The Mesorhizobium loti purB gene is involved in infection thread formation and nodule development in Lotus japonicus.

چکیده
The purB and purH mutants of Mesorhizobium loti exhibited purine auxotrophy and nodulation deficiency on Lotus japonicus. In the presence of adenine, only the purH mutant induced nodule formation and the purB mutant produced few infection threads, suggesting that 5-aminoimidazole-4-carboxamide ribonucleotide biosynthesis catalyzed by PurB is required for the establishment of symbiosis.

LjnsRING, a novel RING finger protein, is required for symbiotic interactions between Mesorhizobium loti and Lotus japonicus.
Nodule-specific (nodulin) genes are thought to play crucial roles during establishment of the nitrogen-fixing symbiosis between legume plants and Rhizobium bacteria. On the basis of a gene expression database for early stages of the nodulation process of Lotus japonicus, previously constructed by a cDNA macroarray analysis, we identified a novel nodulin gene, LjnsRING, which encodes a protein w...
متن کاملLotus japonicus clathrin heavy Chain1 is associated with Rho-Like GTPase ROP6 and involved in nodule formation.
Mechanisms underlying nodulation factor signaling downstream of the nodulation factor receptors (NFRs) have not been fully characterized. In this study, clathrin heavy chain1 (CHC1) was shown to interact with the Rho-Like GTPase ROP6, an interaction partner of NFR5 in Lotus japonicus. The CHC1 gene was found to be expressed constitutively in all plant tissues and induced in Mesorhizobium loti-i...
متن کاملThe small GTPase ROP6 interacts with NFR5 and is involved in nodule formation in Lotus japonicus.
Nod Factor Receptor5 (NFR5) is an atypical receptor-like kinase, having no activation loop in the protein kinase domain. It forms a heterodimer with NFR1 and is required for the early plant responses to Rhizobium infection. A Rho-like small GTPase from Lotus japonicus was identified as an NFR5-interacting protein. The amino acid sequence of this Rho-like GTPase is closest to the Arabidopsis (Ar...
متن کاملLotus japonicus alters in planta fitness of Mesorhizobium loti dependent on symbiotic nitrogen fixation
Rhizobial bacteria are known for their capacity to fix nitrogen for legume hosts. However ineffective rhizobial genotypes exist and can trigger the formation of nodules but fix little if any nitrogen for hosts. Legumes must employ mechanisms to minimize exploitation by the ineffective rhizobial genotypes to limit fitness costs and stabilize the symbiosis. Here we address two key questions about...
متن کاملRNAi knock-down of ENOD40s leads to significant suppression of nodule formation in Lotus japonicus.
ENOD40 is one of the most intriguing early nodulin genes that is known to be induced very early in response to interaction of legume plants with symbiotic Rhizobium bacteria, but its function in the nodulation process is still not known. Lotus japonicus has two ENOD40 genes: LjENOD40-1 is abundantly induced in very early stages of bacterial infection or Nod factor application, whereas LjENOD40-...
