Summary: The CsGolS4 gene in cucumber is significantly induced by both cold and drought stresses, with CsGolS4-overexpression plants showing higher RFO contents and suppressed ROS levels, leading to increased tolerance to cold and drought stresses. Conversely, CsGolS4-RNAi transgenic plants exhibit increased vulnerability under stress conditions.

Summary: This study investigated the influence of phosphorus (P) on the formation of iron plaque on rice roots and its impact on cadmium (Cd) uptake. The results showed that while P supply enhanced the formation of iron plaque, it reduced the retention capability of Cd. Excessive P fertilizer application can lead to increased accumulation of Cd in rice plants.

Summary: This study evaluated the effects of climate change on the accumulation and bioavailability of Cd and Pb in rice plants and paddy soils. The results showed that climate change accelerated the accumulation of Cd and Pb in rice grains, increased the bioavailability of Cd and Pb in soil, and affected the composition of soil bacterial communities. It was also found that climate change significantly increased the carcinogenic risk for children and adults, posing a major risk to future safe rice production.

Summary: The study investigated the role of Fe and Mn in immobilizing Cd in soil and reducing Cd uptake by rice using X-ray photoelectron spectroscopy (XPS) characterization and chemical analysis. The results showed that Fe and Mn loaded on biochar (BC-FM) enhanced the removal of CaCl2 extractable Cd from the soil and Cd in pore water compared to BC. The excellent adsorption performance of BC-FM, enhanced by Fe-Mn oxides, reduced the available Cd in the soil and inhibited Cd accumulation in rice, resulting in increased rice biomass and Cd concentrations within the national safety standard.

Summary: This study investigated the effects of fertilization with iron on cadmium (Cd) uptake and distribution in rice. It was found that increasing the supply of iron significantly reduced Cd accumulation in the shoots by inhibiting Cd translocation from roots to shoots. Increasing the ionic soluble pectin (ISP) content and decreasing citric acid (CA) in the roots provided more Cd-binding sites in the cell wall, reducing the mobility of Cd in xylem. However, low iron or excess iron facilitated Cd uptake in rice roots. Soil fertilization with iron strongly reduced Cd accumulation in rice grain by immobilizing Cd in the roots.

Summary: The addition of Fe2+ (3 mM) was found to reduce the adsorption of CuO NPs (100 mg L-1) by rice plants, leading to a decrease in Cu uptake and accumulation in roots and shoots. Fe2+ induced the formation of iron plaque and altered metabolite levels, resulting in less Cu accumulation in rice plants exposed to NPs.

Summary: This study investigated the effects and interactions of radial oxygen loss (ROL) and iron (Fe) plaque on Cd accumulation in different water spinach cultivars. The results showed that a system composed of Fe plaque, ROL, and root Cd retention decreased Cd uptake and accumulation in water spinach. Low-Cd cultivars exhibited higher ROL, greater Fe plaque, and more effective root Cd retention.

Summary: Proper control and sensing of iron incorporation is crucial for maintaining foliar iron homeostasis, especially for the synthesis of chlorophylls and stability of the photosynthetic machinery in leaves. While the signaling of iron in roots has been extensively studied, the regulation of iron status in leaves remains to be further clarified.

Summary: Iron is an essential cofactor for all living organisms. The membrane transport mechanisms of iron often use ferrous ions, but uncoordinated or deliberated ferrous ions can initiate Fenton reactions. Fe-III citrate complexes are among the most important forms of iron, especially in plants where they can undergo photoreduction. The photoreaction of ferric species in leaves may have biological relevance in iron metabolism, although the specific relevance is not well understood.

Summary: In this study, the Blue/Clear-Native polyacrylamide gel electrophoresis (BN PAGE) method was improved by using a detergent mixture of 1% (w/V) n-dodecyl-beta-d-maltoside plus 1% (w/V) digitonin for solubilisation and 4.3-8% gel gradients for separation. Several large photosystem (PS) I containing bands were detected, and it was found that these bands were PSI-NADH dehydrogenase-like megacomplexes in maize bundle sheath thylakoids and PSI complexes with different light-harvesting complex (LHC) complements (PSI-LHCII, PSI-LHCII*) in mesophyll thylakoids of lincomycin treated maize. Proposed methods for quantitative determination and comparison of the complexes in different samples were also provided.

Summary: The study revealed that Thinopyrum obtusiflorum cv. Szarvasi-1 showed significant tolerance to zinc exposure, with shoot zinc content increasing significantly at a concentration of 1.9 mg g(-1) dry weight. High zinc exposures led to decreased potassium, magnesium, and phosphorus concentrations in the shoot, while manganese decreased in the root and iron content had a negative correlation with zinc in both shoot and root. The application of excessive EDTA affected zinc accumulation in roots and shoots due to competition between Fe-Zn for chelating phytosiderophores and root uptake transporters.

Summary: The uptake of iron by chloroplasts does not solely rely on photosynthetic functions, as demonstrated by the ability of etioplasts to acquire iron even in the absence of photosynthetic activity. This likely occurs through the internal reducing capacity of etioplasts supporting the reduction-based iron uptake.

Summary: In this study, three nanohematite/nanoferrihydrite preparations (NHs) with different coatings were applied through the roots and shoots to alleviate iron (Fe) deficiency in cucumber plants. The results showed that both root and foliar treatments improved chlorophyll content, biomass, and photosynthetic parameters, while reducing ferric chelate reductase activity. X-ray fluorescence mapping revealed that the applied NHs effectively accumulated Fe in the developing leaves and distributed it in the veins, indicating long-distance mobilization. These findings highlight the potential of NHs as nanofertilizers on a larger scale.

Summary: Haberlea rhodopensis is a unique resurrection plant that can survive in both shady and sun-exposed habitats, as well as freezing temperatures. This study aimed to investigate the proteomic changes associated with desiccation and freezing survival mechanisms in different ecological types of H. rhodopensis. The results revealed that drought-induced desiccation and low temperature stress trigger similar responses, but there are natural variations in the protective mechanisms between shade and sun plants. This finding highlights the importance of pre-conditioning effects for successful stress recovery.
