When 200 natural accessions of the model plant Arabidopsis thaliana grown in a nitrate-enriched medium were compared, one observation stood out: some accessions formed significantly longer lateral ...

Scientists have developed a toolbox of transcriptional regulators for plants and show that they can be used to construct synthetic genetic circuits that predictably modify root growth. Their work is ...

Plants don't just respond to light and water, they also run on an internal daily timekeeper known as the circadian clock. Researchers have now discovered that the plant circadian clock can regulate ...

Scientists have determined how the well-known plant hormone ethylene is crucial in controlling the angle at which roots grow. The findings can be used to engineer plants and crops that withstand the ...

A biological mechanism familiar to people who fast helps plant roots grow strong. The discovery provides an answer to a long-unanswered question and a deeper understanding of the 'mouths' of plants ...
