“…In support of this hypothesis, leaves of P. yunnanensis grown under conditions of excess Cd 2+ had a higher resistance to both phytophages (Spodoptera exigua and Botyodes diniasalis) and the pathogenic fungus Pestalotiopsis microspora, while they did not differ from the control ones in the concentration of secondary metabolites [291,292]. It is also interesting that the degree of cadmium protection of poplar from both phytophages and leaf pathogens (Pestalotiopsis microspora) depends on other elements of mineral nutrition: for example, when exogenous nitrogen was applied, the plant accumulated more Cd in leaves, which were, thus, less eaten by insect larvae or affected by fungus [293].…”

Poplar (Populus) is a genus of woody plants of great economic value. Due to the growing economic importance of poplar, there is a need to ensure its stable growth by increasing its resistance to pathogens. Genetic engineering can create organisms with improved traits faster than traditional methods, and with the development of CRISPR/Cas-based genome editing systems, scientists have a new highly effective tool for creating valuable genotypes. In this review, we summarize the latest research data on poplar diseases, the biology of their pathogens and how these plants resist pathogens. In the final section, we propose to plant male or mixed poplar populations; consider the genes of the MLO group, transcription factors of the WRKY and MYB families and defensive proteins BbChit1, LJAMP2, MsrA2 and PtDef as the most promising targets for genetic engineering; and also pay attention to the possibility of microbiome engineering.

“…27 In consistent with the elemental defense hypothesis, the larvae of Botyodes diniasalis, Clostera anachoreta, Sylepta derogate, and Spodoptera litura consumed fewer poplar leaves collected from Cd-treated trees. 28 The infestation of Alternaria brassicicola in Brassica juncea treated with CdCl 2 was inhibited, 6 and Pieris napi, Athalia rosae, and Phaedon cochleariae consumed less when fed with leaf disks of Arabidopsis halleri grown on Cd-amended soil. 29 So, the highly accumulated Cd in leaves is probably a strategy employed by the cotton plant to prevent cotton bollworm infestation (Table 2).…”

“…Exposure of plants to Cd significantly induces the emission of VOCs, effectively deterring females of both specialist and generalist herbivore species from oviposition [ 117 ]. Meanwhile, the application of exogenous spermidine and nitrogen demonstrates a positive correlation between plant growth and the inhibition of Cd on herbivore growth [ 118 , 119 ]. Herbivores consuming leaves with higher Cd content show inhibited growth [ 116 ].…”

Plants, as sessile organisms, uptake nutrients from the soil. Throughout their whole life cycle, they confront various external biotic and abiotic threats, encompassing harmful element toxicity, pathogen infection, and herbivore attack, posing risks to plant growth and production. Plants have evolved multifaceted mechanisms to cope with exogenous stress. The element defense hypothesis (EDH) theory elucidates that plants employ elements within their tissues to withstand various natural enemies. Notably, essential and non-essential trace metals and metalloids have been identified as active participants in plant defense mechanisms, especially in nanoparticle form. In this review, we compiled and synthetized recent advancements and robust evidence regarding the involvement of trace metals and metalloids in plant element defense against external stresses that include biotic stressors (such as drought, salinity, and heavy metal toxicity) and abiotic environmental stressors (such as pathogen invasion and herbivore attack). We discuss the mechanisms underlying the metals and metalloids involved in plant defense enhancement from physiological, biochemical, and molecular perspectives. By consolidating this information, this review enhances our understanding of how metals and metalloids contribute to plant element defense. Drawing on the current advances in plant elemental defense, we propose an application prospect of metals and metalloids in agricultural products to solve current issues, including soil pollution and production, for the sustainable development of agriculture. Although the studies focused on plant elemental defense have advanced, the precise mechanism under the plant defense response still needs further investigation.
