Arbuscular mycorrhizal (AM) fungi facilitate plant uptake of mineral nutrients and draw organic nutrients from the plant. Organic nutrients are thought to be supplied primarily in the form of sugars. Here we show that the AM fungus Rhizophagus irregu

Every year, infection of wheat by the fungus Fusarium graminearum results in losses of ∼28 million metric tons of wheat grain (1), valued at $5.6 billion. The fungus reduces yields but also contaminates harvests with trichothecene toxins such as de

Wheat scab, also known as Fusarium head blight, can significantly dent harvests. And the toxins released by the fungus Fusarium graminearum remain in grain, which must either be discarded or blended with uninfected grain. Researchers have now found a

Plant Microbiota Some soils show a remarkable ability to suppress disease caused by plant pathogens, an ability that is attributed to plant-associated microbiota. Carrion et al. investigated the role of endophytes, the intimate microbial community fo

Plant Symbioses Plants benefit from widespread symbiosis with arbuscular mycorrhizal fungi. This symbiosis between plant and fungus aids plants in capturing mineral and micronutrients from the soil. Gutjahr et al. have now identified a component of a

Plant Science Plants can use small RNAs (sRNAs) to interfere with virulence factor gene expression in pathogens. Cai et al. show that the small mustard plant Arabidopsis shuttles defensive sRNAs into the necrotrophic fungus Botrytis cinerea via extra

Plant Science When the rice blast fungus enters a rice cell, the plasma membrane stays intact, so the rice cell remains viable. The fungus then moves to adjacent cells via plasmodesmata, the plant's intercellular channels. Sakulkoo et al. used a chem

Antifungal saponins occur in many plant species and may provide a preformed chemical barrier to attack by phytopathogenic fungi. Some fungal pathogens can enzymatically detoxify host plant saponins, which suggests that saponin detoxification may dete

Aging Some species of fungi and plants can live for a thousand years or more. How do these species avoid harmful mutations over these long time spans? In a Perspective, Aanen highlights a recent study that reports extremely low genetic variation in a

Some flowering plants mimic the scent and appearance of mushroom fruiting bodies. Fungi may also mimic flowers. In addition, infection of plants by certain fungi can direct the plant to develop nonfunctional floral-like structures that nonetheless pr
