Nodulation Data in GRIN Taxonomy.

Root nodules that host rhizobial bacteria capable of fixing atmospheric nitrogen are widely recognized from members of Fabaceae. However, not all genera or species of legumes nodulate, and several genera form stem rather than root nodules. Literature reports of the presence or absence of nodules span well over a century and have been published in many different sources. The Germplasm Resources Information Network (GRIN) Taxonomy database includes a set of approximately 7,000 citations of these reports from Cannabaceae, Chenopodiaceae, Fabaceae, Krameriaceae, and Zygophyllaceae. After a five-year absence, the data are publicly searchable on the GRIN website again. Families, or genera and species, can be queried by confirmed (positive) or unconfirmed (negative) nodulation, independently or in combination with native distribution. Query results are displayed in a table that can be exported in .csv or Microsoft Excel format, with columns for the taxon, positive or negative report, and supporting citation. Distribution data for the returned taxa can also be exported. Many older literature reports use scientific names that are now treated as synonyms (e.g., Phanera as Bauhinia), so the searches also return the currently accepted name used in GRIN Taxonomy. The nodulation data set is an important resource for researchers worldwide who study nitrogen fixation in plant communities.
