“…It has been proposed that the LysM-type cell-wall binding domain binds non-covalently to peptidoglycan of various gram-positive bacteria [12]. The LysM motif has also been found in a number of eukaryotic proteins [10], and it was recently demonstrated that LysM domains are involved in recognition of symbiotic bacteria by the roots of plants [13][14][15]. In L. lactis, following secretion of the AcmA cell-wall hydrolase, the PA directs the protein to the cell wall.…”

“…Here, we detected a chitinase (predgene 000254), a family of enzymes known for their role in resistance to pathogens (Punja and Zhang 1993;Grover 2012). We also discovered a gene involved in recognition of symbiotic bacteria (LysM receptor-like kinase, predgene 002974) which notably enables the model legume Lotus japonicus to recognize its bacterial symbiont Radutoiu et al 2003;Ryals et al 2008). Symbiotic nitrogen fixation is a specific feature of legumes, and nutrient availability largely varies across microhabitats (Ferry et al 2010).…”

Plant populations are able to undergo very localized adaptive processes, that allow continuous populations to adapt to divergent habitats in spite of recurrent gene flow. Here, we carried out a genome scan for selection through whole-genome sequencing of pools of populations, sampled according to a nested sampling design, to evaluate microgeographic adaptation in the hyperdominant Amazonian tree Eperua falcata Aubl. (Fabaceae). A high-coverage genomic resource of ~250 Mb was assembled de novo and annotated, leading to 32 789 predicted genes. 97 062 bi-allelic SNPs were detected in 25 803 contigs were detected, and a custom Bayesian model we implemented to uncover candidate genomic targets of divergent selection.A set of 290 'divergence' outlier SNPs was detected at the regional scale (between study sites), while 185 SNPs located in the vicinity of 106 protein-coding genes were detected as replicated outliers between microhabitats within regions. These genes possibly underlie ecologically important phenotypes and tend to indicate that adaptation to microgeographic habitat patchiness would affect genomic regions involved in a variety of physiological processes, among which plant response to stress (for e.g., oxidative stress, hypoxia and metal toxicity) and biotic interactions. Identification of genomic targets of microgeographic adaptation in the Neotropics supports the hypothesis -frequently raised at the community level -that local adaptation would be a key driver of ecological diversification, probably operating across multiple spatial scales, from large-(i.e. regional) to microgeographic-(i.e. landscape) scales.

“…Mutations in En 1314 and En 1282 soybeans were found in the NFR1 gene, which is known to be responsible for a LysM-type receptor kinase for Nod factor recognition (Radutoiu et al, 2003 Masaki Hayashi (National Institute of Agrobiological Sciences, Tsukuba, Japan), personal communication). A mutation in En 6500 was found in the GmNARK (NTS1) gene (Nishimura et al, 2002), which mediates systemic autoregulation of nodulation (Searle et al, 2003), and Sakukei 4 is a descendant with a hypernodulating phenotype that was derived from En 6500 (Matsunami et al, 2004).…”

The diversity of stem-associated bacteria of non-nodulated (Nod À ), wild-type nodulated (Nod þ ) and hypernodulated (Nod þ þ ) soybeans were evaluated by clone library analyses of the 16S ribosomal RNA gene. Soybeans were dressed with standard nitrogen (SN) fertilization (15 kg N ha -1 ) and heavy nitrogen (HN) fertilization (615 kg N ha -1 ). The relative abundance of Alphaproteobacteria in Nod þ soybeans (66%) was smaller than that in Nod À and Nod þ þ soybeans (75-76%) under SN fertilization, whereas that of Gammaproteobacteria showed the opposite pattern (23% in Nod þ and 12-16% in Nod À and Nod þ þ soybeans). Principal coordinate analysis showed that the bacterial communities of Nod À and Nod þ þ soybeans were more similar to each other than to that of Nod þ soybeans under SN fertilization. HN fertilization increased the relative abundance of Gammaproteobacteria in all nodulation phenotypes (33-57%) and caused drastic shifts of the bacterial community. The clustering analyses identified a subset of operational taxonomic units (OTUs) at the species level in Alpha-and Gammaproteobacteria responding to both the nodulation phenotypes and nitrogen fertilization levels. Meanwhile, the abundance of Betaproteobacteria was relatively constant in all libraries constructed under these environmental conditions. The relative abundances of two OTUs in Alphaproteobacteria (Aurantimonas sp. and Methylobacterium sp.) were especially sensitive to nodulation phenotype and were drastically decreased under HN fertilization. These results suggested that a subpopulation of proteobacteria in soybeans is controlled in a similar manner through both the regulation systems of plant-rhizobia symbiosis and the nitrogen signaling pathway in plants.
