TLDR
The main environmental factors that can streamline or alter the production or concentration of secondary metabolites in plants are reviewed.
Abstract
Since secondary metabolites represent a chemical interface between plants and surrounding environment, their syntheses are frequently affected by environmental conditions. Thus, variations in the total content and/or of the relative proportions of secondary metabolites in plants can take place. We review the main environmental factors that can streamline or alter the production or concentration of secondary metabolites in plants. How seasonality, circadian rhythm, developmental stage and age, temperature, water availability, UV radiation, soil nutrients, altitude, atmospheric composition and tissue damage influence secondary metabolism are discussed.

Impact of various factors responsible for fluctuation in plant secondary metabolites

TL;DR: A detailed view of the possible roles of the various factors in secondary metabolite instability is presented to give probable explanations on why the content of secondary metabolites fluctuates in subsequent generations of pure lines as well as advanced generations (F7 onward) of intra- and inter-specific crosses.

Agroecosystem Management and Nutritional Quality of Plant Foods: The Case of Organic Fruits and Vegetables

TL;DR: A model developed to calculate the health outcome of increasing the intake of fruits and vegetables was used to tentatively estimate the potential increase in life expectancy that would be achieved by switching from conventional to organic produce without changing the amount consumed per day.

Exogenous influences on plant secondary metabolite levels

TL;DR: This contribution aims to review the most important mechanisms of various abiotic and biotic interactions, such as pathogenic microorganisms and herbivory, by which plants respond to exogenous influences, and will also report on time-scale variable influences on secondary metabolite profiles.
