Leontodon longirostris Raw sequence reads

Leaves from 7 to 20 plants (mean = 12) of L. longirostris were collected at 21 localities following several south-to-north transects across the Iberian Peninsula, resulting in a total sample size of 248 individuals. An additional sample from a distinct population in northeastern Iberia was used to generate the genome draft. Finally, twenty individuals of the close relative L. saxatilis were sampled from two localities in northern Iberia to be used as outgroup. High quality genomic DNA was isolated from 50 to 100 mg of dry leaf material using the DNeasy Plant Mini Kit (Qiagen, Hilden, Germany) following standard protocols.
