Previous studies have shown that climatic and anthropogenic factors influence the variations in stable isotope signature of tree materials an urban ecosystem. However, responses trees to various precipitation interventions are unclear. To fill research gap, isotopic composition (δ15N δ18O) total nitrogen content soil-plant system forests were measured, focusing on typical species (Populus tomen...

Ustiloxins are cyclopeptide mycotoxins produced by the pathogenic fungus Villosiclava virens of rice false smut. Ustiloxins A and B as two main mycotoxins were determined conveniently by LC-ESI-MS in the water extract from rice false smut balls which were mostly composed of the chlamydospores and mycelia of the pathogen. Both ustiloxins A and B in the water extract were also quantitatively anal...
