Bacterial Carbohydrate Structure Database, which has been developed earlier, is expanded to cover glycans from plants and fungi. Both bacterial and plant and fungal databases share the same ideology: outstanding data quality, easy cross-project integration, and aiming at complete coverage. Search by any combination of structural fragments (incl. residue superclasses), bibliography (incl. abstract and keywords), taxonomy (incl. strains), and NMR signals is allowed. The data are verified against the original publications prior to deposition. The current coverage on plant and fungal glycans includes several thousands of the Carbbank records and data published before 1996 but not deposited in Carbbank. Validation of these data revealed that more than 30% of the Carbbank data contained errors. The erroneous records were corrected, supplemented with missing information, such as NMR spectra, and uploaded to the Plant and Fungal database. Achieving the complete coverage, as in the Bacterial database, is expected in 2014. These carbohydrate databases are freely available at http://csdb.glycoscience.ru.
