Karban, R. et al.

2016

Read source ↗ All evidence

Summary

This review, attributed to Karban and colleagues and published in Annual Review of Plant Biology in 2016, synthesises the scientific literature on plant defence responses with a focus on secondary metabolite production. It likely covers both constitutive and inducible defence strategies, the ecological drivers shaping these traits, and the molecular signalling cascades involved. The paper is a key reference for understanding how plants allocate resources to chemical defence under biotic and abiotic pressures.

UK applicability

While the review is global in scope, its findings are directly applicable to UK agriculture and horticulture, particularly in the context of reducing pesticide dependency and understanding how crop management practices influence phytochemical profiles and natural pest resistance.

Key measures

Secondary metabolite classes (e.g. glucosinolates, phenolics, alkaloids, terpenes); defence signalling pathways (e.g. jasmonic acid, salicylic acid); inducible vs constitutive defence responses

Outcomes reported

The paper likely reviews the mechanisms by which plants produce secondary metabolites as defensive responses to herbivory, pathogens, and environmental stressors. It probably synthesises evidence on the signalling pathways, ecological functions, and agronomic relevance of these compounds.
