*Here, we analysed the role of direct and indirect plant interactions in the invasion process of Acer negundo along a natural successional gradient in the Middle Rhone floodplain (France). Saccone, Patrick PagÃ¨s, Jean-Philippe Girel, Jacky Brun, Jean-Jacques Michalet, Richard negundo airborne pollen that can influence the reproductive processes as well as respiratory pollen allergies in the future.Īcer negundo invasion along a successional gradient: early direct facilitation by native pioneers and late indirect facilitation by conspecifics. Our results indicate that increase in atmospheric CO2 concentrations can have a negative influence of some features of A. No changes were detected in the SDS-PAGE protein profiles and in sucrose and glucose levels. negundo pollen exposed to increasing levels of the pollutant. The patient sera revealed increased IgE reactivity to proteins of A. Carbon dioxide exposure affected negatively pollen fertility, total soluble protein content, and fructose content. Also, pollen fructose, sucrose, and glucose values were determined. Pollen fertility was determined using viability and germination assays, total soluble protein was determined with Coomassie Protein Assay Reagent, and the antigenic and allergenic properties were investigated by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and immunological techniques using patients' sera. Pollen was collected directly from the anthers and in vitro exposed to three CO2 levels (500, 1000, and 3000 ppm) for 6 and 24 h in an environmental chamber. In this work, it was investigated the effects of carbon dioxide (CO2) on Acer negundo pollen fertility, protein content, allergenic properties, and carbohydrates.

Horses should be prevented from grazing samaras from Acer spp. If pastured horses present with clinical and biochemical signs of severe muscle damage then the environment should be checked for the presence of these trees. Sycamore and box elder trees in New Zealand are a source of hypoglycin A associated with the development of atypical myopathy. Cases of atypical myopathy were diagnosed on properties where samaras containing hypoglycin A were also found. Hypoglycin A was detected in 10/15 samples of samaras from sycamore maple and box elder from throughout New Zealand. Hypoglycin A was detected in the serum of those horses but not in the healthy controls. Serum samples from the four cases and four unaffected horses were analysed for the presence of hypoglycin A, profiles of acylcarnitines (the definitive diagnosis for atypical myopathy) and activities of creatine kinase and aspartate aminotransferase.Markedly elevated serum activities of creatine kinase and aspartate aminotransferase, and increased concentrations of selected acylcarnitines were found in the case horses. in New Zealand, samples were collected from trees throughout the country that were associated with historical and/or current cases of atypical myopathy, and analysed for hypoglycin A. To determine if hypoglycin A is present in the samaras of Acer spp. may contain hypoglycin A, that has been associated with cases of atypical myopathy in Europe and North America. negundo) were present in the area where the horse had been grazing.
