Recent 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 کاملRecent Y chromosome divergence despite ancient origin of dioecy in poplars (Populus).
All species of the genus Populus (poplar, aspen) are dioecious, suggesting an ancient origin of this trait. Despite some empirical counter examples, theory suggests that nonrecombining sex-linked regions should quickly spread, eventually becoming heteromorphic chromosomes. In contrast, we show using whole-genome scans that the sex-associated region in Populus trichocarpa is small and much young...
متن کاملPolymorphism 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...
