Sentinel-2 MSI - Level 2A (MAJA Tiles) - Germany

This collection contains Sentinel-2 Level 2A surface reflectances, which are computed for the country of Germany using the time-series based MAJA processor. During the Level 2A processing, the data are corrected for atmospheric effects and clouds and their shadows are detected. The MAJA L2A product is available online for the last 12 months. Further data are kept in the archive and are available upon request. Please see https://logiciels.cnes.fr/en/content/maja for additional information on the MAJA product. The MAJA product offers an alternative to the official ESA L2A product and has been processed with consideration of the characteristics of the Sentinel-2 mission (fast collection of time series, constant sensor perspective, and global coverage). Assumptions about the temporal constancy of the ground cover are taken into account for a robust detection of clouds and a more flexible determination of aerosol properties. As a result, an improved determination of the reflectance of sunlight at the earth's surface (pixel values of the multispectral image) is derived. Further Sentinel-2 Level 2A data computed using MAJA are available on the following website: https://theia.cnes.fr

Sentinel-2 MSI - Level 3A (MAJA/WASP Tiles) - Germany

This collection contains synthesized Sentinel-2 Level 3A surface reflectances for Germany on a monthly basis computed by the WASP processor (which utilizes L2A products derived from the MAJA processor). During the Level 3A processing, atmospherically corrected data from a predefined time interval are collected, weighted based on temporal distance and integrated to a new data set with the aim of removing clouds. Thereby, monthly Sentinel-2 Level 3A composites are provided for whole Germany. Please see https://logiciels.cnes.fr/en/content/maja for additional information on the MAJA product. Further Sentinel-2 Level 3A data computed using MAJA are available on the following website: https://theia.cnes.fr

Documentation of IFAT 2016 Side Event Climate-friendly Waste Management through NAMAs in Emerging Economies and Developing Countries

Nationally Appropriate ⁠Mitigation⁠ Actions (NAMA) allow emerging economies and developing countries to design waste management strategies and systems that lead to effective greenhouse gas (GHG) reductions. On a side event at IFAT / Munich in June 2016 international experts from climate policy and waste management exchanged their experiences on key features of Waste-NAMAs, such as funding and financing, participatory processes and informed decision-making across all levels and involvement the private sector.  The example of monitoring, reporting and verification (MRV) of Peruvian Waste-NAMA demonstrated the workload involved and the demands for standardized methods.

Function of BAK1 in plant immunity

Das Projekt "Function of BAK1 in plant immunity" wird/wurde gefördert durch: Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung. Es wird/wurde ausgeführt durch: Universität Basel, Botanisches Institut, Abteilung Pflanzenökologie.In nature most plants are resistant to most pathogens and disease is rather the exception than the rule. A key aspect of this phenomenon is a resistance response called 'innate immunity'. It is based on the host recognition of characteristic microbial molecules, known as MAMPs (Microbe Associated Molecular Patterns), by specific receptors called pattern recognition receptors (PRRs). A paradigm of a MAMP is flagellin, the main building unit of the mobility organ of bacteria. Bacterial flagellin is perceived by the pattern recognition receptor FLS2 (FLagellin Sensing 2) at the surface of plant cells. Binding of flagellin to FLS2 on the outside of the cells induces a set of physiological responses inside the cells, which we can easily measure in our lab and which ultimately contribute to limitation of bacterial invasion and plant resistance. Our lab has focused in the last years in understanding how FLS2, a single pass transmembrane molecule, functions to transmit the signal from outside of the cell to its inside. We could demonstrate that upon stimulation with flagellin, FLS2 associates very quickly at the plasma membrane with a second receptor known as BAK1 (BRI1-Associated Kinase 1). This was initially a big surprise because BAK1 was already known as the co-receptor of the BRI1, a plant hormone receptor which regulates plant development but not plant immunity. More recently we developed an original biochemical approach to label and detect phosphorylated receptors in cell cultures in vivo. This allowed us to show that the transmission of the flagellin signal occurs via phosphorylation of FLS2 and BAK1 within seconds after flagellin perception. In addition we could show that BAK1 is capable of regulating several PRRs other than FLS2 by forming stable complexes. Thus BAK1 appears to be a crucial regulator or plant immunity in addition to its role in plant development. Our recent progress on the plants' flagellin-sensing system was mostly obtained using Arabidopsis as plant model. In view of the ability of BAK1 to form stable complexes with PRRs in a ligand-dependent manner, we are now interested to fish out and identify new PRRs, notably from crop species, using a proteomic approach. The identification of more PRRs in different plants is a very important step toward understanding plant innate immunity. In more general terms, better knowledge about innate immunity is crucial because it may reveal new strategies to fight the devastating impact of some plant diseases.

Regulation of LRR-Receptor kinases in plant innate immunity

Das Projekt "Regulation of LRR-Receptor kinases in plant innate immunity" wird/wurde gefördert durch: Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung. Es wird/wurde ausgeführt durch: Universität Basel, Botanisches Institut, Abteilung Pflanzenökologie.In nature most plants are resistant to most pathogens. A key aspect of this phenomenon is host recognition of characteristic microbial molecules, known as PAMPs (Pathogen/ Microbial Associated Molecular Patterns), by specific receptors. Flagellin, the main building unit of the mobility organ of bacteria, is perceived by the receptor kinase FLS2 (FLagellin Sensing 2) at the surface of plant cells. Binding of flagellin to the domain of FLS2 exposed to the extracellular compartment induces a set of physiological responses inside the cells, which we can easily measure in our lab and which ultimately contribute to limitation of bacterial invasion and plant resistance. How does FLS2 function to transmit the signal from outside of the cell to its inside? Recently, we could demonstrate that upon stimulation with flagellin, FLS2 associates very quickly at the plasma membrane with a second receptor known as BAK1 (BRI1-Associated Kinase 1). Mutant plants lacking the BAK1 protein respond less to flagellin as well as to other PAMPs, indicating its role in positive regulation of PAMP detection. A big surprise is that BAK1 is already known as the co-receptor of the membrane BRI1. BRI1 is another receptor kinase which recognizes the phytohormone brassinosteroids involved in regulation of plant growth and development. The novel function of BAK1 in innate immunity is being further addressed in our lab with the current project using a combination of biochemistry, molecular biology and genetics. In particular we want to study detailed mechanisms of BAK1 and FLS2 for transducing the flagellin signal. Our studies have an essential role in understanding plant innate immunity in a broad sense, and we hope this will help to elucidate molecular mechanisms regulating plants receptor kinases not only in defense but also in development.
