Flowering is the most crucial act that plants undergo, as the fruits of such labor include crops on which the world depends, and seeds from which the next generation grows. While classic experiments have demonstrated that plants are able to adjust the timing of their flowering in response to environmental ...

Mild mannered though they seem, plants are extremely competitive, especially when it comes to getting their fair share of sunlight. Whether a forest or a farm, where plants grow a battle wages for the sun's rays.

Have you ever wondered why stems grow upwards and roots downwards? Why plants always seem to turn towards the light and climbing plants run up the trellis rather than down?

In order to survive, plants should take up neither too many nor too few minerals from the soil. New insights into how they operate this critical balance have now been determined. The researchers discovered novel functions of the metal-binding molecule nicotianamine.

Global warming may initially make the grass greener, but not for long, according to new research results. The findings show that plants may thrive in the early stages of a warming environment but then begin to deteriorate quickly.

Lawrence LeBlond for Redorbit.comA leading climate change scientist at NASA is urging the United Kingdom to cease building coal-fired power plants, and is calling for a worldwide tax on all carbon emissions, to tackle the climate change fight head-on, reports BBC Scotland.Dr. James Hansen said, in an interview with BBC ...

The importation of plants from around the world has become a major industry in the United States, valued at more than $500 billion. According to a new study that economic boon has also had devastating effects on the environment. Researchers found that almost 70 percent of the most damaging non-native ...

Plants can use the sense of touch to fight off fungal infections and insects, new research shows. The study finds the first evidence that plant resistance -- activated by the plant hormone jasmonate -- is triggered by touch. In a study of Arabidopsis thaliana, biochemists found that touched plants had ...

Biologists aim to predict which plant species will escape extinction from climate change. Droughts are worsening around the world, which poses a great challenge to plants in gardens and forests. Scientists have debated for more than a century how to predict which species are most vulnerable.

The color and scent of flowers and their perception by pollinator insects are believed to have evolved in the course of mutual adaptation. However, an evolutionary biologist from the University of Zurich has now proved that this is not the case with the arum family at least, which evolved its ...

The color and scent of flowers and their perception by pollinator insects are believed to have evolved in the course of mutual adaptation. However, an evolutionary biologist has now demonstrated that this is not the case with the arum family at least, which evolved its scent analogously to the pre-existing ...

Researchers have unraveled the action mechanism of the main plant hormone that regulates the development of stomata. This breakthrough has important implications for environmental research and for the protection of plants against disease and stress.
