A constitutively monomeric UVR8 photoreceptor confers enhanced UV-B photomorphogenesis

The plant ultraviolet-B (UV-B) photoreceptor UVR8 plays an important role in UV-B acclimation and survival. UV-B absorption by homodimeric UVR8 induces its monomerization and interaction with the E3 ubiquitin ligase COP1, leading ultimately to gene express ...

Contrasting Leaf Trait Responses of Conifer and Broadleaved Seedlings to Altered Resource Availability Are Linked to Resource Strategies

Christoph Bachofen, Yan Li Zhang

(1) Understanding tree seedling responses to water, nutrient, and light availability is crucial to precisely predict potential shifts in composition and structure of forest communities under future climatic conditions. (2) We exposed seedlings of widesprea ...

Effect of crop rotation on mycorrhizal colonization and wheat yield under different fertilizer treatments

Pierre Rémi Mariotte

Break crops are used in agriculture to reduce soil pathogens and improve yield of subsequent cereal crops. However, they can also affect soil microbial communities beneficial to plant growth including arbuscular mycorrhizal fungi (AMF). Two wheat genotypes ...

Metal accumulation and response of antioxidant enzymes in seedlings and adult sunflower mutants with improved metal removal traits on a metal-contaminated soil

Jean-Paul Schwitzguebel, Erika Nehnevajova

Sunflower mutant lines with an enhanced tolerance and metal accumulation capacity obtained by mutation breeding have been proposed for Zn, Cd and Cu removal from metal-contaminated soils in previous studies. However, soils contaminated with trace elements ...

Phytochrome interacting factors 4 and 5 control seedling growth in changing light conditions by directly controlling auxin signaling

Jacques Rougemont, Ioannis Xenarios, Christian Fankhauser

Plant growth is strongly influenced by the presence of neighbors that compete for light resources. In response to vegetational shading shade-intolerant plants such as Arabidopsis display a suite of developmental responses known as the shade-avoidance syndr ...

Spatially and genetically distinct control of seed germination by phytochromes A and B

Christian Fankhauser

Phytochromes phyB and phyA mediate a remarkable developmental switch whereby, early upon seed imbibition, canopy light prevents phyB-dependent germination, whereas, later on, it stimulates phyA-dependent germination. Using a seed coat bedding assay where t ...

Polyploidy and invasion success: trait trade-offs in native and introduced cytotypes of two Asteraceae species

Alexandre Buttler, François Gillet, Aurélie Thébault

Invasion success is favoured by the introduction of pre-adapted genotypes. In addition, novel pressures in the introduced range may lead to phenotypic changes related to fitness or competitive ability of introduced plants. Polyploidy appears to be over-rep ...

Increased tolerance of sunflower mutant seedlings to Cd and Zn in hydroponic culture

Jean-Paul Schwitzguebel, Erika Nehnevajova

Cadmium and zinc show similarities in their chemistry, geochemistry and environmental properties. Whereas Cd is a phytotoxic non-essential element, Zn is an essential trace element for plant growth and development. Zinc plays a fundamental role in several ...

Competitive effects of herbaceous vegetation on tree seedling emergence, growth and survival: does gap size matter?

Alexandre Buttler, Charlotte Vandenberghe, François Frelechoux

Question: What is the effect of gap size on the seedling emergence, growth and survival of four common tree species in wooded pastures? Location: A pasture in the Jura mountains, Switzerland. Methods: Seeds were sown in a complete three-way factorial desig ...

Lipoxygenase-mediated metabolism of storage lipids in germinating sunflower cotyledons and b-oxidation of (9Z,11E,13S)-13-hydroxy-octadeca-9,11-dienoic acid by the cotyledonary glyoxysomes

Institut fur Botanik, Universitat Munster, Schlossgarten 3, 48149, Munster, Germany. During the early stages of germination, a lipid-body lipoxygenase is expressed in the cotyledons of sunflowers (Helianthus annuus L.). In order to obtain evidence for the ...
