Project description:We used wheat as rotational crop to assess the influence of continuous cropping on microbiome in Pinellia ternata rhizosphere and the remediation of rotational cropping to the impacted microbiota. Illumina high-throughput sequencing technology was utilized for this method to explore the rhizosphere microbial structure and diversity based on continuous and rotational cropping.

Project description:In this study, we used transcriptomic and hormonomic approaches to examine drought-induced changes in barley roots and leaves and its rhizosphere. By studying hormonal responses, alternative splicing events in barley, and changes in the rhizosphere microbiome, we aimed to provide a comprehensive view of barley drought-adaptive mechanisms and potential plant-microbe interactions under drought stress. This approach improved our understanding of barley adaptive strategies and highlighted the importance of considering plant-microbe interactions in the context of climate change.

Project description:Phosphate (P) fertilization induces a myriad of plant rhizosphere processes, required for a better P plant use. However, extended knowledge about plant responses to polyphosphates (PolyP) is still scarce, particularly transcriptomic and functional traits of root-induced rhizosphere processes. The present study aims to investigate belowground traits related to root transcriptomic changes, rhizosphere acidification, root growth, and P acquisition of durum wheat under PolyPs (PolyB and PolyC) supply. Root molecular traits were differentially expressed in response to PolyPs types, with 2481 and 184 genes were differentially expressed (compared to OrthoP) under PolyB (445 up- and 2036 down-regulated) and PolyC (71 up- and 113 down-regulated), respectively. Specifically, PolyB significantly influenced the expression of genes encoding the key enzymes in glycolysis, citrate cycle and acid phosphatases, OGDH, MDH, and ENO, PAP21 genes were upregulated, while TPI, PFK and LDH genes were downregulated. The modulated expression of TCA cycle and PAP genes can presumably explain the induced rhizosphere acidification (pH decreased from 8 to 6.3) and acid phosphatases activity (in root, rhizosphere soil and rhizosphere soil solution) under PolyPs, which consequently increased rhizosphere soil P availability (145% compared to OrthoP). This increase in P availability was concomitant with the modulation of root morphological traits and the upregulation of the AUX1 and ABA transporters genes, indicating PolyPs regulatory role in root growth for efficient P uptake. Moreover, PolyB significantly upregulated the expression of SPX3, which is indispensable for the absorption and transport of inorganic P to both roots and shoots. This was physiologically reflected by the increased shoot (36%) and root (61%) Pi contents in response to PolyB compared to OrthoP. Taken together, our findings provide novel and consistent evidence that enhanced P acquisition from PolyPs entails coordinated regulation of the expression of genes related to root-rhizosphere processes (rhizosphere acidification and phosphatases exudation) and root morphology, which consequently induces physiological adaptive traits enabling enhanced availability, acquisition of P, and wheat growth performance.

Project description:We present metaproteome data from wheat rhizosphere from saline and non-saline soil. For collection and acquisition of metaproteome from wheat rhizosphere under saline and normal conditions, a survey was conducted in regions of Haryana, India. Samples from 65 days old plants (wheat var HD2967) were collected and pooled and based on EC,saline (NBAIM B; EC 6mS cm-1; pH 9.0; Bhaupur 2, Haryana, INDIA; 29°19'8"N;76°48'53"E) and normal soil samples (NBAIM C; EC 200 uS cm-1; pH 7.2; Near Nainform, Haryana, INDIA; 29°19'8"N;76°48'53"E) were selected for isolation of proteome with the standardized protocol at our laboratory followed by metaproteome analysis with the standardized pipepline. In total 1538 and 891 proteins were obtained from wheat rhizosphere from saline and non-saline respectively with the given parameters and software. Among 1410 proteins unique for saline soil, proteins responsible for glycine, serine and threonine metabolism and arginine and proline biosynthesis were found in saline and absent in non-saline. The present study extends knowledge about the physiology and adaptations of the wheat rhizosphere associated microbiota under saline soil.

Project description:Arsenic (As) bioavailability in the rice rhizosphere is influenced by many microbial interactions, particularly by metal-transforming functional groups at the root-soil interface. This study was conducted to examine As-transforming microbes and As-speciation in the rice rhizosphere compartments, in response to two different water management practices (continuous and intermittently flooded), established on fields with high to low soil-As concentration. Microbial functional gene composition in the rhizosphere and root-plaque compartments were characterized using the GeoChip 4.0 microarray. Arsenic speciation and concentrations were analyzed in the rhizosphere soil, root-plaque, porewater and grain samples. Results indicated that intermittent flooding significantly altered As-speciation in the rhizosphere, and reduced methyl-As and AsIII concentrations in the pore water, root-plaque and rice grain. Ordination and taxonomic analysis of detected gene-probes indicated that root-plaque and rhizosphere assembled significantly different metal-transforming functional groups. Taxonomic non-redundancy was evident, suggesting that As-reduction, -oxidation and -methylation processes were performed by different microbial groups. As-transformation was coupled to different biogeochemical cycling processes establishing functional non-redundancy of rice-rhizosphere microbiome in response to both rhizosphere compartmentalization and experimental treatments. This study confirmed diverse As-biotransformation at root-soil interface and provided novel insights on their responses to water management, which can be applied for mitigating As-bioavailability and accumulation in rice grains.
