Description

Linum tenue is an annual herbaceous species which ranges in height from 30 to 150 cm and has distylous actinomorphic yellow flowers with fivefold symmetry. The two floral morphs differ reciprocally in the length of their styles and stamens, with the longer organs protruding slightly from the corolla, which has nectaries at its base (Foroozani et al. 2023). L. tenue exhibits heteromorphic self-incompatibility, meaning that only crosses between and not within morphs are compatible (Murray, 1986; Gutiérrez-Valencia et al. 2024). The native range of L. tenue ranges from the southwest Iberian peninsula into north Africa.

The distyly supergene of L. tenue consists of an ~260 kb region on scaffold 10 of the genome assembly of L. tenue (Gutiérrez-Valencia et al. 2022). At the L. tenue distyly supergene, short-styled thrum morph individuals are hemizygous, harboring only the longer, dominant allele, whereas long-styled pin morph individuals are homozygous for the shorter, recessive allele.
