Much has been reported on the potential of roots to improve crop yield and resilience under drought. However, most studies on roots have used time consuming methods to assess rooting differences, limiting their use in breeding and providing “static” data about roots. The Lysimetric system (LysiField) simply consists of assessing plant water uptake to support … Continue reading Water Uptake – Little at Key Time is Beautiful
The University of Göttingen is an internationally renowned research university. Found in 1737 in the age of Enlightenment, the University is committed to the values of social responsibility of science, democracy, tolerance, and justice. Biogeochemistry of Agroecosystems team from the University of Göttingen (Jun.-Prof. Dr. Michaela Dippold) is expertise in isotopic studies related to roots … Continue reading University of Gottingen, Gottingen, Germany.
The University of Bayreuth is a public research university situated in Bayreuth, Germany. It was found in 1975 as a campus university focusing on international collaboration and interdisciplinarity. The geoscience team from Bayreuth University (Prof. Dr. Andrea Carminati and Mutez Ali Ahmed) is expertise in root and rhizosphere traits (mucilage and root hairs) related to water uptake. The team … Continue reading University of Bayreuth, Bayreuth, Germany.
This project involves utilization of interdisciplinary expertise in soil physics, plant physiology and biological systems modeling to progress understanding of water movement through soil-plant-atmosphere continuum with emphasis on characterization of rhizosphere/root hydraulic processes and their impact on drought adaptation.
The word of the moment in modern breeding programmes is “high-throughput phenotyping”. We need to measure well, measure with precision, and measure fast, and measure in bulk. But measure what? The LeasyScan platform has been developed to answer essential research questions concerning plant adaptation to drought and turn answers into breeding solutions. LeasyScan is here … Continue reading Sense and Sensibility
Why is it important? Lysimetric approach- the innovation How it works Importance to crop improvement Uniqueness of the facility and relevance to other locations Re-constructing the drought puzzle The two different angles this research led to Further Why is it important? Phenotyping, or measuring key traits of crops such as drought-tolerance, is crucial … Continue reading Lysimetric Facility
Phenotyping After the given plant phenotype is reasonably understood and the potential economic value of the phenotype assessed in silico, ultimately, the tools enabling massive screening of such phenotype is inevitable to assist the breeding programs. To encounter the typical breeding population size and screen for the phenotype relevant for crop production improvement in target … Continue reading Phenotyping
Trait Dissection Within team activities, dissection of physiological traits lay the baseline on which all other activities are built. We focus on understanding the range of plant adaptive mechanisms underlying the crop water usage which can potentially contribute to plant production advantage in various drought stress environments. Regulated dry down Transpiration response to VPD … Continue reading Trait Dissection
The drier parts of the world are where development challenges are the greatest and market failure is most acute, and few if any of these are more urgent than the ‘Sahel’ region of Africa. Its unusual tolerance of low inputs, especially water, make the cereal crop sorghum essential to human populations in the Sahel, where episodic drought is a fact of life. Despite its importance, sorghum improvement has lagged that of maize, wheat and rice, largely if not entirely due to greater effort invested in the ‘Big Three’.
For us gems means GEMS, or G*E*M*S (genotype by environment by management by society) interactions, i.e. the fact that crop yields results from complex biophysical interactions while acceptance depends on farmer/consumer preferences. This complexity becomes an opportunity when it is cracked into components that can be analysed, understood, predicted, and then used to prioritise research investments to maximise return. This is what we do, and this is when GEMS become gems!

A crop performs in different ways in different sites, years and agronomic managements. These are called genotype-by-environment-by management(G*E*M) interactions, and they are a main challenge for breeders and agronomists. There is one more layer of interaction, even more complex: the society (S). Farmers and consumers have different desires, needs, expectations, and a cultivar that fits one may not fit the other (G*E*M*S interactions). The puzzle is complex and challenging but if its components are understood, specific interventions can be undertaken.For instance, breeding for a particular genotype (G, with particular physiological characteristics), for a particular environment (E, with a particular kind of drought pattern that requires a specific adaptive trait), in a particular management practice (M, for instance a sowing density, or a N fertilizer treatment), and targeted to particular farmer/consumer (S, for instance a genotype that produces a lot of rich stover for cattle ranchers) is the need of the hour.
