Understanding the phytochemical diversity of plants: Quantification, variation and ecological function

This paper examines phytochemical diversity (chemodiversity) in plants, discussing its ecological relevance, reviewing methodological practices, and outlining future research directions.

Exogenous stimulation of Tanacetum vulgare roots with pipecolic acid leads to tissue-specific responses in terpenoid composition

This study examines how pipecolic acid treatment affects terpenoid composition in different tissues of tansy plants, revealing tissue-specific responses and metabolic differentiation.

Microbe-induced plant resistance against insect pests depends on timing of inoculation, but is consistent across climatic conditions

This study shows that beneficial soil bacteria enhance barley resistance to aphids, but the timing of inoculation matters, and this effect is consistent across different climate conditions.

Geographic distribution of terpenoid chemotypes in Tanacetum vulgare mediates tansy aphid occurrence and abundance

This study examines how geographic variation in tansy's terpenoid chemotypes influences aphid and ant communities across Germany.

Intraspecific chemical variation of Tanacetum vulgare at plant and plot level affects plant growth and reproductive traits in field plant communities

This study examines how intraspecific chemical variation in Tanacetum vulgare affects plant growth and reproductive traits in field communities, finding chemotype-specific effects and plot-level trait responses.

Chemodiversity affects preference for Tanacetum vulgare chemotypes in two aphid species

The paper tests how chemodiversity in Tanacetum vulgare affects aphid preference, finding that chemotype composition and diversity influence attractiveness differently in two aphid species.

Part-night exposure to artificial light at night has more detrimental effects on aphid colonies than fully lit nights

The paper examines how different levels of artificial light at night affect plant growth and aphid colonies, finding that partial light exposure has more severe negative impacts on aphids than full light exposure.

Persistence of plant-mediated microbial soil legacy effects in soil and inside roots

This study shows that microbial legacies from previous plants persist in soil and roots, influencing plant growth even after new plants colonize the soil.
