International Collection of (Vesicular) Arbuscular Mycorrhizal Fungi

The International Collection of (Vesicular) Arbuscular Mycorrhizal Fungi (INVAM) is a globally recognized resource dedicated to the culture, maintenance, and distribution of arbuscular mycorrhizal fungi (AMF) isolates. AMF are obligate symbiotic fungi that form mutually beneficial relationships with the roots of most land plants. These fungi enhance plant nutrient uptake, particularly phosphorus, and contribute to soil health and plant biodiversity.

INVAM serves as a repository for a diverse range of AMF species, allowing researchers, educators, and industries access to well-characterized and authenticated fungal strains. The collection provides living cultures of AMF that can be used in various research applications, including:

• Ecological studies: Investigating the role of AMF in plant communities and ecosystems.
• Agricultural applications: Developing bio-inoculants to improve crop yields and reduce fertilizer use.
• Conservation biology: Using AMF to restore degraded lands and promote plant establishment.
• Taxonomic and phylogenetic studies: Clarifying the evolutionary relationships and diversity of AMF.

INVAM's activities include:

• Isolate Acquisition: Collecting AMF spores from different geographical regions and ecological niches.
• Culture Maintenance: Propagating and maintaining AMF isolates in sterile conditions, typically through single-species pot cultures with suitable host plants.
• Characterization: Identifying and characterizing AMF isolates based on morphological, molecular, and physiological traits.
• Distribution: Providing AMF cultures to researchers and educators worldwide, along with information on their origin, characteristics, and cultivation methods.
• Education and Outreach: Offering workshops, training courses, and online resources to promote understanding and utilization of AMF.

INVAM plays a vital role in advancing our knowledge of AMF and their importance in plant and soil ecosystems. By providing access to well-curated fungal cultures, INVAM contributes to the development of sustainable agricultural practices, conservation efforts, and a deeper understanding of the complex interactions between plants and microbes. It is considered a crucial resource for the global scientific community working on mycorrhizal symbiosis.
