Chinese aspen with a dynamic Quaternary evolutionary history
Populus adenopoda (Salicaceae), the Chinese aspen, occurs in the subtropical China region. Fen et al. report a genetic survey to reveal that it survived in multiple

Thresholds for the onset of xylogenesis in juniper
A mismatch between the thresholds of temperature and moisture for the onset of xylogenesis may increase forest vulnerability in semi-arid areas under forecasted warmer and drier conditions.

Wheat genetic resources: Progress and challenges in genomics
Exploiting wild relatives of wheat for improvement of its cultivated form dates back to 1869; since then it has impacted most areas of wheat pre-breeding

Exploring trees in 3D using Terrestrial Laser Scanner
Tree form assessments using the Terrestrial Laser Scanner (TLS) have increased during recent years, but many existing methods are limited to small-sized trees. Based on

The meiotic behaviour of doubled-diploid and the origin of triploid limes
Lime is the only Citrus horticultural group including natural polyploid cultivars (C. latifolia and C. aurantiifolia) in addition to diploid species. Rouiss et al. uses cytogenetic

Linking invasive–native plant competition to foraging and nutrient conditions
The effects of the competition between invasive and native plants have rarely been linked with root foraging behaviour. Chen et al. performed a competition experiment with

Floral nectar tubes in Pelargonium
Co-evolutionary matches between lengths of floral nectar tubes and pollinator proboscises is associated with speciation in several lineages, including Pelargonium (Geraniaceae), a genus renowned for

Diversification of Dioon in the Mexican transition zone
The Mexican transition zone originated from the overlap of the Nearctic and the Neotropical biotas. By analysing the genetic variation within the cycad genus Dioon, a

Two-stage patterning dynamics in conifer cotyledon morphogenesis
Conifers form a single whorl of multiple cotyledons (embryonic leaves), unlike monocots and dicots. Polar transport of the hormone auxin affects outgrowth of distinct cotyledons, but

Pollen limitation and reproductive assurance in a fragmented landscape
Humans have transformed landscapes, leaving remnant habitats embedded within a complex matrix. For many plants, the associated factors of decreased population size and increased land-use

Rapid ecological diversification of the Eurasian goldenrod complex
The Solidago virgaurea complex shows remarkable morphological and ecological diversity in Japan. Phylogeographic analysis suggested the multiple expansions from the Eurasian continent into the archipelago via
