Rhizobial adaptation to hosts, a new facet in the legume root-nodule symbiosis.

Koch Marion M Delmotte Nathanaël N Rehrauer Hubert H Vorholt Julia A JA Pessi Gabriella G Hennecke Hauke H

Molecular plant-microbe interactions : MPMI 20100601 6

Rhizobia are able to infect legume roots, elicit root nodules, and live therein as endosymbiotic, nitrogen-fixing bacteroids. Host recognition and specificity are the results of early programming events in bacteria and plants, in which important signal molecules play key roles. Here, we introduce a new aspect of this symbiosis: the adaptive response to hosts. This refers to late events in bacteroids in which specific genes are transcribed and translated that help the endosymbionts to meet the di ...[more]

Genome-wide transcription start site mapping of Bradyrhizobium japonicum free-living cells and bacteroids - a rich resource to identify new transcripts, proteins and to study gene regulation

Project description:Background: During the symbiosis with legumes, Bradyrhizobium japonicum cells infect roots where they induce the formation of root nodules and differentiate into intracellular nitrogen-fixing bacteroids. We used differential RNA-seq (dRNA-seq) for the genome-wide detection of transcriptional start sites (TSSs) in B. japonicum USDA 110 cells grown free-living or as bacteroids in soybean root nodules. Results: A newly developed TSS recognition procedure based on machine learning allowed us to map 15,923 TSSs: 14,360 in free-living bacteria, 4,329 in bacteroids and 2,766 in both living conditions. Using a proteogenomics approach, we provide evidence for the translation of 107 new transcripts including 14 with TSSs in annotated genes. In addition, we provide evidence for 178 shorter or longer proteins, 109 of them with TSS support. Based on our TSS map and a new de novo promoter prediction algorithm, we identified promoter motifs mainly used in nodules (similar to RpoN-dependent promoters) or under both conditions (similar to RpoD-dependent promoters). The data is made available in a generic feature format (GFF) file along with an updated and extended genome annotation comprising promoters, TSSs and terminators. The value of such a TSS and promoter map beyond the identification of novel transcripts and ORFs is illustrated by the experimental analysis of an antisense RNA, which is a by-product of transcriptional interference in a gene encoding a cytochrome P450 highly expressed in nodules. Conclusions: The genome-wide TSS and promoter map along with the extended genome annotation represents a very useful resource for detailed analyses of gene regulation and further systems biology studies on B. japonicum in symbiosis with soybean.

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'.

Transcription profiling of soybean nodulation by Bradyrhizobium japonicum

Project description:Legumes interact with nodulating bacteria that convert atmospheric nitrogen into ammonia for plant use. This nitrogen fixation takes place within root nodules that form after infection of root hairs by compatible rhizobia. Using cDNA microarrays, we monitored gene expression in soybean (Glycine max) inoculated with the nodulating bacterium Bradyrhizobium japonicum 4, 8, and 16 days after inoculation (dai), time points that coincided with nodule development and the onset of nitrogen fixation. This experiment identified several thousand genes that were differentially expressed in response to B. japonicum inoculation. Expression of 27 genes was analyzed by qRT-PCR and their expression patterns mimicked the microarray results confirming integrity of analyses. The microarray results suggest that B. japonicum reduces plant defense responses during nodule development. In addition, the data revealed a high level of regulatory complexity (transcriptional, post-transcriptional, translational, post-translational) that is likely essential for development of the symbiosis and adjustment to an altered nutritional status. Keywords = symbiosis Keywords = nodulation Keywords = rhizobium Keywords = defense Keywords = ANOVA Keywords = plant loop design, 7 samples, 7 comparison, 2 technical repeats including dye swaps, 4 biological repeats
