Dry Days Trigger Leaves to Send a Surprising Growth Signal Telling Roots to Keep Growing

科学家们已经发现了一种新的分子signalling pathway, triggered when leaves are exposed to low humidity, that ensures plant roots keep growing towards water. A new study has found that when the leaves of a plant are exposed to dry air (low ...

A Roadmap for Gene Regulation in Plants

For the first time, researchers have developed a genome-scale way to map the regulatory role of transcription factors, proteins that play a key role in gene expression and determining a plant's physiological traits. Their work reveals unprecedented insights into gene regulatory networks and ...

'Shoebox' Satellites Help Scientists Understand Trees and Global Warming

As scientists try to understand the effect of climate on trees, advances in imaging technology are helping them see both the whole forest and every individual tree. High-resolution images taken by cubesats, small, shoebox-sized devices launched into low Earth orbit, are helping environmental ...

Plant Extracts Used by Indigenous People Hold Promise in Treatment of Ataxia

Researchers have discovered that extracts from plants used by the Kwakwaka'wakw First Nations peoples in their traditional botanical medicine practices are able to rescue the function of ion channel proteins carrying mutations that cause human ...
