Digital technologies in the field

Agricultural scientist Prof. Anne-Katrin Mahlein is a pioneer in the field of sensing and imaging plant diseases.

Help for stressed-out cells in a crisis

The figure shows two root tips of thale cress, Arabidopsis thaliana, which was used as a model plant in the study. The cells contain a biosensor (roGFP2iL) in the endoplasmic reticulum (ER) which reads the ambient redox status and indicates reductive stress in the right-hand root.

The big watchdog on the field

the robot and other technologies enable plants to be observed, analyzed, better understood and given targeted treatment. The device helps researchers to record key parameters such as plant growth, soil conditions, biodiversity and the atmosphere.

Plants convert their phosphate(Pi) status into InsP8 (signaling molecule controlling phosphate acquisition)

ITPK1 plays a key role in this process by generating or removing the precursor of InsP8 according to phosphate-dependent changes in ATP.

Seven-day-old barley roots of mutant egt2

It grows strictly downwards (hypergravitropic).

For comparison, the root without the egt2 mutation

It grows outwards, opening up a larger volume of soil in search for nutrients.

A genomic gene cluster

of the corn smut fungus Ustilago maydis suppresses plant immune defense in maize. In reference to the "sisterly" division of tasks as effectors and the clustered occurrence in the genome, the genes were named after the Pleiades, the nymphs originating from Greek mythology and the eponymous star cluster.

Schematic representation of the Pleiades’ mechanism of action

The pleiades gene cluster in the Ustilago maydis (corn smut) genome encodes a family of proteins, the Pleiades, that target maize immunity. The two Pleiades Taygeta1 (Tay1) and Merope1 (Mer1) inhibit Reactive Oxygen Species (ROS) production, albeit in different cell compartments. Additionally, Mer1 acts in the nucleus to modify the activity of RFI2 homologues (Red and Far-Red Insensitive 2), a family of enzymes involved in early immune responses and that govern flowering time in plants.
