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.

Electrophilic carbonyl activation: competing condensative cyclizations of tryptamine derivatives [PDF]

, 2014
A series of tryptamine derived bisindole substrates were subjected to electrophilic activation of the func-tional grouping at their [alpha]-nitrogen in the form of iminium ions to enable cyclization onto the sterically hindered indole substructure.

Fungal Origins of the Bicyclo[2.2.2]diazaoctane Ring System of Prenylated Indole Alkaloids [PDF]

, 2012
Over eight different families of natural products, consisting of nearly seventy secondary metabolites, which contain the bicyclo[2.2.2]diazaoctane ring system, have been isolated from various Aspergillus, Penicillium, and Malbranchea species. Since 1968,

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‐

The Structure of Carboxyl Methyltransferase Provides Insights Into the Substrate Specificity and Divergent Evolution of Iridoid

Plant Biotechnology Journal, EarlyView.
ABSTRACT Iridoids constitute a prominent class of plant‐specialised metabolites, with carbocyclic iridoids (e.g., geniposide) and secoiridoids (e.g., loganin) diverging early in their biosynthetic pathways. This divergence is marked by substrate‐specific carboxyl methyltransferases—GjGAMT and CrLAMT—that catalyse the decisive methylation step in ...
