Seed dormancy regulates germination response to smoke and temperature in a rhizomatous evergreen perennial

Seed dormancy status regulates the response of seeds to environmental cues that can trigger germination. Anigozanthos flavidus (Haemodoraceae) produces seeds with morphophysiological dormancy that are...

Seed dormancy and germination vary within and between species of milkweeds

Declines in pollinator populations and monarch butterflies require restoration of habitats with the plants and floral resources that support them. Monarch butterflies in particular...

Risky Business For Heather

A new study finds increased temperature requirements for germination of heather (Calluna vulgaris) seeds from colder climates.

Prediction of seed germination time for wild grapevine

Thermal thresholds for seed dormancy release and germination are important tools for predicting germination timing. Orrù et al. study germination in seeds of Vitis vinifera...

How do you get more DNA down a pollen tube?

A common event for flowering plants is whole genome duplication (WGD), where a plant gets extra chromosomes. It’s often studied in mature...

Simulating the effects of local adaptation and life history on the ability of plants to track climate shifts

Local adaptation is common but not universal in plants and results from the interplay of gene flow with natural selection. Gene flow...

What creates Gentiana diversity in mountains?

The Qinghai-Tibetan Plateau (QTP) is extremely rich in species, but why? One recent explanation is the mountain‐geobiodiversity hypothesis (MGH) by Mosbrugger et...
