Harrison Hall spends a lot of time staring at fungus. A senior in Crop Sciences at the University of Illinois, Hall has worked for two years in a research lab studying the fungus responsible for a devastating wheat disease. For the former IT professional, it’s perhaps an odd passion, but it came naturally after Hall entered the PRECS program through Parkland College and U of I.
Danforth Center scientists and their collaborators improve disease resistance in cassava using an innovative technology called targeted methylation.
Seventy-five percent of North American plants have been following their preferred climates for the past 18,000 years. Georgia Tech researchers introduce climate fidelity as a framework for evaluating plant niche dynamics to assess how well they have done this. While these plants will likely need to continue shifting geographic ranges, they may be challenged to do so due to habit fragmentation and rapidly changing climates.
Widespread tree scorch in the Pacific Northwest that became visible shortly after multiple days of record-setting, triple-digit temperatures in June 2021 was more attributable to heat than to drought conditions, Oregon State University researchers say.

Attempts to discredit human-caused climate change by touting graphs of prehistoric atmospheric carbon dioxide and temperature changes are not something new. Peter Clack has once again tried to make a point that current atmospheric carbon dioxide levels are comparatively low compared to past eras. But just because we're in an advantageous era compared to past eras, it does not negate the cause for alarm concerning our current warming trend.
RUDN biologists with colleagues from Iran and Ireland have found a plant extract that will help fish in aquaculture to more easily survive the rise in temperature due to global warming.
In tropical mountains, the number of insects declines with increasing altitude. This intensifies in high altitudes competition between plant species that specialize in catching insects as an important source of nutrients.
The speed of environmental change is very challenging for wild organisms. When exposed to a new environment individual plants and animals can potentially adjust their biology to better cope with new pressures they are exposed to - this is known as phenotypic plasticity.
A new species of microalgae was found in water from a home aquarium. While analyzing DNA samples taken from the algae, researchers from the University of Tokyo discovered Medakamo hakoo, whose DNA sequence didn’t match any on record.
As a component of moors, mosses are important for climate conservation. They are also gaining increasing significance in biotechnology and the manufacture of biopharmaceuticals.
Michigan State University researchers have solved a puzzle that could help switchgrass realize its full potential as a low-cost, sustainable biofuel crop and curb our dependence on fossil fuels.
Evolution has occurred more rapidly than previously thought in the Chesapeake Bay wetlands, which may decrease the chance that coastal marshes can withstand future sea level rise, researchers at the University of Notre Dame and collaborators demonstrated in a recent publication in Science.
Story tips: Shuffling the load, a reveille for more biomass, designer molecules may help valuable minerals float, ‘T’ molecules huddle around rare earth elements
Nutrients from salmon carcasses can substantively alter the growth and reproduction of plant species in the surrounding habitat, and even cause some flowers to grow bigger and more plentiful, SFU researchers have found.
The Chan Zuckerberg Initiative awarded a two-year grant for Advancing Imaging Through Collaborative Projects to Kirk Czymmek, PhD, director of the Donald Danforth Plant Science Center’s Advanced Bioimaging Laboratory, Michele Darrow of Rosalind Franklin Institute, and Paul Verkade of the University of Bristol, along with an international team of eight additional scientists.
The North American Plant Phenotyping Network (NAPPN), a partner of the International Plant Phenotyping Network (IPPN), will host its annual conference at the Donald Danforth Plant Science Center February 13–17.
Recent experiments have shown that the loss of species from a plant community can reduce ecosystem functions and services such as productivity, carbon storage and soil health.
It's often assumed that island plant and animal populations are just the simple, fragile cousins of those on the mainland.
Tropical forests are crucial for sucking up carbon dioxide from the atmosphere. But they’re also subject to intense storms that can cause “windthrow” – the uprooting or breaking of trees. A new study finds that more extreme thunderstorms from climate change will likely cause a greater number of large windthrow events in the Amazon, which could impact the rainforest's ability to serve as a carbon sink.
Bees may be at risk from exposure to glyphosate – an active ingredient in some of the EU’s most commonly used weedkillers – via contaminated wildflower nectar, according to new research from Trinity and DCU scientists.
To tackle the climate crisis, biodiversity loss, and pollution, humanity will need to move to a circular economy, where all resources are recycled.
Heat and drought are the utmost limiting abiotic factors which pose a major threat to food security and agricultural production and are exacerbated by ‘extreme and rapid’ climate change, according to a new paper in CABI Reviews.
RUDN University biologists have discovered a new type of pathogenic fungus that infects potatoes and leads to massive crop loss. Fungi in this genus were previously known to be harmful to potatoes and other plants, but this species was considered harmless.
Plant biochemists at Brookhaven National Laboratory have discovered a new level of regulation in the biochemical “machinery” that plants use to convert organic carbon derived from photosynthesis into a range of ring-shaped aromatic molecules. The research suggests new strategies for controlling plant biochemistry for agricultural and industrial applications.
Lignin, the complex polymer that gives plants their structural integrity, makes them difficult to break down and creates challenges for the creation of biochemicals and bioproducts. Building blocks that are present in small amounts in the lignin of the bioenergy crop poplar are valuable platform chemicals that are easy to “clip-off” during plant deconstruction. Scientists engineered a new type of poplar to have more of a specific building block in its lignin and less lignin overall. This results in wood that is easier to deconstruct and more valuable as a bioproduct raw material.
In the Arctic, plant community type strongly impacts how energy is exchanged between the land and atmosphere.
Despite recent, torrential rains, most of Southern California remains in a drought.

In many ways, Madagascar is a biologist’s dream, a real-life experiment in how isolation on an island can spark evolution.
RUDN University agronomists have studied the thermodynamics of hydrogels, which must absorb water from the air and hold it in the ground to prevent evaporation. It turned out that this approach is unlikely to help save agriculture from drought - hydrogels retain water too well and give it poorly.
A new study led by researchers at The Australian National University (ANU) has shown that ecosystems in western parts of southeastern Australia – including western Victoria and western Tasmania – may be most at risk of feeling the impacts of climate change in the coming decades.
A new study identifies the genetic underpinnings for why broccoli heads become abnormal when it’s hot, providing insight into effects of climate-induced warming for all crops and pointing the way for breeding heat-resistant new varieties.
Despite some hesitation about gene-edited foods, taste trumps everything, according to a Washington State University-led survey of U.S. consumers.
With the world’s population topping 8 billion last year, it’s clear that humans have achieved a unique status in Earth’s history. We are the only creature that dominate all other organisms on the planet, from animals and fungi to plants and microbes.
DOE funding allows researchers to gain closer look into plant-microbe symbioses.
A RUDN University biologist and colleagues from Iran have found bacteria that can become a potential biological drug against a pest fungus that infects rice. Unlike chemical fungicides, such a bio-agent is harmless to the environment and does not lead to the formation of biological resistance.
When an outbreak of sylvatic plague decimated black-tailed prairie dog numbers in the Thunder Basin National Grassland in 2017, researchers saw an opportunity for a “natural experiment” to explore the impact of the rodents’ die-off on the plants and other wildlife in that area of northeast Wyoming.
