  摘要：Plant absorption is important for the entry of many pollutants into food chains. Although terrestrial microplastics (MPs) can be absorbed by the roots1,2, their upward translocation is slow1. Meanwhile, atmospheric MPs are widely present3,4, but strong evidence on their direct absorption by plants is still lacking. Here, analyses using mass spectrometry detection show the widespread occurrence of polyethylene terephthalate (PET) and polystyrene (PS) polymers and oligomers in plant leaves, and ...

  摘要：Flowering plant sexual reproduction requires double fertilization, yielding embryo and endosperm seed compartments: the latter supports embryo growth and seed germination. In an experiment to generate haploid embryos through inhibition of pollen phospholipase activity in sunflower (Helianthus annus), we serendipitously discovered that emasculated sunflowers spontaneously form parthenogenic haploid seed. Exploration of genetic, chemical and environmental factors demonstrated that a specific gen...

  摘要：Methane is an important greenhouse gas1 and its atmospheric concentration has almost tripled since pre-industrial times2, 3-4. Atmospheric methane mixing ratios vary seasonally, with the seasonal cycle amplitude (SCA) having decreased in northern high latitudes and increased in the subtropics and tropics since the 1980s5,6. These opposing SCA trends can help understanding of long-term changes in the global methane budget, as methane emissions and sinks have opposing effects on the SCA5. Howeve...
