Abstract:: ... NodMl-V(C[subscript 18:1], Me, Cb, AcFuc) is a major component of lipo-chitin oligosaccharides (LCOs), or Nod factors, produced by Mesorhizobium loti. The presence of a 4-O-acetylated fucosyl residue (AcFuc) at the reducing end has been thought to be essential for symbiotic interactions with the compatible host plant, Lotus japonicus. We generated an M. loti mutant in which the nolL gene is disrup ...

Abstract:: ... The developmental program of nodulation is regulated systemically in leguminous host species. A mutant astray (Ljsym77) in Lotus japonicus has lost some sort of its ability to regulate this symtem, and shows enhanced and early nodulation. In the absence of rhizobia, this mutant exhibits characteristics associated with defects in light and gravity responses. These nonsymbiotic phenotypes of astray ...

Abstract:: ... In the Rhizobium-legume symbiosis, calcium/calmodulin-dependent protein kinase (CCaMK) is a key regulator for both rhizobial infection and nodule organogenesis. Deregulation of CCaMK by either a point mutation in the autophosphorylation site or the deletion of the carboxyl-terminal regulatory domain results in spontaneous nodule formation without rhizobia. However, the underlying biochemical mecha ...

Abstract:: ... The initiation of intracellular infection of legume roots by symbiotic rhizobia bacteria and arbuscular mycorrhiza (AM) fungi is preceded by the induction of calcium signatures in and around the nucleus of root epidermal cells. Although a calcium and calmodulin-dependent kinase (CCaMK) is a key mediator of symbiotic root responses, the decoding of the calcium signal and the molecular events downst ...

Abstract:: ... A symbiotic mutant of Lotus japonicus, called sunergos1‐1 (suner1‐1), originated from a har1‐1 suppressor screen. suner1‐1 supports epidermal infection by Mesorhizobium loti and initiates cell divisions for organogenesis of nodule primordia. However, these processes appear to be temporarily stalled early during symbiotic interaction, leading to a low nodule number phenotype. This defect is ephemer ...

Abstract:: ... Infection thread-dependent invasion of legume roots by rhizobia leads to internalization of bacteria into the plant cells, which is one of the salient features of root nodule symbiosis. We found that two genes, Nap1 (for Nck-associated protein 1) and Pir1 (for 121F-specific p53 inducible RNA), involved in actin rearrangements were essential for infection thread formation and colonization of Lotus ...

Abstract:: ... The Lotus japonicus symbiont Mesorhizobium loti R7A encodes two copies of nodD and here we identify striking differences in Nod factor biosynthesis gene induction by NodD1 and NodD2 both in vitro and in planta. We demonstrate that induction of Nod factor biosynthesis genes is preferentially controlled by NodD1 and NodD2 at specific stages of symbiotic infection. NodD2 is primarily responsible for ...

Abstract:: ... With the original aim of surveying the role of exopolysaccharide (EPS) in Lotus-Mesorhizobium symbiosis, we carried out Tn5 mutagenesis of Mesorhizobium loti and obtained 32 mutants with defects in EPS biosynthesis. One of the mutants, HIA22, formed pseudonodules and failed to fix nitrogen with Lotus japonicus. However, complementation analysis unexpectedly revealed that the potential gene with th ...

Abstract:: ... 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 LjENOD40-2 i ...

Abstract:: ... • Triterpenes are plant secondary metabolites, derived from the cyclization of 2,3-oxidosqualene by oxidosqualene cyclases (OSCs). Here, we investigated the role of lupeol synthase, encoded by OSC3, and its product, lupeol, in developing roots and nodules of the model legume Lotus japonicus. • The expression patterns of OSC3 in different developmental stages of uninfected roots and in roots infect ...
