Shifts in phenology influence synchrony of flowering plants and their pollinators along an elevation gradient

Oikos, EarlyView.
Climatic conditions alter the phenology of species, which may threaten the synchrony of biotic interactions. However, how phenological synchrony across entire communities of plants and their pollinators responds to varying environmental conditions remains poorly understood.

Effects of Sucrose, Boric Acid, pH, and Incubation Time on in Vitro Germination of Pollen and Tube Growth of Chinese fir (Cunnighamial lanceolata L.)

Forests, 2019
In vitro pollen germination provides a novel approach and strategy to accelerate genetic improvement of tree breeding. Studies about pollen germination and tube growth of Chinese fir are limited.

Wheat breeding approaches for designing wheat to thrive in a warmer world

PLANTS, PEOPLE, PLANET, EarlyView.
Wheat is a vital food crop, accounting for approximately 20% of daily calories and protein consumed worldwide. However, modern‐day wheat is under pressure from global change. The improvement rate of wheat yields is not keeping up with the demand of our growing population. Furthermore, abiotic and biotic stressors are becoming more prevalent. This paper

Intraspecific divergence in floral-tube length promotes asymmetric pollen movement and reproductive isolation.

New Phytologist, 2019
The causative link between phenotypic divergence and reproductive isolation is an important but poorly understood part of ecological speciation. We studied the effects of floral-tube length variation on pollen placement/receipt positions and reproductive

Range‐wide sampling reveals cryptic lineages but largely conserved mycorrhizal associations in the Japanese fairy lantern Thismia kobensis

PLANTS, PEOPLE, PLANET, EarlyView.
The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.

Genomic structure and ex situ conservation of the North American grapevine Vitis labrusca

PLANTS, PEOPLE, PLANET, EarlyView.
The North American wild grapevine species Vitis labrusca is an important source of disease resistance and climate resilience traits for breeding new grapevine cultivars. To ensure its continued use in breeding, V. labrusca must be accurately identified and genetically diverse material must be conserved.

Speciation with gene flow

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

The pistil as a traffic light: Yellow‐to‐red color change likely influences pollinator visitation patterns in Saxifraga fortunei (Saxifragaceae)

PLANTS, PEOPLE, PLANET, EarlyView.
Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...

Pollen tube incompatibility reaction on the stigma in selfpollinated Sinapis alba L.

Acta Societatis Botanicorum Poloniae, 2014
After selfpollination of Sinapis alba L. pollen tubes growth is inhibited on the stigma. The pollen grains germinate 3-4 hours after pollination. The pollen give rise to one or more pollen tubes. They grow along the papillae.
