Advances have been made in the study of invasive plants regulating secondary metabolites in response to environmental changes.

In response to changing environments, plants have evolved strategies such as adaptive strategies (by changing genotypes), ecological strategies (through esoteric plasticity), and resource allocation strategies (by changing the allocation of defense and growth/reproduction resources).
these strategies enable plants to adapt to biological and abscessive stress within different geographical boundaries.
in response to biological and abscessive stresses that vary between origin and invasive places and in latitude gradients, invasive plants may be able to facilitate the success of their invasion by regulating the distribution of different secondary metabolites.
, it is not clear whether and how the chemical response of invasive plants to herbivores is associated with the chemical response to the non-living environment.
Doctoral zodiac from the Invasive Ecology Unit of Wuhan Botanical Garden, Chinese Academy of Sciences Under the guidance of researcher Ding Jianqing, the biological (insect feeding) and non-biological (climate, solar radiation) factors faced by invasive plant Triadica Sebifera were investigated and extracted at the latitudes of origin (China) and invasive (United States) Analysis, and the collection of leaf samples to analyze the plant secondary metabolism (tranin and flavonoids) in the origin and invasion of the latitude gradient pattern;
studies have shown that the concentration ofof the original U blades and the feeding pressure of insects (chewing, stinging) are higher than invasive.
the distribution of mononin and flavonoids decreased with latitude at the origin, while there was no latitude gradient change at the invasive location.
analysis of U secondary metabolite data from previously published homogeneity garden experiments shows that genetic differences can lead to differences in chemical concentrations between origin and invasion.
Field data further show that in China of origin, the latitude pattern of Wu secondary metabolites is mainly a ideoplastic response to biological factors, while in the invasive United States, the latitude changes of secondary metabolites are mainly a ideoplastic response to the non-biological environment.
the study revealed that invasive plants can regulate the distribution of secondary metabolites, reduce chemicals used to protect against biological stress, and increase chemicals used to protect against abate stress, thereby facilitating their successful invasion.
findings have deepened understandings of how invasive plants weigh different secondary chemical reactions to adapt to heterogeneic environments on large bio-geographic scales.
the results of the study, published in Science of The Total Environment, with the first author of the study, were published on The Total Environment by Chemical responses of an invasive plant to herbivory and abiotic environments.
