Digital phenotyping in developing novel weed control

Weed control is becoming increasingly challenging because many herbicides become banned by authorities or weeds gain resistance against the active ingredients. Alternative methods frequently are labour- or energy- intensive. Exploring allelopathic substances might deliver novel weed control compounds. The duckweed growth inhibition test serves as an indicator whether a [...]

Analysing Seeds

Measuring the components of maize seeds On the surface of maize (Zea mays) seeds, areas of the embryo and the endosperm are visible, and fractions of these parts differ between maize cultivars. In yellow-seeded varieties, endosperm areas are darker-yellow, whereas the embryo areas are light-yellow [...]

Digital plant analysis serving in hazard assessment of future fuels

Fossil fuels have limited availability, and - most important - burning them endangers the world's climatic system. Thus, there is an urgent demand for alternate, environment-friendly fuel systems. A lot of energy can be captured using e.g. wind power stations but making this compatible to classical fuel uses is [...]

Plant Phenotyping: Past, Present, and Future

Phenotype analysis is challenging. It‘s even more challenging than genome analysis or other biological or chemical studies. Roland Pieruschka and Uli Schurr, phenotyping experts at Forschungszentrum Jülich back up this statement by considering the complex structure of plants, their fluctuating environments, and memory effects that translate through the plant lifecycles [...]

Using High-Throughput Phenotyping to Explore Growth Responses to Mycorrhizal Fungi and Zinc in Three Plant Species

Mycorrhizas generally are considered as beneficial plant-microbe interactions. Advanced non-invasive phenotyping technology gives insight in the dynamic development of the plants in response to mycorrhiza. Non-invasive assessments of the dynamic development of the digital biomass with a LemnaTec Scanalyzer revealed that mycorrhiza can cause growth depressions. The influence – positive [...]

LemnaTec colour analysis quantifies genotype-phenotype relations

Chloroplast development is a key function in plants and carotenoids carry out regulatory functions in the developmental program. Dissecting the underlying gene functions provides essential knowledge in understanding chloroplasts and thus photosynthesis. Mutants were analysed that correspond to genes with different functions in the regulatory network, and these mutants [...]

Water stress trials at Arkansas State University

Using an HTS Scanalyzer with RGB-, NIR-, and fluorescence cameras, researchers generated 4320 images of Arabidopsis plants in a drought study. Growth responses, water content, and chlorophyll-originating fluorescence signals were used to physiologically characterise the responses of the plants towards water limitation in different severities. Together with ionomic data, phenotypic data [...]

Automated growth stage determination with Rothamsted Field Scanalyzer

Current phenotyping technology fulfills tasks that are congruent with many “classical” measurements in agronomy or botany. Howerver, despite measuring the same object, data might lack comparability. One challenge is matching growth stages with non-invasive phenotyping data. Scientists at Rothamsted Research used machine learning methods to derive growth stage information in wheat [...]

Shanghai Jiao Tong University tested responses to root zone water availability

Researchers of the Shanghai Jiao Tong University used a LemnaTec Greenhouse Scanalyzer to assess the impact of root zone water availability on shoot growth performance of pakchoi (Brassica rapa chinensis) plants. Aim was to establish a method to discriminate root zone water availability levels by applying shoot phenotyping methods. Visible light [...]

Duckweed tests deliver data in screening for herbicidal compounds from natural sources

Looking for compounds with herbicidal activity, a fungus (Curvularia intermedia) was isolated from Pandanus amaryllifolius leaves, where it caused wilting symptoms. After isolating fungal metabolites, curvulatin and derivatives, toxicity was proven using a Lemna growth inhibiton test. LemnaTec software enabled growth analysis to figure out effective concentrations of the compounds. Future [...]

Review on Importance of Phenotyping in Breeding

Researchers from the Italian Research Centre for Vegetable and Ornamental Crops published a review that points out the high importance of phenotyping at various scales for improving future breeding procedures. In particular, when using material from gene banks for horticultural crop breeding, precise phenotypic information is essential. Nunzio D’Agostino [...]

Analysis of stress responsive pathways

When coping with environmental signals, complex networks of signal transduction and regulation processes are triggered. This particularly includes organelle functions. Nuclear-encoded organelle-targeted genes have central functions in such regulations. Mutations in such genes take influence on phenotypes and act pleiotropically. Researchers at the University of Nebraska Lincoln used a [...]

European infrastructures for sustainable agriculture

Nature Plants published a paper on research infrastructures authored by Jacques Roy, François Tardieu, Michèle Tixier-Boichard and Ulrich Schurr, pointing out the importance of phenotyping for the development of agricultural innovations that meet future demand of food and bio-based materials. Roy, Jacques; Tardieu, François; Tixier-Boichard, Michèle; Schurr, Ulrich (2017): European infrastructures [...]

Barley biomass accumulation

Barley biomass accumulation Researchers at the IPK Gatersleben analysed biomass accumulation in barley using a LemnaTec Greenhouse Scanalyzer. Phenotypic data delivered information on temporal patterns and genetic architecture underlying the biomass accumulation. Neumann, Kerstin; Zhao, Yusheng; Chu, Jianting; Keilwagen, Jens; Reif, Jochen C.; Kilian, Benjamin; Graner, Andreas (2017): Genetic architecture [...]

Bioactive compounds from rare endemic plant species

Conserving and protecting natural environments is highly valuable anyway. However, it promotes access to new sources of useful materials, too. An example from the Brazilian Cerrado shows that bioactive compounds with potential use as herbicides and insecticides can be derived from endemic species like Vellozia gigantea. Researchers from Brazil [...]

Phenomics at the Arkansas Center for Plant Powered Production

Manual phenotyping of large sets of plants requires a great deal of resources and expertise and is typically not feasible for detection of subtle phenotypes. Therefore, there is a growing need to develop quantitative, reproducible, and highly automated phenotyping systems to analyze large numbers of plants. [...]

Deep field phenotyping becomes reality at Rothamsted Research

In partnership with LemnaTec, the global plant phenotyping specialist, scientists at Rothamsted Research have implemented a Field Scanalyzer capable of continuously monitoring the development of crops under field conditions. The facility will be used initially to understand the development of numerous pre-breeding wheat lines that have been generated through the Wheat Genetic Improvement Network [...]
