Database

Database of published chromosome numbers and ploidy-level estimates of the tribe Alysseae is presented, together with the revised generic concept and the list of accepted names and their synonyms, to reflect the most recent taxonomic and phylogenetic studies in Alysseae. The tribe encompasses 24 genera and 277 species. Chromosome numbers and/or ploidy levels are known for 171 out of 297 recognised taxa. Of these, 95 (55.6%) taxa are diploids, 43 (25.1%) are polyploids, and 33 (19.3%) involve both diploids and polyploids. The most common base chromosome number in the tribe is x = 8 and less frequent is x = 7. The highest variation in base chromosome numbers (x = 7, 8, 11, 15) is found in the genus Hormathophylla. The database will be continuously updated.
