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 →

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 →

Journal Club: Seedbanks, meant to safeguard key plant species, need to enhance their diversity

Posted on February 1, 2019 by Amy McDermott

Humanity’s last hope could someday rest on a humble seed, tucked away in the cool and dark of a collection. Seed collections, called seedbanks or seed genebanks, store millions of grains, nuts, and kernels in baggies and plastic bins, meant … Continue reading →

Journal Club: Single gene mutation may boost recombination and help produce better crops

Posted on December 7, 2018 by Jessica P. Johnson

As climate change and population growth threaten to destabilize global food security, plant breeders are ramping up efforts to create better, more productive crops. But in order to introduce new traits, breeding techniques typically rely on rare genetic recombination events … Continue reading →

Journal Club: Protein vs protein, study comprehensively compares the environmental impacts of livestock and seafood

Posted on July 20, 2018 by Marcus Woo

The most environmentally friendly protein sources include clams, sardines, and cod. Not surprisingly, beef has the worst environmental impact. Somewhat surprisingly, farmed salmon is relatively innocuous; but catfish is not. These are the conclusions of a recent study that compares … Continue reading →
