Advances in the investigation of triticeae crop allelopathy and molecular ecology

This article reviews recent advances in the investigation of triticeae crop allelopathy. The controversial research of wheat and barley allelopathic germplasm, resource screening and evaluation is discussed. The author also discusses genetic diversity of triticeae crops from molecular marker ISSR and allelochemical research. Finally, based on the development trend of research in plant allelopathy, the author highlights important issues deemed critical to the study of allelopathy of triticeae crops, including gene expression and signal regulation in molecular ecology and rhizospheric biological processes of wheat and barley allelopathy.
