''. ''Silene'' species have also been used to study speciation, host-pathogen interactions, biological species invasions, adaptation to heavy-metal-contaminated soils, metapopulation genetics, and organelle genome evolution. Notably, some members of the genus ''Silene'' hold the distinction of harboring the largest mitochondrial genomes ever identified.

Taxonomy

''Silene'' was originally described by

Linnaeus Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming o ...

When treated as a distinct genus, it can often be differentiated by the number of flower styles (five in ''Lychnis' and three in ''Silene''), the number of teeth of the seed capsule (five in ''Lychnis' and six in ''Silene''), and by the sticky stems of ''Lychnis''.
