Association 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...
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 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 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 کاملDevelopment of Genetic Markers Linked to Straighthead Resistance through Fine Mapping in Rice (Oryza sativa L.)
Straighthead, a physiological disorder characterized by sterile florets and distorted spikelets, causes significant yield losses in rice, and occurs in many countries. The current control method of draining paddies early in the season stresses plants, is costly, and wastes water. Development of resistant cultivar is regarded as the most efficient way for its control. We mapped a QTL for straigh...
