Association mapping is rapidly becoming the main method for dissecting the genetic
architecture of complex traits in plants. Currently most association mapping studies in plants are …

It has been long known that immigrants from surrounding populations might prevent the
extinction of small populations, a process known as the ‘rescue effect'. This focuses on the …

Association or linkage disequilibrium mapping has become a very popular method for
dissecting the genetic basis of complex traits in plants. The benefits of association mapping, …

Conifers have dominated forests for more than 200 million years and are of huge ecological
and economic importance. Here we present the draft assembly of the 20-gigabase genome …

Populus is an important model organism in forest biology, but levels of nucleotide polymorphisms
and linkage disequilibrium have never been investigated in natural populations. Here I …

We use Wright’s distribution of equilibrium allele frequency to demonstrate that hybrids
between populations interconnected by low to moderate levels of migration can have large …

Segregation distortion is increasingly recognized as a potentially powerful evolutionary force.
This runs counter to the perception that non-Mendelian genes are rare genetic curiosities, …

Although hundreds of plant lineages have independently evolved dioecy (that is, separation
of the sexes), the underlying genetic basis remains largely elusive 1 . Here we show that …

… tremula is a highly polymorphic species (Ingvarsson 2005) it is likely that the observed
deficit of heterozygotes we see at some of the SSR loci is caused by null alleles. We therefore …

… LD (Ingvarsson 2005b). There was also a quite striking excess of low-frequency polymorphisms
in P. tremula (Ingvarsson … in population size (Ingvarsson 2005b). However, the study by …
