Signal honesty and cost of pollinator-rewards in Dalechampia
Most species of Dalechampia vines (Euphorbiaceae) attract bee pollinators with terpenoid resins secreted by a gland-like structure in the inflorescence. Pélabon et al. study the

Pollen water status, development and functioning (Invited Review)
The male gametophyte developmental program can be divided into five phases, which differ in relation to the environment and pollen hydration state: the microsporogenesis phase; the

Parental environment and seed response to karrikinolide
Seeds from different populations of the same species often show distinct germination responses to the smoke-derived chemical karrikinolide (KAR1), thus limiting its potential for use

Contemporary gene flow in Arabis alpina
Gene flow is important in counteracting the divergence of populations but also in spreading genes among populations. Buehler et al. describe the effective mating system and

Flower development in Balsaminaceae
Balsaminaceae consist of two genera, the monospecific Hydrocera and its species-rich sister Impatiens; however, morphological support for the current molecular phylogeny of Balsaminaceae is low.
