Polymorphism and Divergence in Two Willow Species, Salix viminalis L. and Salix schwerinii E. Wolf
We investigated species divergence, present and past gene flow, levels of nucleotide polymorphism, and linkage disequilibrium in two willows from the plant genus Salix. Salix belongs together with Populus to the Salicaceae family; however, most population genetic studies of Salicaceae have been performed in Populus, the model genus in forest biology. Here we present a study on two closely relat...
متن کاملFluoride Uptake in Hydroponic Culture by Different Clones of Basket Willow, Salix Viminalis L
This study was conducted to determine the relationship in Hoagland’s hydroponic culture medium between fluoride at levels of 190, 380, 570, and 950 mg F/ L and the ability of different clones of basket willow (Salix viminalis L.: ‘Bjor’, ‘Jorr’, and ‘Tora’) to take up F. After 14 days of exposure to NaF in the medium, the roots and leaves of seedlings of these three varieties of basket willow w...
متن کاملRecent Sex Chromosome Divergence despite Ancient Dioecy in the Willow Salix viminalis
Sex chromosomes can evolve when recombination is halted between a pair of chromosomes, and this can lead to degeneration of the sex-limited chromosome. In the early stages of differentiation sex chromosomes are homomorphic, and even though homomorphic sex chromosomes are very common throughout animals and plants, we know little about the evolutionary forces shaping these types of sex chromosome...
متن کاملCadmium and copper uptake and translocation in five willow (Salix L.) species.
The efficacy for phytoremediation of five willow species was tested by experimental copper and cadmium uptake in a greenhouse hydroponic system. Five treatments included two concentrations (5 and 25 microM for each metal) and a control. Metal concentrations in solution as well as solution uptake were monitored. Metal resistance was assessed through effects on the dry weight of roots and shoots....
متن کاملCyanide acclimation in willow (Salix babylonica L.), a prospect for the phytoremediation of cyanide
Phytoremediation counts as a major method for future which essentially needs resistance to contaminating agents. We pretreated the plants (Salix babylonica, as a model plant in phytoremediation of polluted waters) by sodium cyanide (0, 3 and 5 mg CN- L-1) to induce resistance with regard to acclimation and then examined their resistance to higher concentrations of cyanide. Accordingly, some of ...
