Jean-Michel Ané

About

Dr. Jean-Michel Ané is a professor in the Department of Plant and Agroecosystem Sciences and in the Department of Bacteriology at the University of Wisconsin-Madison. He received his Ph.D. in plant cellular and molecular biology from the University of Toulouse in France. He leads the Ané Lab, which studies beneficial associations between microbes and plants, with a focus on improving the benefits of microbes to crops, particularly biological nitrogen fixation in non-leguminous plants used in agriculture. His research aims to understand how symbiotic associations between plants and microbes develop, including the microbial signals and signaling pathways that control the establishment of plant-microbe symbioses and stimulate plant growth. The lab transfers knowledge gained from model plants such as Medicago truncatula and Brachypodium distachyon to crops like soybean, alfalfa, rice, and maize, to enhance agricultural productivity and sustainability. Dr. Ané's work emphasizes maintaining soil quality, protecting the environment, and reducing costs for food, feed, and biofuel production through plant biotechnology, molecular biology, genetics, and symbiosis research.

• Lipo-chitooligosaccharides as regulatory signals of fungal growth and development

  Nature Communications · 2020 · 109 citations

  Senior authorCorresponding

  Lipo-chitooligosaccharides (LCOs) are signaling molecules produced by rhizobial bacteria that trigger the nodulation process in legumes, and by some fungi that also establish symbiotic relationships with plants, notably the arbuscular and ecto mycorrhizal fungi. Here, we show that many other fungi also produce LCOs. We tested 59 species representing most fungal phyla, and found that 53 species produce LCOs that can be detected by functional assays and/or by mass spectroscopy. LCO treatment affec…

• Shifts in evolutionary lability underlie independent gains and losses of root-nodule symbiosis in a single clade of plants

  Nature Communications · 2024-05-27 · 39 citations

  articleOpen access

  Root nodule symbiosis (RNS) is a complex trait that enables plants to access atmospheric nitrogen converted into usable forms through a mutualistic relationship with soil bacteria. Pinpointing the evolutionary origins of RNS is critical for understanding its genetic basis, but building this evolutionary context is complicated by data limitations and the intermittent presence of RNS in a single clade of ca. 30,000 species of flowering plants, i.e., the nitrogen-fixing clade (NFC). We developed th…

• The single-cell transcriptome program of nodule development cellular lineages in Medicago truncatula

  Cell Reports · 2024-02-01 · 37 citations

  articleOpen access

  Legumes establish a symbiotic relationship with nitrogen-fixing rhizobia by developing nodules. Nodules are modified lateral roots that undergo changes in their cellular development in response to bacteria, but the transcriptional reprogramming that occurs in these root cells remains largely uncharacterized. Here, we describe the cell-type-specific transcriptome response of Medicago truncatula roots to rhizobia during early nodule development in the wild-type genotype Jemalong A17, complemented…

• Synthetic Biology Toolbox for Nitrogen-Fixing Soil Microbes

  ACS Synthetic Biology · 2023-11-21 · 32 citations

  articleOpen access

  The soil environment adjacent to plant roots, termed the rhizosphere, is home to a wide variety of microorganisms that can significantly affect the physiology of nearby plants. Microbes in the rhizosphere can provide nutrients, secrete signaling compounds, and inhibit pathogens. These processes could be manipulated with synthetic biology to enhance the agricultural performance of crops grown for food, energy, or environmental remediation, if methods can be implemented in these nonmodel microbes.…
