Benzoxazinoid‐mediated microbiome feedbacks enhance Arabidopsis growth and defence

New Phytologist, EarlyView.
Summary Plants modulate their surrounding microbiome via root exudates and such conditioned soil microbiomes feed back on the performance of the next generation of plants. How plants perceive altered soil microbiomes and modulate their performance in response to such microbiome feedbacks, however, remains largely unknown.

Mass Spectrometry Imaging Combined With Single‐Cell Transcriptional Profiling Reveals the Multidimensional Spatial Distributions and Biosynthetic Pathways of Medicinal Components in Andrographis paniculata

Plant Biotechnology Journal, EarlyView.
ABSTRACT The synthesis and accumulation of active ingredients in medicinal plants are distributed in specific organs, tissues, and cell types, which are important for the exploitation of medicinal plants. However, the fine distribution of active ingredients is difficult to know. Here, the system of mass spectrometry imaging (MSI) integrated with single‐

Chromosome‐Level Genome Assembly of the Allotetraploid Gynostemma pentaphyllum Provides Novel Insights Into the Biosynthesis of Ginsenoside and Gypenoside LVI

Plant Biotechnology Journal, EarlyView.
ABSTRACT Gynostemma pentaphyllum, a herb used in tea and traditional Chinese medicine, shows geographic variation in its production of valuable dammarane‐type ginsenosides and gypenoside LVI between populations from Suining (SN) and Nanning (NN). To elucidate the mechanisms underlying this differential metabolite accumulation, a chromosome‐level genome

Distinct Defence Mechanisms of Allelopathic Rice Against Quinclorac‐Susceptible and ‐Resistant Barnyardgrass: Involvement of Specific Metabolites and Rhizosheath Microbiota

Plant Biotechnology Journal, EarlyView.
ABSTRACT Allelopathic rice is increasingly recognised as a promising strategy for sustainable weed management. Resistance to the herbicide quinclorac is widespread in barnyardgrass, but it remains unclear whether allelopathic rice exerts the same defence against herbicide‐susceptible and ‐resistant barnyardgrass. We conducted integrated transcriptomic,
