then, a microbial slurry extracted from each of the 192 conditioned soils was used to inoculate 4 plants in a subsequent experiment (the “Test Phase”): one pot per combination of watering treatment (droughted or control) and host species (Zea mays or Tripsacum dactyloides). After 4 weeks (for maize) or 5 weeks (for eastern gamagrass) we harvested one crown root per plant for 16S rRNA sequencing and another crown root for RNA-seq. The 16S and RNA-seq data for these plants (both species) are contained in this BioProject. Note that 16S rRNA sequencing data are available for all plants in this experiment, but we conducted RNA-seq only for a subset (all plants grown in microbiomes originating from the 2 driest and 2 wettest collection sites).

Project description:The spread of antibiotic resistance genes (ARG) into agricultural soils, products, and foods severely limits the use of organic fertilizers in agriculture. In this study, experimental land plots were fertilized, sown, and harvested for two consecutive agricultural cycles using either mineral or three types of organic fertilizers: sewage sludge, pig slurry, or composted organic fraction of municipal solid waste. The analysis of the relative abundances of more than 200,000 ASV (Amplicon Sequence Variants) allowed the identification of a small, but significant (<10%) overlap between soil and fertilizer microbiomes, particularly in soils sampled the same day of the harvest (post-harvest soils). Loads of clinically relevant ARG were significantly higher (up to 100 fold) in fertilized soils relative to the initial soil. The highest increases corresponded to post-harvest soils treated with organic fertilizers, and they correlated with the extend of the contribution of fertilizers to the soil microbiome. Edible products (lettuce and radish) showed low, but measurable loads of ARG (sul1 for lettuces and radish, tetM for lettuces). These loads were minimal in mineral fertilized soils, and strongly dependent on the type of fertilizer. We concluded that at least part of the observed increase on ARG loads in soils and foodstuffs were actual contributions from the fertilizer microbiomes. Thus, we propose that adequate waste management and good pharmacological and veterinarian practices may significantly reduce the potential health risk posed by the presence of ARG in agricultural soils and plant products.
