Evolution of salt resistant rose species in European coastal areas
Survival at saline habitats - A challenge for the genus Rosa
The
adaption on saline habitats led to the evolution of salt tolerance
plants. The coastal areas of the North Sea and the Baltic Sea are
influenced by the selective factor salt stress. Wild roses are no
typical halophytes but the native species Rosa spinosissima and Rosa mollisoccur
on coastal areas with high salinity levels, whereas other north
European rose species avoid these areas. The Japanese Rose (Rosa rugosa),
a neophytic and invasive rose originating from eastern Asia, displaces
native rose species from their habitats. One explanation for the
invasive success of Rosa rugosa is its very well developed salt
tolerance. Up to now only a few studies exist, which investigate the
morphological, anatomical and physiological basics of salt tolerance in
ornamental roses, but studies on wild roses are lacking. In this project
we want to unravel the mechanisms of salt tolerance in six wild rose
species to understand the evolutionary success of rose species in
coastal areas.
