Case Studies

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 [...]

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 [...]

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 [...]

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 [...]

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 [...]

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. [...]
