Max Planck Institute for Plant Breeding Research

The Max Planck Institute for Plant Breeding Research carries out basic molecular biological research on plants. The goal of the Cologne-based scientists is to improve conventional breeding methods and to develop environmentally-friendly plant protection strategies for crops. They focus mainly on the evolution of plants, their genetic blueprint, their development and their interactions with the environment. How does a plant's immune system react to pests, for example? How does the time of flowering depend on the seasonally changing length of the day? How does the genetic variability of crops affect how they adapt to specific environmental influences? The botanists, geneticists and plant physiologists work both in the laboratory and in greenhouses, searching for the molecular basis of natural diversity, and thus make innovative contributions to plant breeding.

Genes against Drought

MPR 3 /2010 Environment & Climate

In many regions of the world, agriculture is threatened by a lack of water. New plant varieties must thus be developed that are especially resistant to drought.

The infestation of crop plants by pathogens can have devastating consequences for world nutrition. Christiane Gebhardt and her collaborators at the Max Planck Institute for Plant Breeding Research are searching for genes in the potato genome that will make it easier to breed potatoes with disease resistance and other quality traits.

Epigenetic information storage in plants

2018 Krause, Kristin; Coupland, George; Turck, Franziska

Genetics Plant Research

An epigenetic memory determines how strongly genes are expressed. Polycomb Group protein complexes stably shut down genes by compacting the packaging material of DNA. Recent studies in plants showed that two different and short DNA sequences, called teloboxes and RY motifs, are involved in this epigenetic process. Genes that are under epigenetic regulation are enriched in both motifs, often in combination. Specialized transcription factors, which recognize teloboxes and RY motifs, also directly bind to building blocks of the Polycomb Group and thus stabilize the memory of target genes.

To improve crop quality and yield, breeders need to control the fertility of stamens, the male organs that produce pollen within sacs called anthers. For example, it would be ideal to manipulate at will the release of pollen from anthers. However, this firstly requires a detailed understanding of how anther cells themselves activate pollen release. In barley, this activation seems to be triggered by the phytohormone auxin and requires enzymes to separate specific cells from each other to finally open the anthers.

Plant boundary zones initiate development of new meristems

2016 Mulki, Muhammad Aman; Rossmann, Susanne; Theres, Klaus

Plant Research

Boundary zones were previously seen as physical barriers that separate plant tissues and thus allow the development of functional organs. However, recent studies revealed that boundaries, like those between the shoot apical meristem and leaf primordia and those between leaflets, also serve as launching pads for secondary meristem formation and play an important role in determining plant architecture. Interestingly, establishment of boundary zones during shoot branching and complex leaf development is regulated by homologous genes.

Robustness and tunability of the plant immune system

2015 Tsuda, Kenichi; Berens, Matthias L.

Developmental Biology Evolutionary Biology Genetics Plant Research

Plants sense microbial molecules to trigger innate immunity for protection from pathogens. However, microbes have evolved broad virulence factors that interfere with plant immune components. Therefore, immune mechanisms must be robust to cope with microbial perturbations. In addition, since too much immune response is detrimental for plant fitness, plant immune responses need to be tuned. The scientists study how plant immune signaling networks achieve the properties robustness and tunability using molecular genetics, genomics and computational modeling.

Exploring the role of protein post-translational modifications in the regulation of plant metabolism

2014 Finkemeier, Iris

Developmental Biology Evolutionary Biology Genetics Plant Research

Depending on the environmental conditions, plants can rapidly alter their metabolism. Post-translational modification of proteins seems to play key roles during this adaptation. Reversible acetylation of lysine residues in proteins has recently emerged as post-translational modification controlling many important cellular functions beyond transcription. The identification of acetylation sites on metabolic enzymes in plants is a first step to uncover its physiological role in metabolism.
