Scientists once gravitated toward thinking that non-legumes, which are not infected by rhizobia, just werent capable of receiving the NOD factor signal. But, a less popular theory guessed that plants like corn do receive the NOD factor signal but interpret it differently or have a problem with the mechanistic pathway.. Stacey said figuring out which is happening is like fixing a motion-detecting light.. "If you walk into a room and the light doesnt turn on, either the motion detector is broken or theres a breakdown of the electrical circuit between the detector and the light bulb," Stacey said. "The analogy in a corn plant would be that it either doesnt recognize the signal or recognizes the signal but lacks the ability to couple it with downstream developmental effects.". Staceys lab set out to determine which was true.. Corn, soybean, tomato and Arabidopsis were treated with bacterial flagellin, a protein known to cause a strong immune response, and also received doses of the NOD factor. ...

Ascochyta (Mycosphaerella) blight on cultivated peas is primarily caused by infection through asexual spores (pycnospores) of Mycosphaerella pinodes (Berk. et Blox.) Vestergren [recently renamed Peyronellaea pinodes (Berk. & A. Bloxam) Aveskamp, Gruyter & Verkley]. Using a recently developed model pathosystem involving Medicago truncatula and M. pinodes strain OMP-1, we examined the histology and ultrastructure of early infection events and fungal development including penetration by appressoria, vegetative growth of infection hyphae, and host responses. On the susceptible ecotype R108-1, pycnospores germinated and grew over the surface of the epidermis, then formed an appressoria and penetrated the cuticle. Beneath the cuticle, the infection peg expanded into a hyphae that grew within the outer wall of the epidermis. Subsequently, the hyphae penetrated down within mesophyll cells and proliferated vigorously, eventually, forming asexual fruiting bodies (pycnidia). In contrast, successful penetration and

[9], Ane, Jean-Michel [10]. Medicago truncatula DMI1 localizes to the nuclear envelope and regulates Nod factor-induced calcium spiking.. In addition to establishing symbiotic relationships with arbuscular mycorrhizal fungi, legumes also enter into a nitrogen-fixing symbiosis with rhizobial bacteria that result in the formation of root nodules. Several genes required for the development of these symbioses have been cloned in model legumes. Among them, the M. truncatula DMI1 protein shares strong homologies with prokaryotic ion channels such as MthK. Two DMI1 homologs in L. japonicus, named CASTOR and POLLUX, have been localized in plastids. However our studies ...

The Auxin Response Factor (ARF) family of transcription factors is an important regulator of environmental response and symbiotic nodulation in the legume Medicago truncatula. While previous studies have identified members of this family, a recent spurt in gene expression data coupled with genome update and reannotation calls for a reassessment of the prevalence of ARF genes and their interaction networks in M. truncatula. We performed a comprehensive analysis of the M. truncatula genome and transcriptome that entailed search for novel ARF genes and the co-expression networks. Our investigation revealed 8 novel M. truncatula ARF (MtARF) genes, of the total 22 identified, and uncovered novel gene co-expression networks as well. Furthermore, the topological clustering and single enrichment analysis of several network models revealed the roles of individual members of the MtARF family in nitrogen regulation, nodule initiation, and post-embryonic development through a specialized protein packaging and

The molecular dissection of plant growth and development in model plants such as Arabidopsis has largely relied on genetic approaches involving the isolation and subsequent characterization of mutants affected in specific biological processes. The utility of this approach now encompasses virtually every facet of plant biology, beginning from plant embryogenesis to flowering and senescence, and plant-pathogen interactions.. Despite the general validity of Arabidopsis as a model plant species, several biological processes do not occur in Arabidopsis and are better studied in other species. Examples of such species-processes combinations include tomato for climacteric fruit ripening, maize for regulation of seed storage protein biosynthesis, and legumes for study of plant symbiotic interactions with nitrogen-fixing bacteria (collectively termed rhizobia) and fungal symbionts (collectively termed mycorrhizae).. In contrast to the large impact plant mutants have had on a molecular dissection of plant ...
Nodule primordia induced by rhizobial glycan mutants often remain uninfected. To identify processes involved in infection and organogenesis we used forward genetics to identify plant genes involved in perception and responses to bacterial glycans. To dissect the mechanisms underlying the negative plant responses to the Mesorhizobium loti R7AexoU and ML001cep mutants, a screen for genetic suppressors of the nodulation phenotypes was performed on a chemically mutagenized Lotus population. Two mutant lines formed infected nitrogen-fixing pink nodules, while five mutant lines developed uninfected large white nodules, presumably altered in processes controlling organogenesis. Genetic mapping identified a mutation in the cytokinin receptor Lhk1 resulting in an alanine to valine substitution adjacent to a coiled-coil motif in the juxta-membrane region of LHK1. This results in a spontaneous nodulation phenotype and increased ethylene production. The allele was renamed snf5, and segregation studies of ...

The original aim of this study was to develop EST-SSR markers and linkage maps for molecular genetics analysis in white clover. We achieved this by generating 1973 WCS markers and an integrated map with 1743 loci. WGS markers were designed based on the accumulated 7982 non-redundant white clover EST sequences. Although the number of accumulated EST sequences was limited, the proportion of KOG functional categories represented by the accumulated EST sequences was comparable to the proportion predicted in the genomes of Arabidopsis, L. japonicas, and rice. In addition, the distribution of the identified SSR motifs in the accumulated white clover EST sequences was basically similar to the distribution found in the genomes of other legume species, such as L. japonicas (Sato et al. 2008). Therefore, no specific bias should be observed in the accumulated white clover EST sequences.. In parallel, we discovered the existence of LD across linkage groups on the T17-349-specific map. Although the ...
Bothalia: African Biodiveristy & Conservation is published by AOSIS for the South African National Biodiversity Institute (SANBI) and aims to disseminate knowledge, information and innovative approaches that promote and enhanve the wise use and management of biodiversity in order to sustain the systems and species that support and benefit the people of Africa. The journal was previously publishd as Bothalia, and had served the South African botanical community since 1921. However the expande mandate of SANBI necessitated a broader scope for the journal, and in 2017, the subtitle, African Biodiversity & Conservation was added to reflect this change.
JCVI hosts the M. truncatula genome sequence and annotation in three forms: a Tripal database, JBrowse and an instance of InterMine named MedicMine. These databases also form part of a larger consortium of legume databases known as the Legume Federation (legumefederation.org). The Legume Federation is a joint project with USDA-ARS-Iowa State and the National Center for Genome Resources. Together, these three centers house genomic, genetic and phenotypic (QTL) data for around 10 legume crop species including soybean, common bean, peanut, chickpea, clover, lupin and others.

Ensifer meliloti WSM1022 is an aerobic, motile, Gram-negative, non-spore-forming rod that can exist as a soil saprophyte or as a legume microsymbiont of Medicago. WSM1022 was isolated in 1987 from a nodule recovered from the roots of the annual Medicago orbicularis growing on the Cyclades Island of Naxos in Greece. WSM1022 is highly effective at fixing nitrogen with M. truncatula and other annual species such as M. tornata and M. littoralis and is also highly effective with the perennial M. sativa (alfalfa or lucerne). In common with other characterized E. meliloti strains, WSM1022 will nodulate but fixes poorly with M. polymorpha and M. sphaerocarpos and does not nodulate M. murex. Here we describe the features of E. meliloti WSM1022, together with genome sequence information and its annotation. The 6,649,661 bp high-quality-draft genome is arranged into 121 scaffolds of 125 contigs containing 6,323 protein-coding genes and 75 RNA-only encoding genes, and is one of 100 rhizobial genomes ...
Macrophomina phaseolina is a soil-borne fungal pathogen that causes a disease commonly known as charcoal rot. Currently, there is not an effective method for controlling the disease, because knowledge about the pathogen, the development of the disease and how it interacts with the plant host is limited. Therefore, a study is proposed to investigate the interactions between M. phaseolina and the plant species Medicago truncatula using a molecular genetics approach where the host genes involved in the disease development will be identified. We will first conduct a genetic screen in a mutant population of M. truncatula and look for strains that have altered susceptibility to M. phaseolina. We will then identify the genes that are involved in host-pathogen interactions ...

Regulatory networks controling the initiation and development of an arbuscular mycorrhiza (AM) symbiosis involve the interaction of different classes of transcription factors (TFs), primarily belonging to the NF-Y, GRAS, AP2/ERF, and Myb categories. To identify protein-protein interactions amongst selected, AM-activated TFs as well as between those TFs and their target promoters, yeast-2-hybrid (Y2H) and yeast-1-hybrid (Y1H) experiments are performed. To verify such protein-protein interactions in planta, split-YFP fusions of selected, AM-activated TFs are expressed in transgenic Medicago truncatula roots or Nicotiana benthamiana leaves.. ...
