Monoterpene indole alkaloids encompass a diverse class of plant natural products. Many of these valuable compounds, including the anticancer medici...

Chromatin plays a central role in gene regulation, but chromatin systems are only known for a few model species. This study analyses chromatin regulatory landscapes in brown algal lineages to elucidat...

Chemical defenses are fundamental in organismal biology and widely used in medicine and agriculture. Plant defense chemistry evolves in response to...

Researchers at the Max Planck Institute for Chemical Ecology and the University of Kiel have provided experimental evidence showing that reducing plant species diversity alters plant chemical signals ...

Peng et al. identify a class of non-aromatic, chorismate-derived compounds, abundant in the roots of Arabidopsis thaliana. These compounds are made by a biosynthetic gene cluster comprising five adjac...

Paralogs, copies of a gene, form an important basis for novelty during evolution. Analysis of such gene duplications is important to understand the emergence of novel traits during evolution. DupyliCa...

Kang et al. show that coronatine hijacks the ABA hydroxylase CYP707A1 in A. thaliana to override stomatal defense. While CYP707A1 also enables rapid light-induced stomatal opening, C. rubella and E. s...

Microbe interaction not only plays an integral role in plant growth and adaptation, but also may lead to genetic integration. Horizontal gene transfer (HGT) from microbes occurs in all major plant groups and appears to be frequent in charophytes and bryophytes. Horizontally acquired microbial genes have contributed to major physiological and structural innovations in land plants. This paper discusses microbial interactions and genetic integration, with a particular focus on recent data regarding the role of horizontally acquired microbial genes in land plant evolution. We suggest that microbes are essential resources for plants, both as an ecological component and as a source of novel genetic material, and that plant colonization of land and further diversification represent a process of exploitation of microbial resources.

An iridoid glycoside, rhododeoside C (1), and a pyridine derivative, rhododeodine A (2), both previously undescribed, were isolated from the flowers of Rhododendron decorum. The structures were elu...

We investigated how maize root bacteria—alone or in community—tolerate and metabolize antimicrobial compounds of their host plant. We found that the capacity to metabolize such a compound impacts bact...

Proceedings of the National Academy of Sciences (PNAS), a peer reviewed journal of the National Academy of Sciences (NAS) - an authoritative source of high-impact, original research that broadly spans...

Plant performance depends on the soil microbiome. While microbiome feedbacks are well documented, the mechanisms by which plants perceive and mediate these feedbacks remain unclear. We established a f...

Identifying the metabolic and genetic changes that confer evolutionary novelty is essential for understanding the factors facilitating or constraining the occurrence of traits. We show that dimethyl d...

Phytohormone cross-talk balances growth and insect defense across growth stages.

This study reports that herbivory-induced volatiles can trigger plant–soil feedbacks that boost performance and yields of cereals in the field.

Vessel elements arise from cambium stem cells and support plant growth by supplying water and nutrients. This study reveals that strigolactone signalling inhibits vessel formation in response to droug...

Establishment of the apoplastic root barrier known as the Casparian strip occurs early in root development. In legumes, this area overlaps with nitrogen-fixing nodule formation, which raises the possi...

Plant roots are colonised by diverse microbial communities. These communities are shaped by root exudates including plant specialized metabolites. Benzoxazinoids are such secreted compounds of maize. ...

The liverwort Marchantia polymorpha has emerged as a model for studying plant immunity in bryophytes, providing unique insights into conserved defense mechanisms across land plants. By contrast, March...

Grenz et al. interrogate the Pseudomonas syringae species complex for its capacity to infect evolutionarily divergent host plants. Their results demonstrate that broad host isolates from phylogroup 2 rely on the lipopeptide toxin syringomycin to promote host necrosis and enhance bacterial growth in plants.

This study shows how changes in copy numbers in gene families are linked to plants' ability to survive extreme dehydration.
