MaarjAM
Web-based database for studies on the diversity of arbuscular mycorrhizal fungi (Glomeromycota)

The MaarjAM database has reached version 0.8.1 beta and is still in the process of development. Therefore it is possible that for short periods of time MaarjAM will not be accessible or fully functional. We will do our best to minimize the time taken to repair known errors. All fixes are timed for late evening, local time (UTC + 2), but people in different time-zones may experience short downtimes during working hours.

MaarjAM is a web-based database containing Glomeromycota DNA sequence data that originate from ecological studies based on “environmental samples” or taxonomic investigations based on cultured fungi. It has the following goals:

  • to bring together published data from studies applying molecular methods to the natural diversity and taxonomy of Glomeromycota;
  • to reclassify existing sequence data and create “virtual taxa” on the basis of a novel phylogenetic analysis. Species (binomial) and “molecular taxa” classifications are also indicated where available;
  • to enable browsing and searching in relation to virtual taxa classification, original species/molecular taxa classifications, and ecological/biogeographic variables, including geographical location, biome and host plant.

Several facets of MaarjAM, such as browsing and simple searches, are made publicly available through this web page. A log-in service is available to advanced users wishing to make use of the following features: DNA sequence and biogeographic data exports, complex searches and submitting data to MaarjAM. If you would like to make use of the log-in service, please contact the database administrator (see Contacts).
