Aim The distribution range of Lactuca serriola, a species native to the summer-dry mediterranean climate, has expanded northwards during the last 250 years. This paper assesses the influence of climate on the range expansion of this species and highlights the importance of anthropogenic disturbance to its spread. Location Central and Northern Europe. ...

Hybridization rates between lettuce (Lactuca sativa) and its wild relative (L. serriola) under field conditions

D'Andrea, Luigi ; Felber, François ; Guadagnuolo, Roberto

In: Environmental Biosafety Research, 2008, vol. 7, p. 61-71

Hybridization and introgression between crops and wild relatives may have important evolutionary and ecological consequences such as gene swamping or increased invasiveness. In the present study, we investigated hybridization under field conditions between crop lettuce (Lactuca sativa) and its wild relative prickly lettuce (L. serriola), two cross-compatible, predominantly...
