Transcriptome and metabolome analysis support that nitrate primarily promotes N and C metabolism in soybean roots and reduces those in nodules.

ABSTRACT: To dissect differences in gene expression profile of soybean roots and root nodules, we have employed microarray analysis. Seeds of soybean (Glycine max L. cv. Nourin No. 2) were inoculated with rhizobia (Bradyrhizobium diazoefficiens USDA110) and were hydroponically cultivated under controlled conditions with nitrogen free culture solution (Saito et al. 2014). At 19 days after planting, each plant were treated with or without 5 mM nitrate for 24 hours. Roots and nodules from three plants were pooled with three biological replications, and total RNA was extracted.

Metabolomic profiling of Bradyrhizobium diazoefficiens-induced root nodules reveals both host plant-specific and developmental signatures

Project description:Metabolomics and transcriptomics of Bradyrhizobium diazoefficiens-induced root nodules Bradyrhizobium diazoefficiens is a nitrogen-fixing endosymbiont, which can grow inside root-nodule cells of the agriculturally important soybean and other host plants. Our previous studies described B. diazoefficiens host-specific global expression changes occurring during legume infection at the transcript and protein level. In order to further characterize nodule metabolism, we here determine by flow injection -time of flight mass spectrometry analysis the metabolome of i) nodules and roots from four different B. diazoefficiens host plants, ii) soybean nodules harvested at different time points during nodule development, and iii) soybean nodules infected by two strains mutated in key genes for nitrogen fixation, respectively. Ribose (soybean), tartaric acid (mungbean), hydroxybutanoyloxybutanoate (siratro) and catechol (cowpea) were among the metabolites found to be specifically elevated in one of the respective host plants. While the level of C4-dicarboxylic acids decreased during soybean nodule development, we observed an accumulation of trehalose-phosphate at 21 days post infection (dpi). Moreover, nodules from non-nitrogen-fixing bacteroids (nifA and nifH mutants) showed specific metabolic alterations; these were also supported by transcriptomics data that was generated for the two mutant strains and were helpful to separate for some examples the respective bacterial and plant contributions to the metabolic profile. The alterations included signs of nitrogen limitation in both mutants, and an increased level of a phytoalexin in nodules induced by the nifA mutant, suggesting that the tissue of these nodules exhibits defense and stress reactions.

Proteomic Characterization of Bradyrhizobium diazoefficiens bacteroids during soybean root nodules senescence

Project description:The form and physiology of Bradyrhizobium diazoefficiens after the decline of symbiotic nitrogen fixation has been characterized. Proteomic analyses showed that the post-symbiotic B. diazoefficiens undergo metabolic remodeling as well defined groups of proteins declined, increased or remained unchanged from 56 to 119 days after planting suggesting a transition to a hemibiotrophic-like lifestyle. Enzymatic analysis showed distinct patterns in both the cytoplasm and the periplasm. Similar to the bacteroid, the post-symbiotic bacteria rely on a non-citric acid cycle supply of succinate and although viable, they did not demonstrate the ability to grow within the senescent nodule.

Treanscriptomes of emering nodules, mature nodules, emerging lateral roots, and young lateral roots in soybean

Project description:Symbiotic legume nodules and lateral roots arise away from the root meristem via dedifferentiation events. While these organs share some morphological and developmental similarities, whether legume nodules are modified lateral roots is an open question. We dissected emerging nodules (EN), mature nodules (MN), emerging lateral roots (ELR) and young lateral roots (YLR), and constructed strand-specific RNAseq libraries using polyA-enriched RNA preparations. Root sections above and below these organs devoid of any lateral organs were used to construct respective control tissue libraries (ABEN, ABMN, ABELR, ABYLR respectively). High sequence quality, predominant mapping to coding sequences, and consistency between replicates indicated that the RNAseq libraries were of very high quality. We identified genes enriched in emerging nodules, mature nodules, emerging lateral roots and young lateral roots in soybean by comparing global gene expression profiles between each of these organs and adjacent root segments. Potential uses for this high quality transcriptome data set include generation of global gene regulatory networks to identify key regulators; metabolic pathway analyses and comparative analysis of key gene families to discover organ-specific biological processes; and identification of organ-specific alternate spliced transcripts. When combined with other similar datasets especially from leguminous plants these analyses can help answer questions on the evolutionary origins of root nodules and relationships between the development of different plant lateral organs.

Differential compatibilities between rhizobium strains and cultivated and wild soybeans revealed by anatomical and RNA-seq analyses.

Project description:Various species of rhizobium establish compatible symbiotic relationships with soybean (Glycine max) leading to the formation of nitrogen-fixing nodules in roots. The formation of functional nodules is mediated through complex developmental and transcriptional reprogramming that involves the activity of thousands of plant genes. However, host transcriptome responses that determine the outcome of the symbiotic interactions leading to the formation of functional or non-functional nodules remain unexplored. In this study, we investigated differential compatibilities between rhizobium strains (Bradyrhizobium diazoefficiens USDA 110Bradyrhizobium sp. strain LVM 105) and cultivated and wild soybeans. The nodulation assays revealed that both USDA 110 and LVM 105 strains effectively nodulate G. soja but only USDA 110 can form symbiotic relationships with Williams 82. RNA-seq data revealed that USDA 110 and LVM 105 induce distinct transcriptome programming in functional mature nodules formed on G. soja roots where genes involved in nucleosome assembly, DNA replication, regulation of cell cycle, and defense responses play key roles. Transcriptome comparison also suggested that activation of genes associated with cell wall biogenesis and organization and defense responses together with downregulation of genes involved in the biosynthesis of isoprenoids and antioxidant stress are associated with the formation of non-functional nodules on Williams 82 roots. Moreover, our analysis implies that increased activity of genes involved in oxygen binding, amino acid transport, and nitrate transport differentiates between fully-developed nodules in cultivated versus wild soybeans.

Shotgun proteomics of soybean root nodules infected by Bradyrhizobium japonicum

Project description:Global bottom-up proteomics analysis of proteins purified from soybean root nodules infected with either WT or nifH- mutant Bradyrhizobium japonicum. Nine glycoproteins containing Lewis-a N-glycans, with 3 distinct Lewis-a epitopes (Hex:5 HexNAc:4 dHex:3 Pent:1, Hex:4 HexNAc:4 dHex:2 Pent:1, and Hex:4 HexNAc:3 dHex:2 Pent:1) were observed. Proteins purified from WT and nifH- infected soybean root nodules (five biological replicates each) were reduced using dithiothreitol, alkylated with iodoacetamide and trypsin digested followed by C18 SPE clean-up and LC-MS/MS analysis. Raw data files were processed using FragPipe v17.1, then output files 'combined_modified_peptide.tsv' and 'combined_protein.tsv' were used to identify glycopeptides and for global protein quantitation. These files, along with Excel files containing global quantitation analysis files for soybean nodule (Glycine max) and bacterial (Bradyrhizobium), are available in directory 'Quantification/MSFragger_results'. Glycopeptide data were also processed with PMI Byonic, and Excel file results are available in directory 'Quantification/PMI_Byonic_results'.

Genome wide transcriptome analysis reveals complex regulatory mechanisms underlying phosphate homeostasis in soybean nodules

Project description:Phosphorus (P) deficiency is a major limitation for legume crop production. Although overall adaptations of plant roots to P deficiency have been extensively studied, fragmentary information is available in regards to root nodule responses to P deficiency. In this study, genome wide transcriptome analysis was conducted using RNA-seq analysis to investigate molecular mechanisms underlying soybean (Glycine max) nodule adaptation to phosphate (Pi) starvation. Phosphorus deficiency significantly decreased soybean nodule growth and nitrogenase activity. Nodule Pi concentrations declined by 49% in response to P deficiency, but this was well below the 87% and 88% decreases observed in shoots and roots, respectively. Nodule transcript profiling revealed that a total of 2,055 genes exhibited differential expression patterns between Pi sufficient and deficient conditions. A set of DEGs appeared to be involved in maintaining Pi homeostasis in soybean nodules, including 8 Pi transporters (PTs), 8 proteins containing the SYG1/PHO81/XPR1 domain (SPXs), and 16 purple acid phosphatases (PAPs). The results suggest that a complex transcriptional regulatory network participates in soybean nodule adaption to Pi starvation, most notable a Pi signaling pathway specifically involved in maintaining Pi homeostasis in nodules.

Pleiotropic effects of PhaR regulator in Bradyrhizobium diazoefficiens microaerobic metabolism

Project description:Bradyrhizobium diazoefficiens can live inside soybean root nodules and in free-living conditions. In both states, when oxygen levels decrease, cells adjust their protein pools by gene transcription modulation. PhaR encodes a transcription factor annotated as PHA (polyhydroxyalkanoate) accumulation regulator. We found that PhaR not only controls the PHA cycle but also acts as a global regulator of excess carbon allocation by controlling the expression of fixK2 and nifA genes, both encoding key transcription factors for microoxic and symbiotic metabolism in B. diazoefficiens. The function of PhaR was expanded by a multi-pronged approach that includes analysis of the effects of phaR mutation at transcriptional and protein levels of putative PhaR targets and direct control mediated by PhaR determined by EMSA assays. We also were able to identify PhaR, phasins and other proteins associated with PHA granules which confirmed a global function of PhaR in microoxia.
