A genetically conserved and transferable defense mechanism protects plants from herbivores

Ref.-No.: 1602-6322-LI

Processes and Methods (incl. Screening) : Life Sciences-HTS/HCS
Nucleic Acid-, Protein and Cell-related Technologies : Protein related
Green Biotech

Our scientists have identified a conserved defense mechanism covering a new metabolite in tobacco that protects against leafhoppers. They have discovered how to reconstitute it in vitro and engineer the compound in crop plants, demonstrating that it confers resistance to herbivores.

A method for the production of plants with altered photorespiration and improved CO2 fixation

Recently, many efforts have been made to improve growth and yield of crop plants. CO2 fixation in plants is primarily catalyzed by the enzyme ribulose-1,5-bisphosphate carboxylase (Rubisco). The inherent inefficiency of Rubisco necessitates an additional metabolic process termed photorespiration, which results in the loss of carbon and energy. In fact, it has been estimated that plants lose approximately 25% of the fixed carbon due to photorespiration. Despite several attempts to improve ...

A novel class of herbal compounds saiginols with strong UV-B absorbing properties

Ref.-No.: 0402-4816-MG

Green Biotech

UV-B radiation is a major damaging agent causing damage to plants, tissues and human or animal skin upon exposure. To persist strong UV-B radiation plants produce additional antioxidant sunscreen pigments that belong to the chemical compound family of phenylpropanoids. Since many conventional compounds with sunscreen protection potential do not enter the market due to toxic side effects or they bear the risk to become environmental pollutants when accumulating in natural resources, application ...

Carbon-neutral and carbon-positive photorespiration bypass routes supporting higher photosynthetic rate and yield

Ref.-Nr. 0402-5003-MG

Green Biotech

Carbon fixation is arguably the most important biochemical processes on earth, supporting our biosphere by transforming inorganic carbon into organic matter and literally feeding all life forms. The reductive pentose phosphate cycle (rPP, also known as the Calvin–Benson–Bassham Cycle) is responsible for ≥95% of the carbon fixed in the biosphere. Although under a strong selective pressure for eons, this process displays major inefficiencies, some are due to the low catalytic rate and the ...

Chlamydomonas algae strains for molecular farming

Ref.-No.: 0402-3923-MG

Green Biotech

The unicellular green alga Chlamydomonas reinhardtii is both an invaluable model organism for plant biology and an attractive biotechnological production system for biofuels and biopharmaceuticals. Despite the availability of efficient methods for introduction of foreign genes into the nuclear genome of the alga, transgene expression levels are usually very poor. This is a serious limitation that has severely hampered both post-genomics research in Chlamydomonas and use of the ...

Leaf metabolites as markers for mycorrhizal colonization of plant roots

Ref.-Nr.: 1602-5392-LI

Green Biotech

Screening the level of specific blumenols in plant leaves allows simple implementation in marker assisted breeding and high-throughput analysis.

Novel compounds against rust and smut fungi

Ref.-No.: 0706-6146/6147/6148-IKF

Green Biotech

Rust and smut fungi are plant pathogens which cause diseases of considerable relevance in agriculture. Both fungi are biotrophic and require living plant tissue for proliferation. Instead of killing their host plants, they manipulate host cells to assure that these sustain fungal growth. During the infection, the fungi release an entire cocktail of so-called effectors which function either in the interaction zone between fungus and host or are delivered to plant cells. Effector proteins suppress ...

Novel compounds for plant disease control

Nucleic Acid-, Protein and Cell-related Technologies : Protein related
Green Biotech

Plant pathogenic fungi, oomycetes and bacteria have highly diverse lifestyles, infection strategies and morphologies. Therefore, pesticides frequently target basic cellular processes, as these are well characterized and often very similar among plant pathogens. Many pesticides target enzymes that play a role in e.g. nucleic acid synthesis, respiration, cell division and other essential cellular processes. However, the molecular ...
