Immune defense as key for plants conquering land<br /> 
A new study, led by Hirofumi Nakagami at the Max Planck Institute for Plant Breeding Research in Cologne, Germany, demonstrates that one of the two branches of plant immunity was likely to have evolved early during the establishment of plants on dry land. This insight into prehistoric plant immunity may have implications for breeding more resistant plant species.

Structural insights illuminate the arms race between crop plants and fungal pathogens<br /> 
Scientists from the Max Planck Institute for Plant Breeding Research shed light on how harmful fungi evade recognition by their plant hosts and aid infection.

A guide through the genome
Plants show enormous variety in traits relevant to breeding, such as plant height, yield and resistance to pests. One of the greatest challenges in modern plant research is to identify the differences in genetic information that are responsible for this variation. A research team led by the "Crop Yield" working group at the Institute for Molecular Physiology at Heinrich Heine University Düsseldorf (HHU) and at Max Planck Institute for Plant Breeding Research in Cologne (MPIPZ), together with the Carnegie Institution of Science at Stanford, has now developed a method to identify precisely these special differences in genetic information. Using the example of maize, they demonstrate the great potential of their method in the journal Genome Biology and present regions in the maize genome that may help to increase yields and resistance to pests during breeding.

Keeping competitors away drives colonization success in the plant microbiota
Scientists from the Max Planck Institute for Plant Breeding Research, in Cologne, in collaboration with an international team of researchers, have identified natural chemical strategies that bacteria use to keep competitors at bay and successfully proliferate on plants. The study is now published in the journal PNAS.

Scientists provide evidence for new theory of genetic recombination<br /> 
New findings from researchers at the Max Planck Institute for Plant Breeding Research in Cologne, Germany, suggest an explanation for the century-old mystery of how chromosome recombination is regulated during sexual reproduction. Their findings are published in the journal Nature Communications.

Structure of wheat immune protein resolved – important tool in the battle for food security
Scientists from the Max Planck Institute for Plant Breeding Research and the University of Cologne in Germany together with colleagues from China have unravelled how wheat protects itself from a deadly pathogen. Their findings, published in the journal Nature, could be harnessed to make important crop species more resistant to disease. [more]
Resolving target-gene specificity via protein–protein interactions<br /> 
A fundamental topic in plant development is how proteins function together in regulatory networks to coregulate the activity of specific target genes. A collaboration between researchers in the groups of George Coupland and Jijie Chai from the Max-Planck Institute for Plant Breeding Research and the University of Cologne has elucidated an elegant mechanism for how a particular protein–protein interaction cooperatively targets genes in Arabidopsis by affecting DNA conformation. The findings, published in Nature Plants, has wider implications for how transcription factors can achieve regulatory specificity in other developmental contexts.

Speeding up evolution at genome-level by alternative chromosome configuration<br /> 
A research team led by André Marques at the Max Planck Institute for Plant Breeding Research in Cologne, Germany, has uncovered the profound effects of an atypical mode of chromosome arrangement on genome organization and evolution. Their findings are published in the journal Cell. [more]
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]
A stiff polymer called lignin (stained red) is deposited in a precise pattern in the cell walls of exploding seed pods. Researchers identified three laccase enzymes required to form this lignin. No lignin forms in the cell wall when all three genes are knocked out by CRISPR/Cas9 gene editing
Researchers identify the genes controlling the mechanical structure of exploding seed pods [more]
A two-step adaptive walk in the wild<br /> 
New research in plants that colonized the base of an active stratovolcano reveals that two simple molecular steps rewired nutrient transport, enabling adaptation.
