The isohydric strategy of Platanus × hispanica tree shapes its response to drought in an urban environment.

Urban vegetation provides many ecosystem services like heat island mitigation. However, urban trees are subjected to the stresses that they are meant to alleviate, with drought being a main constraint. We investigated the drought response strategy of plane trees (Platanus × hispanica), focusing on stomatal regulation and metabolic remodelling.

Triticain alpha represents the major active papain-like cysteine protease in naturally senescing and ozone-treated leaves of wheat.

Current background tropospheric ozone (O) concentrations have significant adverse effects on wheat. O generally induces oxidative damages and premature leaf senescence leading to important yield losses. As leaf protein degradation and recycling is involved in both maintaining cell longevity during abiotic stresses and performing efficient nitrogen remobilization during senescence, we aimed to identify proteases involved in acidic endoproteolytic activities during natural and O-induced leaf senescence in wheat.

Evaluation of trace metal accumulation in six vegetable crops intercropped with phytostabilizing plant species, in a French urban wasteland.

The extensive development of agriculture in urban and peri-urban wastelands polluted with several trace elements (TE) poses risks to human health through contaminated food products. The objective was to explore the accumulation of TE in the various parts of vegetable crop plants (tomato, French bean, radish, potato, spinach, and leek) intercropped with phytostabilizing plant species (ryegrass and white clover, respectively). Field studies were conducted in a multicontaminated French urban wasteland with Cd, Cu, Pb and Zn, and an alkaline soil pH.

Combined Effects of Ozone and Drought on the Physiology and Membrane Lipids of Two Cowpea (Vigna unguiculata (L.) Walp) Cultivars.

The interactive effects of drought and ozone on the physiology and leaf membrane lipid content, composition and metabolism of cowpea (Vigna unguiculata (L.) Walp.) were investigated in two cultivars (EPACE-1 and IT83-D) grown under controlled conditions.
