Digital reconstruction gets to the root of 400-million-year-old plant

Posted on September 3, 2021 by David Adam

Researchers have managed to reconstruct the detailed 3-D structure of a fossilized plant more than 400 million years old. The ancient leafy organism, a relative of today’s clubmosses, grew in the Early Devonian era—a crucial time for the development of … Continue reading →

Drought causes lasting changes to the rice root microbiome

Posted on August 6, 2021 by Carolyn Beans

Beneficial microbes living in and around a crop’s roots could be powerful allies in the fight to keep plants alive through droughts, especially as climate change worsens. But before scientists can harness these microbial partners to make crops more resilient, … Continue reading →

Prion-like protein acts as water sensor in seeds

Posted on July 26, 2021 by Jyoti Madhusoodanan

The sprouting of a seed is clearly a crucial stage in a plant’s life. Yet one part of the process has long been shrouded in mystery: How do seeds know when there’s enough water to germinate? Researchers recently reported the … Continue reading →

Transgenic switchgrass cleans up contamination from military explosives

Posted on May 14, 2021 by Carolyn Beans

At military sites in the United States and across the globe, routine live-fire trainings produce a downpour of an explosive known as RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine). A synthetic chemical, RDX can threaten human health, damaging the nervous system if inhaled or ingested. … Continue reading →

Venus flytrap mechanism could shed light on how plants sense touch

Posted on April 3, 2021 by David Adam

Labelled by Charles Darwin as a “most wonderful” plant, the Venus flytrap is more than a carnivorous curiosity. The rapid closing of its leaves when brushed by prey offers researchers a way to investigate how plants sense their environment through … Continue reading →

Plants sense temperature with help of elegant protein

Posted on September 18, 2020 by Amy McDermott

How plants sense temperature is a longstanding and little-understood question. Researchers have discovered some of the mechanisms involved. A recent study in Nature adds a new mechanism—among the first in which the biophysical behavior of a single protein regulates the … Continue reading →

Genome of “mile-a-minute weed” hints at the secrets to its invasive success

Posted on February 7, 2020 by Amber Dance

The weedy vine Mikania micrantha, originally from Central and South America, has become a worldwide menace. Thus far, it’s spread to tropical climes in China and Southeast Asia, Australia, and islands of the Pacific and Indian Oceans, as well as … Continue reading →

Unlocking a mystery of seed development promises fatter, oilier oilseeds

Posted on August 30, 2019 by Amy McDermott

The canola cooking oil lining supermarket shelves comes from the seeds of Brassica napus, a weedy-looking plant in the mustard family. Farmers of this crop understandably want varieties that yield big, oily seeds. A recent study in The Plant Cell … Continue reading →

Nitrogen-fixing bacteria talk to soybean roots via tiny RNAs, suggesting new avenue to improve yields

Posted on August 2, 2019 by Amber Dance

In order for soybean plants to get their necessary dose of nitrogen, they partner with bacteria called rhizobia, which can convert atmospheric nitrogen into organic forms the plant can use. But scientists don’t have the full picture of what facilitates … Continue reading →

Journal Club: Understanding how a plant makes a hook could someday improve crops

Posted on April 12, 2019 by Amber Dance

This spring, as the first shoots of new plants emerge from the soil, many are bent over in a hook. This simple act protects the fragile stem tip and leaves as the sprout pokes up through the dirt. But how … Continue reading →

Journal club: A simple model to help identify which species might become invasive

Posted on March 11, 2019 by Natasha Gilbert

Invasive species are a major driver of global biodiversity loss. Now researchers have developed a simple model that can quickly predict which species are likely to become established outside their native environment. The team recently reported in the Proceedings of … Continue reading →
