ABSTRACT
The plant hormone strigolactones (SLs) play crucial roles in regulating development and adaptations to abiotic stresses. Even though the functional of SLs have been identified response stresses, function, mechanism are not fully established under alkaline stress. In this study, we that exogenous SL could improve tolerance soybean seedlings, especially when treated with 0.5 μM SL. application remarkably reduced malondialdehyde content, hydrogen peroxide increased activity antioxidant enzymes stress, suggesting improved by defense capacity. RNA sequencing data showed 530 special differentially expressed genes treatment mainly were associated processes phenylpropanoid biosynthetic pathway. Some transcription factors also induced stress as confirmed quantitative real-time PCR (qRT-PCR). Furthermore, largely Na content leaves decreased roots which suggested might promote transport from seedlings. Meanwhile, other elements such K, Mg, Fe, Cu or Collectively, our results a role capacity, specific gene expression, alterations ionic contents alleviate harmful effects
