The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches. BLAST can be used to infer functional and evolutionary relationships between sequences as well as help identify members of gene families.

The Information System Genetic Resources (GENRES) offers information about rare tree species in Germany. These are based on the results of nationally surveys - supported by BMEL - using standardized methodologies to preserve genetic resources of rare and endangered tree species (Black Poplar, Common Yew, Downy Oak, Elm species, Field Maple, Green Alder and Grey Alder, Service Tree, Wild Apple, Wild Cherry, Wild Pear and Wild Service Tree). GENRES is hosted by the Information- and Coordination Centre for Biological Diversity at the BLE.
