Effects of phosphorus stress on the growth and secondary metabolism of Artemisia argyi.

Phosphorus is essential in critical plant processes such as signaling, photosynthesis, energy metabolism, and enzyme activity during respiration. Phosphorus stress therefore has a significant impact on plant growth and metabolism. Here, we characterized the biochemical responses of Artemisia argyi Level.

Weed Suppression and Molecular Mechanisms of Isochlorogenic Acid A Isolated from Extract via an Activity-Guided Method.

Allelopathy is considered an environmentally friendly and resource-conserving approach to weed control because allelochemicals degrade easily and cause less pollution than traditional chemical herbicides. In this study, the allelopathic active constituents of were elucidated by activity-guided isolation and ultraperformance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS). First, a crude extract prepared in water was fractionated using macroporous resin D101 to obtain three fractions (Fr.

Caffeic Acid, an Allelochemical in , Inhibits Weed Growth via Suppression of Mitogen-Activated Protein Kinase Signaling Pathway and the Biosynthesis of Gibberellin and Phytoalexin.

is widely distributed in Asia, and it often becomes the dominant population in the field because of its strong ecological niche competitiveness. Allelochemicals secreted by plants are generally considered an important reason for their dominance in ecological competition. In this study, the allelochemicals in were screened by a series of experiments and their mechanisms were explored via transcriptomics.
