In a study appearing in Science, researchers show that the pesticide imidacloprid, which has been sold in the U.S. since 1994, disrupts bumblebee (Bombus impatiens) nest behavior, causing reduced growth in exposed colonies.
With robotics, computers and advanced genetics, researchers at the University of California, Davis, and Cold Spring Harbor Laboratory have established a core set of genes that help plants metabolize nitrogen, the key to plant growth and crop yield.
In a study appearing in Cell Host & Microbe, UC Davis graduate student Neeraj Lal, Professors Savithramma Dinesh-Kumar and Andrew J Fisher and their colleagues reveal the versatility of plants’ molecular defenses. The findings provide a strategic map revealing how plants allocate resources and have the potential to help bolster crop immune systems and improve their development and growth.
In a paper appearing in PLOS Biology, Joseph Edwards, ’17 Ph.D. in Plant Biology, Professor Venkatesan Sundaresan, Departments of Plant Biology and Plant Sciences and their colleagues tracked root microbiome shifts throughout the life-cycle of rice (Oryza sativa). The research could help inform the design of agricultural probiotics by introducing age-appropriate microbes that promote traits like nutrient efficiency, strong roots and increased growth rates in rice plants.
In a study appearing in Genome Biology and Evolution, Assistant Professor Santiago Ramirez, Department of Evolution and Ecology, and postdoctoral researcher Julie Cridland provide a genetic snapshot of the state’s honey bee populations, defining how the species has changed over the past 105 years.
The Asian citrus psyllid, the most devastating threat to the worldwide citrus industry, may have met its match.
In a ground-breaking discovery encompassing six years of research, an international team of scientists led by UC Davis chemical ecologist Walter Leal announced they've identified the sex pheromone of the pest, which feeds on citrus and transmits the bacteria that causes the deadly citrus greening disease known as Huanglongbing (HLB).
In a review article published in Nature: Science of Food, Professor Raymond Rodriguez and his colleagues explore the relationship between diet and brain health, proposing a framework to understand the body’s “food-brain axis,” the intersection of diet and the formation of new brain cells. Rodriguez’s aim is to provide researchers with a dietary roadmap to help prevent cognitive decline.
How did plants develop photosynthesis? The story is really nothing more than a tale of biological thievery.
Publishing in The Plant Cell, Lagarias and his colleagues found that a pigment called biliverdin is essential to light-induced chlorophyll production in the alga. This discovery is helping scientists understand why diverse algae retain these pigments, although many lack phytochromes.
