Protein Discovery Reveals How Fungi Bypasses Plant Defenses

A research team led by the U.S. Department of Agriculture's Agricultural Research Service and Washington State University (WSU) found that the Sclerotinia sclerotiorum fungus uses a protein to bypass the natural defenses of plants and cause extensive rot in hundreds of broad leaf plant varieties. According to Weidong Chen, »

A New Wearable Technology -- For Plants

Plants can't speak up when they are thirsty. And visual signs, such as shriveling or browning leaves, don't start until most of their water is gone. To detect water loss earlier, researchers reporting in ACS Applied Materials & Interfaces have created a wearable sensor for plant leaves. The system wirelessly »

Protein Discovery Reveals Mechanisms of Nitrogen Assimilation in Plants

A research group at Tohoku University has discovered the protein that inhibits the formation of organic nitrogen compounds in plants. The protein could potentially be used to improve plant growth, biomass production, and crop yields. Nitrogen is important to humans and plants. Plants use nitrate or ammonium in the environment »

Bacteria that Kills Fungus Affecting Sugarcane Yields Discovered

A study conducted by scientists at the Brazilian Center for Research in Energy and Materials (CNPEM) has discovered that three strains of Pseudomonas bacteria can inhibit growth, and even cause the death, of the fungus responsible for pineapple sett rot, a disease that attacks sugarcane. The three strains of Pseudomonas »

Genome Sequence of Forage Grass Now Available

Researchers from the Brazilian Agricultural Research Corporation (Embrapa) have produced the genome sequence of signal grass (Urochloa ruziziensis), one of the most used forage grasses in tropical agriculture. Embrapa researcher Marco Pessoa Filho explains that U. ruziziensis has evolutionary proximity to other Urochloa species most used in cultivated tropical pastures »

Climate Change: Heat Stress for Cattle

Climate change poses a potentially devastating economic threat to low-income cattle farmers in poor countries due to increasing heat stress on the animals. Globally, by the end of this century, those producers may face financial losses between $15 and $40 billion annually. Farmers in tropical regions -- including large parts »

Researchers Analyze Maize's Fertilizer Uptake to Improve Yields

Researchers from Guangdong Academy of Science in China used a new technique called single cell RNA-sequencing (scRNA-seq) to identify and describe the major cell types in the root-tip of maize as well as the developmental pathways and genes involved in various functions. Their study is published in The Crop Journal. »

Hardy Wild Grass Could Help Save the World's Bread

An international team of researchers led by the John Innes Centre, The Sainsbury Laboratory, and the University of Minnesota have identified the stem rust resistance gene from a wild goat grass species. The researchers found the gene in Aegilops sharonensis, a wild relative of wheat found in Israel and southern »

An Aromatic Tomato Could Be Looming -- A La Heirloom Varieties

You can scarcely find a tasty, heirloom tomato in the grocery store. But University of Florida scientists helped discover a way to enhance tomato smell and taste. Breeding efforts over the last half-century have emphasized traits that are important to producers -- yield, disease resistance, appearance and post-harvest shelf life »
