A multi-omics approach to unravel the interaction between heat and drought stress in the holobiont.

The impact of combined heat and drought stress was investigated in and compared to individual stresses to reveal additive effects and interactions. A combination of plant metabolomics and root and rhizosphere bacterial metabarcoding were used to unravel effects at the plant holobiont level. Hierarchical cluster analysis of metabolomics signatures pointed out two main clusters, one including heat and combined heat and drought, and the second cluster that included the control and drought treatments.

L. shares a typical secondary chemistry with other species (fam. ), characterized by the tendency to intensively produce monoterpenoid iridoids, whereas the phenylpropanoid chemistry is steered towards the production of a caffeic acid ester, rosmarinic acid.

Introduction: Nitrogen (N) and iron (Fe) are involved in several biochemical processes in living organisms, and their limited bioavailability is a strong constraint for plant growth and yield. This work investigated the interplay between Fe and N nutritional pathways in tomato plants kept under N and Fe deficiency and then resupplied with Fe and N (as nitrate, ammonium, or urea) through a physiological, metabolomics and gene expression study.
Results: After 24 hours of Fe resupply, the Fe concentration in Fe-deficient roots was dependent on the applied N form (following the pattern: nitrate > urea > ammonium > Fe-deficient control), and whereas in leaves of urea treated plants the Fe concentration was lower in comparison to the other N forms.

Article Synopsis
- Phenoxy radical coupling reactions are essential in nature for creating complex molecules like lignin and hold promise for lab synthesis of valuable polyphenol compounds.
- Previous studies indicated that different compounds, such as stilbenes and phenylpropanoids, yield varying dimerization and coupling products when using certain enzymes.
- This research identifies important structural features that enhance these reactions, particularly the presence of an exocyclic double bond, and establishes a controlled method for producing specific phenolic dimers and tetramers.
