CYCLOPS, a mediator of symbiotic intracellular accommodation
- K. Yano, S. Yoshida, M. Parniske
- Biology, Environmental ScienceProceedings of the National Academy of Sciences
- 23 December 2008
The results suggest that CYCLOPS forms an ancient, preassembled signal transduction complex with CCaMK that is specifically required for infection, whereas organogenesis likely requires additional yet-to-be identifiedCCaMK interactors or substrates.

A simple model for AUT and nitrate inhibition of nodulation mediated by LjCLE-RS1, -RS2 peptides and the HAR1 receptor-like kinase is proposed.

Identification of hypernodulation genes thus indicates that genes in leguminous plants bearing a close resemblance to CLV1 regulate nodule development systemically, by means of organ–organ communication.
Root-derived CLE glycopeptides control nodulation by direct binding to HAR1 receptor kinase.

It is proposed that CLE-RS glycopeptides are the long sought mobile signals responsible for the initial step of autoregulation of nodulation inLeguminous plants.
Deregulation of a Ca2+/calmodulin-dependent kinase leads to spontaneous nodule development

- Biology, Environmental ScienceNature
- 29 June 2006
This work shows that the complex root-nodule organogenic programme can be genetically deregulated to trigger de novo nodule formation in the absence of rhizobia or exogenous rhizobial signals, and reveals a key regulatory position of CCaMK upstream of all components required for cell-cycle activation.
Genome of an arbuscular mycorrhizal fungus provides insight into the oldest plant symbiosis

The genome of Rhizophagus irregularis provides insight into genes involved in obligate biotrophy and mycorrhizal symbioses and the evolution of an ancient asexual organism, and is of fundamental importance to the field of genome evolution.
The Sulfate Transporter SST1 Is Crucial for Symbiotic Nitrogen Fixation in Lotus japonicus Root Nodules
- L. Krusell, Katja Krause, M. Udvardi

Results suggest that SST1 transports sulfate from the plant cell cytoplasm to the intracellular rhizobia, where the nutrient is essential for protein and cofactor synthesis, including nitrogenase biosynthesis.
NUCLEOPORIN85 Is Required for Calcium Spiking, Fungal and Bacterial Symbioses, and Seed Production in Lotus japonicus

- Environmental Science, BiologyThe Plant Cell Online
- 1 February 2007
Together with symbiotic nucleoporin NUP133, L. japonicus NUP85 might be part of a specific nuclear pore subcomplex that is crucial for fungal and rhizobial colonization and seed production.
Plastid proteins crucial for symbiotic fungal and bacterial entry into plant roots
- H. Imaizumi-Anraku, N. Takeda, M. Hayashi
- Biology, Environmental ScienceNature
- 3 February 2005
Surprisingly, both twin proteins from Lotus japonicus are localized in the plastids of root cells, indicating a previously unrecognized role of this ancient endosymbiont in controlling intracellular symbioses that evolved more recently.
Root, root hair, and symbiotic mutants of the model legume Lotus japonicus.
- M. Kawaguchi, H. Imaizumi-Anraku, S. Akao
- Biology, MedicineMolecular Plant-Microbe Interactions
- 2002
To gain an overview of plant factors controlling nodule number and organogenesis, an extensive screening using model legume Lotus japonicus was carried out and mutant lines maintaining the phenotypic variation were selected and genetically analyzed.
