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 کاملMolecular and cytogenetic analysis of repetitive DNA in pea (pisum sativum L.).
A set of pea DNA sequences representing the most abundant genomic repeats was obtained by combining several approaches. Dispersed repeats were isolated by screening a short-insert genomic library using genomic DNA as a probe. Thirty-two clones ranging from 149 to 2961 bp in size and from 1,000 to 39,000/lC in their copy number were sequenced and further characterized. Fourteen clones were ident...
متن کاملEndogenous Gibberellins in Elongating Shoots of Clones of Salix dasyclados and Salix viminalis.
Elongating shoots of rapidly growing clones of Salix viminalis L. (clone 683-4) and Salix dasyclados Wimm. (clone 908) harvested in early August were analyzed for endogenous gibberellins (GA). Distribution of GA-like activity, determined by Tan-ginbozu dwarf rice microdrop bioassay after reverse phase C(18) high performance chromatography, was similar for both species. For S. dasyclados, combin...
متن کاملJunk DNA - repetitive sequences
Eukaryote and also human DNA contains large portion of noncoding sequences. As for the coding DNA, the noncoding DNA may be unique or in more identical or similar copies. DNA sequences with high copy numbers are then called repetitive sequences. If the copies of a sequence motif lie adjacent to each other in a block, or an array, we are speaking about tandem repeats, the repetitive sequences di...
متن کاملAssociation mapping in Salix viminalis L. (Salicaceae) – identification of candidate genes associated with growth and phenology
Willow species (Salix) are important as short-rotation biomass crops for bioenergy, which creates a demand for faster genetic improvement and breeding through deployment of molecular marker-assisted selection (MAS). To find markers associated with important adaptive traits, such as growth and phenology, for use in MAS, we genetically dissected the trait variation of a Salix viminalis (L.) popul...
