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 [...]

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 [...]

LemnaTec LabScanalyzer supports breeding for climate-resilient beans.

Beans are a key protein source for large parts of the world population, but bean plant cultivation is threatened by adverse climatic conditions. Breeding aims at improving future bean varieties for better yield performance under environmental stress. Researchers at the Mexican Colegio de Postgraduados Institute applied a LemnaTec LabScanalyzer [...]

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 [...]

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 [...]

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 [...]

The advantage of digital phenotyping in environmental stress assessment

The advantage of digital phenotyping in environmental stress assessment Abiotic stresses have large potential of damaging plants, and this is one of the major threats in crop production. Detecting and quantifying stress effects gives a strong advantage in rating plant performance and stress tolerance. Digital [...]

Phenotyping for improved biomass

When growing plants for bio-energy, it is highly desirable to avoid any competition with food production and to minimise any energy-demanding agricultural management such as fertilisation. Thus, ideally such plants grow on marginal land without adding fertiliser and without irrigation. The discrepancy between low resource availability and maximised biomass production [...]

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 [...]

Desert tomato plants grow at minimal water availability

Wild relatives of crops frequently are more resistant to environmental stress factors than modern crop cultivars. Therefore, wild relatives might be sources of genes that improve stress tolerance or resistance. A wild tomato species Solanum pennellii originating from desert environments has thick leaves and copes well with water limitation. [...]

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 [...]

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 [...]

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 [...]

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 [...]

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 [...]
