Mitochondrial genotyping of isolates of the arbuscular mycorrhizal fungus "Glomus intraradices" from the isolate collection of the International Bank…

International audience; The culture collection of the International Bank of Glomeromycota (BEG) provides an important service to scientific community and industry by acting as a repository for well-defined AMF isolates which are made available to the public. The most widely-used species has been referred to as "Glomus intraradices", and was recently renamed Rhizophagus irregularis. This species has emerged as a model organism for experimental research and is the subject of the first AMF genome to be sequenced. The only genetic marker that can currently be used to distinguish strains of R. irregularis in field settings is the mitochondrial large subunit (mtLSU). In addition, genetically dist…
Molecular studies of diversity of populations of arbuscular mycorrhizal fungi
2011
National audience; Arbuscular mycorrhiza fungi (AMF) which form a mutualistic symbiosis with most terrestrial plants are not only important for natural ecosystems, but also for agricultural production. The aim of this study is to characterize fungal populations at different geographic scales in order to better understand the processes influencing AMF taxonomic and functional diversity and to determine the environmental factors affecting AMF populations, especially in the context of agricultural management. The mitochondrial large subunit gene of ribosomal RNA will be used as molecular marker to resolve population structure of Rhizophagus irregularis (formerly known as Glomus intraradices). …

Expression of Sorghum bicolor ammonium transporters upon colonization with arbuscular mycorrhizal fungi
2012
Arbuscular mycorrhizal fungi (AMF) are important plant symbionts, trading mineral nutrients beyond the reach of roots, in particular ammonium, in exchange to their host’s photosynthetic products. Sorghum bicolor is one of the world's leading cereal crops, providing food, fibre and fuel across a range of environments and production systems. It has a particular ability to be productive even under strongly adverse conditions, tolerating much more severe drought than most other grain crops. As its genome has recently been sequenced, we have characterized all eight members of the ammonium transporter (AMT) family and studied their expression in different tissues of field-grown plants. While most…
