Status and prospects of allelopathy in molecular level and soil ecosystem

Allelopathy is one of the hottest research domains in ecology.In this paper,current advances of studies on allelopathy from molecular level to soil ecosystem level were reviewed.Effects of environmental stresses on allelopathy and impacts of allelopathy on plant cells and tissues were discussed.Recent progresses of the studies at molecular level were summarized in regard to locating gene controlling allelopathic effects,influencing protein and nucleic acid formation,gene expression and regulation,physiological and biochemical mechanism.Three aspects of the allelopathic effect on soil ecosystem perspective were also reviewed,which included soil quality,soil microorganism and soil fauna.Some problems and the further development on allelopathic research were put forward as well.
