Genotypic instability is commonly observed in plants derived from tissue culture and is at least partly due to in vitro-induced stress. In this work, the issues of whether genetic instability induced by in vitro stress varies among families and if genetic instability influences the adaptation to in vitro conditions and embryo development have been addressed. By comparing the stability of four v...
Crosses between three distinct species in Nicotiana are comparatively rare, only nine having appeared in the literature on this genus. The one here reported upon, (rustica Xpaniculata) x Langsdor i , as well as (rustics X Tabacum) Xpaniculata, and (rustica X paniculata) XgZutinosa, was produced in Europe many years ago (EAST 1928) but has not been studied much since. In 1930 KOSTOFF also descri...
The expected and already observed increment in frequency of extreme climatic events may result in severe vegetation shifts. However, stabilizing mechanisms promoting community resilience can buffer the lasting impact of extreme events. The present work analyzes the resilience of a Mediterranean mountain ecosystem after an extreme drought in 2005, examining shoot-growth and needle-length resista...
Stilbenes, as important secondary metabolites of grapevine, represent central phytoalexins and therefore constitute an important element of basal immunity. In this study, potential genetic variation in Vitis vinifera ssp. sylvestris, the ancestor of cultivated grapevine, was sought with respect to their output of stilbenes and potential use for resistance breeding. Considerable variation in sti...

Crop-to-wild gene flow can reduce the fitness and genetic integrity of wild species. Malus sylvestris, the European crab-apple fruit tree in particular, is threatened by the disappearance of its habitat and by gene flow from its domesticated relative, Malus domestica. With the aims of evaluating threats for M. sylvestris and of formulating recommendations for its conservation, we studied here, ...
BACKGROUND AND AIMS Differential responses of closely related species to submergence can provide insight into the evolution and mechanisms of submergence tolerance. Several traits of two wetland species from habitats with contrasting flooding regimes, Rorippa amphibia and Rorippa sylvestris, as well as F(1) hybrid Rorippa × anceps were analysed to unravel mechanisms underlying submergence toler...
