In temperate and boreal ecosystems, seasonal cycles of growth and dormancy allow perennial
plants to adapt to winter conditions. We show, in hybrid aspen trees, that photoperiodic …

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 …

While several studies have investigated general properties of the genetic architecture of
natural variation in gene expression, few of these have considered natural, outbreeding …

The Populus genus is one of the major plant model systems, but genomic resources have
thus far primarily been available for poplar species, and primarily Populus trichocarpa (Torr. & …

Background Evolutionary theory suggests that males and females may evolve sexually
dimorphic phenotypic and biochemical traits concordant with each sex having different optimal …

Background Secretory Carrier-Associated Membrane Proteins (SCAMPs) are highly conserved
32–38 kDa proteins that are involved in membrane trafficking. A systems approach was …

Seed maturation is the developmental process that prepares the embryo for the desiccated
waiting period before germination. It is associated with a series of physiological changes …

With the need to increase plant productivity, one of the challenges plant scientists are facing
is to identify genes that play a role in beneficial plant traits. Moreover, even when such …

Leaf shape is a defining feature of how we recognize and classify plant species. Although
there is extensive variation in leaf shape within many species, few studies have disentangled …

The signalling pathways that control seasonal modulation of carbon metabolism in perennial
plants are poorly understood. Using genetic, metabolic and natural variation approaches, …
