“…Nutrient deficiency directly restricts crop yield and quality, a common problem in agricultural production [ 93 ]. Increased ROS accumulation and oxidative damage have been frequently observed in different plant tissues following mineral nutrient imbalance [ 94 , 95 , 96 , 97 ]. For example, plants with low nitrogen levels experience serious lipid peroxidation and accumulate high levels of lipid-derived reactive aldehydes.…”

Aldehydes, derivatives of lipids, are ubiquitously produced through non-enzymatic and enzymatic pathways in higher plants and participate in many physiological and biological processes. Increasing evidence demonstrates that aldehydes are involved in plants response to many abiotic stresses, such as light, drought, heat and nutrient deficiency. In plant cells, endogenously triggered or exogenously applied high concentrations of aldehydes can damage proteins and nucleic acid, disturb redox homeostasis, and consequently inhibit plant growth; therefore, they are considered cytotoxins. Aldehyde levels are also used as biomarkers to evaluate the health status of plants. Further genetic research shows that several enzymes have strong capacities to detoxify these electrophilic aldehydes. Small molecules, such as carnosine and glutathione, also exhibit the ability to scavenge aldehydes, effectively promoting plant growth. Recently, increasing evidence has shown that certain aldehydes at certain concentrations can upregulate survival genes, activate antioxidant responses, increase defense against pathogens and stimulate plant growth. This review summarizes recent studies of lipid-derived aldehydes in higher plants, mainly focusing on the generation pathway, toxic effects, and detoxification strategies. In addition, the signaling effects of aldehydes in plants are also discussed.

“…Zinc is an essential nutrient for plants, because it is an important component of key protein structures and catalytic sites [6,7]. In plants, zinc has a significant effect on reactive oxygen metabolism and regulating defense reactions and signals [8,9]. Zinc deficiency reduces leaf biomass, increases ROS accumulation and affects plant hormone levels and TCA-related enzyme activities [9].…”

“…In plants, zinc has a significant effect on reactive oxygen metabolism and regulating defense reactions and signals [8,9]. Zinc deficiency reduces leaf biomass, increases ROS accumulation and affects plant hormone levels and TCA-related enzyme activities [9]. The leaves of Zn 2+ -deficient plants were notably yellow, and the levels of iron in their branches increased [6].…”

“…Moreover, concerning zinc deficiency, some enzymes such as alkaline phosphatase (ALP), alcohol dehydrogenase (ADH) and polyphenol oxidase (PPO) activity decreased, while guaiacol peroxidase (GPX) activity increased [11]. Zinc toxicity also induces reactive oxygen species (ROS) accumulation [9,12]. Zinc toxicity additionally significantly reduces plant biomass, inhibits the accumulation of other metal ions, reduces the photosynthetic rate and renders plants more susceptible to disease [12].…”

Although zinc and copper are the two essential nutrients necessary for plant growth, their excessive accumulation in soil not only causes environmental pollution but also seriously threatens human health and inhibits plant growth. The breeding of plants with novel zinc or copper toxicity tolerance capacities represents one strategy to address this problem. Glyoxalase I (GLYI) family genes have previously been suggested to be involved in the resistance to a wide range of abiotic stresses, including those invoked by heavy metals. Here, a MeGLYI-13 gene cloned from a cassava SC8 cultivar was characterized with regard to its potential ability in resistance to zinc or copper stresses. Sequence alignment indicated that MeGLYI-13 exhibits sequence differences between genotypes. Transient expression analysis revealed the nuclear localization of MeGLYI-13. A nuclear localization signal (NLS) was found in its C-terminal region. There are 12 Zn2+ binding sites and 14 Cu2+ binding sites predicted by the MIB tool, of which six binding sites were shared by Zn2+ and Cu2+. The overexpression of MeGLYI-13 enhanced both the zinc and copper toxicity tolerances of transformed yeast cells and Arabidopsis seedlings. Taken together, our study shows the ability of the MeGLYI-13 gene to resist zinc and copper toxicity, which provides genetic resources for the future breeding of plants resistant to zinc and copper and potentially other heavy metals.

“…Among heavy metals, zinc (Zn) represents an essential element for macroalgae, microalgae and higher plants [ 22 , 27 , 28 ]. Zn deficiency induces serious consequences in plants and seaweeds, including a reduction in photosynthetic yields and nitrogen uptake, but its excessive accumulation alters different physiological and metabolic processes [ 20 , 22 , 29 , 30 ].…”

Caulerpaceae are unconventional green algae composed of multinucleated, single siphonous cells. The species of Caulerpa are acquiring major scientific interest for both their invasion in the Mediterranean ecological niche and for the production of valuable natural metabolites. Furthermore, the abilities of Caulerpa spp. in the biorecovery of polluted waters were recently investigated. Among heavy metal contaminants in marine systems, zinc (Zn) is considered a critical pollutant, progressively accumulating from plastic leachates. In this study, the responses of Caulerpa racemosa to different levels (5–10 mg L−1) of Zn were studied for 14 days under laboratory-controlled conditions. Effects of Zn were monitored by measuring the growth rate, photosynthetic efficiency and gene expression. Moreover, the ability of Caulerpa to remove Zn from seawater was monitored. Zn induced detrimental effects by decreasing the relative growth rate (RGR) and maximal PSII photochemical efficiency (Fv/Fm). Moreover, C. racemosa, grown in contaminated seawater, reduced the levels of Zn to a final concentration of 1.026 and 1.932 mg L−1 after 14 days, thus demonstrating efficient uptake. Therefore, our results characterized the effects of zinc on C. racemosa and the possible role of this alga as being effective in the bioremediation of marine seawater.
