Atlas identifies genome regions that regulate plant cell identity

Posted on May 21, 2021 by Amy McDermott

Zoom in on the leaf of a corn plant, and you’ll find a patchwork of about 20 different cell types. A recent study, published in Cell, provides an atlas of critical genomic regions that control cell identity in six different … Continue reading →

Agricultural spray could quickly deliver advantageous genes to crops mid-growing season

Posted on March 12, 2021 by Carolyn Beans

Plant breeders are masters of genome tuning, spending years developing crops with the genes to resist disease, drought, and pests. Now, a team of industry and academic researchers in Germany and the United Kingdom has developed a viral vector technology … Continue reading →

How an animal’s teeth can reveal where it’s been

Posted on February 5, 2021 by Stephen Ornes

A careful measurement of isotope ratios in animals’ teeth could offer a new way to closely track their movements, according to a recent study that showed how the approach would work in Mongolian sheep and goat herds. Tooth enamel … Continue reading →

Interdisciplinary study brings a humanist perspective to research on land use change

Posted on October 23, 2020 by Amy McDermott

Decades ago, Brazil’s northeastern State of Bahia produced much of the world’s cocoa for chocolate. Most farms grew their cacao trees interspersed with other native trees, in dense agricultural forests. Children played at the forest edges. Today those children are … Continue reading →

Satellite monitoring may help preserve the Chesapeake Bay by improving farming practices

Posted on August 7, 2020 by Lynne Peeples

Restoring the Chesapeake Bay, the nation’s largest estuary, has for decades proven to be a fraught enterprise, beset by the interests of researchers, farmers, anglers, multiple governments, and a host of others. A new approach, recently reported in Remote … Continue reading →

Country-level assessment hides big variations in soy’s carbon footprint

Posted on May 29, 2020 by Jyoti Madhusoodanan

Analysts usually estimate a crop’s carbon footprint based on country-level factors. But that formulation isn’t adequate, according to a new analysis of soy exports from Brazil. Published in Global Environmental Change, the study tracked soy from specific production sites in … Continue reading →

Variation in a single gene increases plant yield in groups but not in pairs

Posted on March 27, 2020 by Carolyn Beans

Groups of diverse plant species often produce more seeds than monocultures. But whether plants ramp up yield in response to genetically distinct, direct neighbors, as opposed to a broader neighborhood of diverse plants, remains an open question in ecology. “It’s … Continue reading →

Rice gene could make “green revolution” plants greener by cutting back on fertilizer

Posted on March 6, 2020 by Carolyn Beans

The green revolution was launched, in large part, with rather squat plants. In the 1960s, farmers began using semidwarf varieties of wheat and rice that produced many grain-bearing branches known as tillers. When farmers added nitrogen fertilizer, the plants gained … Continue reading →

Potentially key gene has big role in natural variation of chloroplast size

Posted on November 22, 2019 by Amy McDermott

Worldwide populations of Arabidopsis thaliana all have the same genes, but they vary in many traits, including the size of their chloroplasts. A recent study in Plant Physiology identified one of the genes, FtsZ2-2, contributing to the natural variation in … Continue reading →

Intensive agriculture changes the soil microbiome

Posted on November 8, 2019 by Amy McDermott

California rice farms dot the Sacramento Valley, converting native swampland into flooded paddies. The farms change California’s landscape both above ground and below it. A recent study shows in detail how rice plants shape the soil microbiome into a distinctive … Continue reading →

Common features of domestic animals suggest caveats to evolutionary theory

Posted on October 11, 2019 by Natasha Gilbert

White patches on fur coats, floppy ears, and curly tails are some of the traits frequently seen in domesticated animals. A group of researchers has now put forth a theory as to why these traits so often evolve in association … Continue reading →
