Abstract

Allelopathy can provide sustainable alternatives to herbicides because it is based on specific signals rather than generic toxicity. We show that the allelopathic activity of Spearmint and Watermint is linked with their main compounds, (-)-carvone and (+)-menthofuran, both deriving from (-)-limonene. Germination of Poppy and Cress, and root growth of are inhibited by very low concentrations of (-)-carvone, acting even through the gas phase. (+)-Menthofuran is active as well, but at lower efficacy. Using fluorescently tagged marker lines in tobacco BY-2 cells and roots, we demonstrate a rapid degradation of microtubules and a remodeling of actin filaments in response to (-)-carvone and, to a milder extent, to (+)-menthofuran. This cytoskeletal response is followed by cell death. By means of a Root Chip system, we can follow the tissue dependent response of the cytoskeleton and show a cell-type dependent gradient of sensitivity between meristem and distal elongation zone, accompanied by programmed cell death.

摘要

化感作用可以为除草剂提供可持续的替代方案，因为它基于特定信号而非一般毒性。我们发现留兰香和水薄荷的化感活性与其主要化合物（-）-香芹酮和（+）-薄荷呋喃有关，这两种化合物均由（-）-柠檬烯衍生而来。极低浓度的（-）-香芹酮甚至通过气相作用，就能抑制罂粟和水芹的萌发以及拟南芥的根生长。（+）-薄荷呋喃也有活性，但效果较弱。利用烟草BY-2细胞和拟南芥根中的荧光标记标记系，我们证明了微管的快速降解以及肌动蛋白丝的重塑，以响应（-）-香芹酮，并在较轻程度上响应（+）-薄荷呋喃。这种细胞骨架反应随后会导致细胞死亡。通过根芯片系统，我们可以跟踪细胞骨架的组织依赖性反应，并显示分生组织和远端伸长区之间细胞类型依赖性的敏感性梯度，同时伴有程序性细胞死亡。
