许多动物识别亲属的能力使它们能够进化出各种各样的合作行为;植物的这种能力研究得较少。许多植物，包括三齿蒿，被发现对实验受伤的邻居发出的挥发性信号做出反应，以提高对草食动物的抵抗力。我们报告说，这种沟通是更有效的A。tridentata植物更密切相关的微卫星标记的基础上。在现场的植物，从实验修剪近亲收到线索经历了更少的叶草食动物在生长季节比那些收到线索从修剪邻居更远亲。这些结果表明，植物对来自亲属的提示做出不同的反应，使得发射者不太可能帮助陌生人，而接收者更有可能对来自亲属的提示做出反应。更有效的防御增加了越来越多的有利后果的清单亲属识别植物。
The ability of many animals to recognize kin has allowed them to evolve diverse cooperative behaviours; such ability is less well studied for plants. Many plants, including Artemisia tridentata, have been found to respond to volatile cues emitted by experimentally wounded neighbours to increase levels of resistance to herbivory. We report that this communication was more effective among A. tridentata plants that were more closely related based on microsatellite markers. Plants in the field that received cues from experimentally clipped close relatives experienced less leaf herbivory over the growing season than those that received cues from clipped neighbours that were more distantly related. These results indicate that plants can respond differently to cues from kin, making it less likely that emitters will aid strangers and making it more likely that receivers will respond to cues from relatives. More effective defence adds to a growing list of favourable consequences of kin recognition for plants.
