Conflicting selection on floral traits
Floral traits attracting pollinators may also attract seed predators; however, evidence for conflicting selection on such traits remains scarce. One could expect that such selection generated

Spore settling velocity to assess moss dispersal rates
The settling velocity of diaspores is a key parameter influencing dispersal ability in wind-dispersed plants but remains largely undocumented in bryophytes. Zanatta et al. measured

Organellar phylogenomics of Sphagnum
Sphagnum (peatmoss) is rapidly developing as a model for ecological genomics research. Twenty or more species of Sphagnum often co-exist within peatlands and sort themselves

Root system architecture of oilseed rape under two phosphate availabilities
One important adaptation of plants to Phosphorus (P) deficiency is to alter root system architecture (RSA) to increase P acquisition from the soil, but soil-based

A genetic linkage map of perennial ryegrass (Lolium perenne) based on GBS
Genetic linkage maps remain very important tools for gene discovery in many plant species. Whilst several genetic maps exist for perennial ryegrass, it has been difficult

Sexual and asexual reproduction in a mycoheterotrophic orchid
Sexual reproduction is common within Orchidaceae, though apomixis does occur in some genera allowing them to produce seeds that are clones of the mother. The reproductive

Floral scent chemistry in the orchid genus Gongora
Floral scent is a key component of pollinator attraction and its chemistry modulates pollinator behavior and the formation of plant-pollinator networks. Neotropical Gongora orchids exhibit
