Molecules boosting plant immunity identified<br /> 
Two studies published in the journal Science by researchers at the Max Planck Institute for Plant Breeding Research in Cologne, Germany in collaboration with colleagues in China have discovered natural cellular molecules that drive critical plant immune responses. These compounds have all the hallmarks of being small messengers tailored by plants to turn on key defense-control hubs. Harnessing these insights may allow scientists and plant breeders to design molecules that make plants, including many important crop species, more resistant to disease. [more]
Differentiating friends from foes in the fungal root microbiome
A collaborative project between researchers has shed light on the fungal genetic determinants that explain why some fungi from the root microbiome can colonize roots and cause disease more efficiently than others.
Host and resident bacteria join forces to control fungi in plant roots<br /> 
Researchers from the Max Planck Institute for Plant Breeding Research (MPIPZ) have discovered that diverse root-colonizing fungi can benefit plants, but only when they are kept in check by the host innate immune system and the bacteria residing in roots. [more]

Of oil, wine and friends, the oldest is the best: root-associated bacteria preferentially colonize their native host-plant roots
An international team of researchers from the Max Planck Institute for Plant Breeding Research and the University of Åarhus in Denmark have discovered that bacteria from the plant microbiota are adapted to their host species. In a newly published study, they show how root-associated bacteria have a competitive advantage when colonizing their native host, which allows them to invade an already established microbiota. [more]
Belowground microbial solutions to aboveground plant problems
Researchers from the Max Planck Institute for Plant Breeding Research (MPIPZ) have discovered that signalling occurring from the response of plant leaves to light, and plant roots to microbes, is integrated along a microbiota-root-shoot axis to boost plant growth when light conditions are suboptimal. [more]
Identity of an induced protein complex linking pathogen-activated immune receptors to rapid mobilization of immunity
Scientists from MPIPZ in collaboration with the Sainsbury Laboratory (UK) find a long sought after complex between two conserved plant-specific protein families that connect pathogen-activated immune complexes to defence outputs. [more]
A plant immune receptor: it takes four to tango

<p>For plant and animal immune systems the similarities go beyond sensing</p>
Max Planck Institute for Plant Breeding Research (MPIPZ) and University of Cologne researcher Takaki Maekawa and colleagues have discovered that plants have independently evolved a family of immune proteins that are strikingly similar to animals. [more]
<p>Hungry plants rely on their associated bacteria to mobilise unavailable iron</p>
Researchers from the Max Planck Institute for Plant Breeding Research have found that, faced with limiting iron, plants direct their microbiota to mobilise this essential nutrient for optimal growth. [more]
Unpacking the two layers of bacterial gene regulation during plant infection
By analysing the different layers of bacterial gene expression during pathogen infection of a plant host, Kenichi Tsuda and colleagues from the Max Planck Institute for Plant Breeding Research in Cologne, Germany and Huazhong Agricultural University in Wuhan, China have revealed new insights into bacterial gene regulation as well as the strategies employed by plants to target key bacterial processes. [more]
<p>Plants from diverse European habitats associate with the same small group of highly abundant microorganisms</p>
A continental-scale census and analysis of root-inhabiting microorganisms reveals that plants across Europe consistently harbour a small group of unexpectedly abundant ‘core’ microorganisms, irrespective of soil conditions and climate. [more]
Plants can skip the middlemen to directly recognize disease-causing fungi
Scientists at the Max Planck Institute for Plant Breeding Research in Cologne have revealed that direct physical associations between plant immune proteins and fungal molecules are widespread during attempted infection. [more]
Linking sensing to signaling during plant immunity
A new study by researchers at the Max Planck Institute for Plant Breeding Research (MPIPZ) in Cologne has revealed that a previously unappreciated structural feature underlies the ability of the plant immune molecule EDS1 to provide a timely defense boost against pathogens. [more]
Leaf age determines the division of labor in plant stress responses
A new study from researchers at the Max Planck Institute for Plant Breeding Research published in the journal PNAS shows that the crosstalk between plant responses to physical and biological stresses varies between young and old leaves to enable optimal plant performance when the two kinds of stress are encountered simultaneously. [more]
