The ability of plants to fulfill nutritional needs by parasitizing neighboring plants has originated several times in angiosperm evolution. Molecular tools are now being exploited to investigate the evolutionary origins of plant parasitism and to dissect the genetic mechanisms governing parasitic plant-host plant interactions. Investigating the nature of signal exchanges between parasitic plants and their hosts serves as a tractable system for understanding how plants in general communicate in the environment. This work should also lead to the development of novel strategies for minimizing the devastation caused by parasitic weeds in international agriculture.
植物通过寄生邻近植物来满足营养需求的能力在被子植物进化过程中已经多次出现。分子工具目前正被用于研究植物寄生的进化起源，并剖析控制寄生植物与寄主植物相互作用的遗传机制。研究寄生植物与其寄主之间信号交换的本质，为理解植物在一般环境中如何进行交流提供了一个易于处理的系统。这项工作还应能促成新策略的开发，以尽量减少寄生杂草对国际农业造成的破坏。
