Floral mimicry of Faboideae in an Australian orchid
While there is increasing recognition of floral mimicry in plants, there are few cases where any explanatory mechanism is confirmed. Scaccabarozzi et al. test for pollination

Male reproductive success and floral trait evolution in animal-pollinated plants
More than 85% of flowering plant species require the services of foraging animal pollinators to transfer male gametes (pollen) to stigmas of potential mates. The vast

Multiple parallel dispersal events and mosaic genetic structure in Dactylorhiza
Orchids have minute seeds and can disperse over long distances. Hedrén et al. use genetic markers to track how the marsh orchid Dactylorhiza majalis ssp. lapponica

Unmasking cryptic biodiversity in polyploids
Up to one-quarter of flowering plant species may have escaped recognition due to processes such as autopolyploidy-whole genome duplication events where polyploids may be

The loss of genetic diversity threatens the last Afro-Macaronesian subtropical forests
Subtropical African forests are on the verge of extinction due to a long history of exploitation. Considered sanctuaries of exceptional biodiversity, they shelter many endemic and

Genome-wide identification of long non-coding RNA targets of the tomato MADS box transcription factor RIN and function analysis
In recent years, increasing numbers of long non-coding RNAs (lncRNAs) have been identified in humans, animals and plants, and several of them have been shown

Genetic differentiation among varieties of a Neotropical savanna tree
The Neotropical savanna fruiting tree species, Hancornia speciosa (Apocynaceae) has high social and economic importance in Brazil. Originally classified as six botanical varieties, more recently only

The impact of asexual and sexual reproduction on spatial genetic structure in Marchantia
Sexual reproduction requires close proximity of mates, but ensures genetic variation in the local population. Although independent of cross-pollination, asexual reproduction can however, reduce genetic

Amazon ant-plant postpones ant defenses to escape from flooding
Growing in flooding environments is a high risk strategy for plants. Izzo et al. show that in order to colonize the margins of the Juruena River,

Adaptation of ecological strategies to climate within species
In Grime’s C-S-R strategy model, plant ecological strategies vary between ruderals (R), stress-tolerators (S) and competitors (C). These variations are assumed to

Functional traits in endemism hotspots and refugia
Refugia are island-like habitats that are linked to long-term environmental stability and, as a result, high endemism. Conservation of refugia and endemism hotspots should

Root hair abundance impacts cadmium accumulation in Arabidopsis thaliana shoots
Root hairs increase the contact area of roots with soil and thereby enhance the capacity for solute uptake. The strict hair/non-hair pattern of Arabidopsis
