In findings that elucidate Mendel’s 19th C work, gene triggers asexual births in dandelion

Historians have long debated why the ground-breaking hereditability experiments of Gregor Mendel languished, largely unnoticed for decades. His experience with the humble hawkweed probably played a role. Despite Mendel’s best efforts, the common flowering plant refused to breed in the … Continue reading

Stem cell niche within plant callus tissue drives organ regeneration

Proper plant growth in tissue culture experiments typically depends on one crucial step: the plant’s ability to form a clump of pluripotent cells that can then regenerate root, stem, and other organs. This cluster of cells, known as a callus, … Continue reading

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

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

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

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

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

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

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

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

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

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
