AB  - Exogenous applications of silicon (Si) can initiate cellular defence pathways to enhance plant resistance to abiotic and biotic stresses. Plant Si accumulation is regulated by several transporters of silicic acid (e.g. Lsi1, Lsi2, and Lsi6), but the precise mechanisms involved in overall Si transport and its beneficial effects remains unclear. In stressed plants, the accumulation of Si leads to a defence mechanism involving the formation of amorphous or hydrated silicic acid caused by their polymerization and interaction with other organic substances. Silicon also regulates plant ionic homeostasis, which involves the nutrient acquisition, availability, and replenishment in the soil through biogeochemical cycles. Furthermore, Si is implicated in modulating ethylene-dependent and jasmonate pathways, as well as other phytohormones, particularly under stress conditions. Crosstalk between Si and phytohormones could lead to improvements in Si-mediated crop growth, especially when plants are exposed to stress. The integration of Si with reactive oxygen species (ROS) metabolism appears to be a part of the signaling cascade that regulates plant phytohormone homeostasis, as well as morphological, biochemical, and molecular responses. This review aims to provide an update on Si interplays with ROS, phytohormones, and other signaling molecules that regulate plant development under stress conditions.

AB  - Aims Although silicon (Si) is known to increase plant resistance to metal toxicity stress, the mechanisms responsible for alleviation of copper (Cu) toxicity are still insufficiently clear. We investigated the role of Si on Cu-binding processes involved in buffering excessive Cu in cucumber (Cucumis sativus L.) tissues. Methods Cucumber plants were subjected to moderate Cu toxicity stress (10 mu M Cu) without (-Si) or with (+Si) supply of 1.5 mM Si. We analyzed total and cell wall concentrations of Cu and Cu-binding compounds (organic acids and Cu-proteins) along with parameters of oxidative stress (e.g. lipid peroxidation and lignification). Results Supply of Si decreased total Cu concentration in both root and leaf tissues, but increased the root cell wall Cu fraction. Also, Si increased superoxide dismutase (SOD) activity in 10 mu M Cu-treated plants. Concomitantly, protein levels of Cu/Zn SOD isoforms (CSD1 and CSD2) in root tissues also increased in +Si plants. The leaf Cu-binding compounds, such as aconitate and plastocyanin (including the expression of CsPC gene) were higher in the +Si plants. Consequently, Si supply effectively lowered lipid peroxidation in both roots and leaves of Cu-stressed plants. Conclusions Supply of Si enhanced both the accumulation of Cu-binding molecules (Zn/Cu SOD in roots; aconitate and plastocyanin in leaves), and the Cu-binding capacity of the root cell wall.
