SGER: Ecological Effects of Plant-Generated Organic Sulfide Emissions

某些植物通过根部渗出有机硫化物。在其纯净状态下，许多这些硫化物具有抑菌、杀真菌、杀线虫和杀虫的特性。目前尚不清楚植物释放的硫化物是否足以在自然系统中产生这些影响。侦探研究人员将调查这些化合物的系统发育分布，并确定它们的生产是否对植物群落有影响。如果植物确实将硫化物纳入其整体响应库，其影响可能是巨大的，对这一现象的理解可能会显著改变未来对群落和生态系统关系的调查。

Certain plants exude organic sulfides through their roots. In their pure state, many of these sulfides have bacteriostatic, fungicidal, nematicidal, and insecticidal properties. It is not known whether plants emit sufficient amounts of the sulfides to have these effects in natural systems. The P.I.'s will investigate the phylogenetic distribution of these compounds and determine whether their production has effects on the plant community. If plants do incorporate sulfides into their overall response repertoire, the effect could be substantial and an understanding of the phenomenon could significantly alter future investigations of community and ecosystem relationships.
