To better understand the successful invasion mechanism, many hypotheses have been proposed. However, the roles of hormones in it are not clear, especially for the differential effects of hormones on invasive and native plants, and its mechanisms. In this study, we hypothesized that there was not only a difference in hormone (auxin) concentration between invasive and native plants but also a difference in the effect of auxin on invasive and native plants. The above characteristics drove the successful invasion of invasive plants. To verify this hypothesis and investigate the mechanism, auxin concentration, and physiological index determinationFrontiers in plant science1705498https://www.ebi.ac.uk/biostudies/studies/S-EPMC12695812biostudies-literatureThe mechanism of auxin driving <i>Xanthium strumarium</i> invasion.PMC12695812Feng YLZhao TTWu HLHan XQi FZZhang CDu YXCheng YfalseThe mechanism of auxin driving <i>Xanthium strumarium</i> invasion.Biological invasion is a critical ecological challenge, exerting profound impacts on ecosystem stability, public health, and economic sustainability.
