Shoot-applied MeJA suppresses root nodulation in Lotus japonicus.
To maintain a symbiotic balance, leguminous plants have a systemic regulatory system called autoregulation of nodulation (AUT). Since AUT is schematically similar to systemic resistance found in plant-pathogen interactions, we examined the effects of methyl jasmonate (MeJA) or methyl salicylate (MeSA) on nodulation in Lotus japonicus. Shoot-applied MeJA strongly suppressed nodulation in the wil...
متن کاملInvasion of Lotus japonicus root hairless 1 by Mesorhizobium loti involves the nodulation factor-dependent induction of root hairs.
In many legumes, including Lotus japonicus and Medicago truncatula, susceptible root hairs are the primary sites for the initial signal perception and physical contact between the host plant and the compatible nitrogen-fixing bacteria that leads to the initiation of root invasion and nodule organogenesis. However, diverse mechanisms of nodulation have been described in a variety of legume speci...
متن کامل'That DAT' gene that causes dystonia-parkinsonism: broadening the phenotype.
Dopamine transporter (DAT) deficiency, a recessive disorder due to mutations in the encoding SLC63 gene, was first described by Kurian et al. (2009, 2011). The typical phenotype originally reported was infantile dystonia-parkinsonism with a characteristic metabolic profile in the CSF, namely a raised homovanillic acid: 5-hydroxyindoleacetic acid (HVA:5-HIAA) ratio, usually in excess of 4.0. Pre...
متن کاملTranscriptome Profiling of Lotus japonicus Roots During Arbuscular Mycorrhiza Development and Comparison with that of Nodulation
To better understand the molecular responses of plants to arbuscular mycorrhizal (AM) fungi, we analyzed the differential gene expression patterns of Lotus japonicus, a model legume, with the aid of a large-scale cDNA macroarray. Experiments were carried out considering the effects of contaminating microorganisms in the soil inoculants. When the colonization by AM fungi, i.e. Glomus mosseae and...
متن کاملRoot Isoflavonoid Response to Grafting between Wild-Type and Nodulation-Mutant Soybean Plants.
It was previously reported that the hypernodulating soybean (Glycine max [L.] Merr.) mutants, derived from the cultivar Williams, had higher root concentration of isoflavonoid compounds (daidzein, genistein, and coumestrol) than did Williams at 9 to 12 days after inoculation with Bradyrhizobium japonicum. These compounds are known inducers of nod genes in B. japonicum and may be involved in sub...
