Summary: Iron is an essential micronutrient for plant growth and development. Plants have evolved two different strategies, Strategy I and Strategy II, to acquire iron from soils. Recent findings show that the choice of strategy is influenced by soil characteristics, such as pH and oxygen concentration. This review summarizes recent research on plant iron uptake and discusses its impact on our understanding of plant iron nutrition.

Summary: Plant development is highly regulated by plant hormones and signaling pathways, with reactive oxygen species (ROS) playing an essential role as signaling molecules. ROS accumulation in plant roots helps maintain cell proliferation and differentiation balance for proper root growth. However, disruption of this balance affects how plants respond to environmental changes. The crosstalk between ROS and hormone signals, mediated by transcription factors, is crucial for regulating root growth and immune responses in plants.

Summary: Stomatal defences, mediated by apoplastic ROS, are vital for plants to prevent pathogen entry. This study sheds light on the role of NADPH oxidase RBOHF in the interplay between apoplastic and cytosolic ROS dynamics during stomatal immune response. Surprisingly, the rbohF mutant showed unexpected over-oxidation of the H2O2 sensor roGFP2-Orp1, while being impaired in PAMP-triggered stomatal closure and apoplastic alkalinisation.

Summary: Iron is an essential micronutrient for plants and animals, with deficiency leading to anemia in humans. Plants heavily rely on plant-based foods as their primary source of iron, but these foods are often poor sources of dietary iron. Understanding how plants adapt to iron deficiency is crucial for optimizing iron uptake and ensuring optimal plant growth.

Summary: Atmospheric pressure cold plasma (APCP) has great potential in improving crop production. This study investigates the regulation mechanism of APCP-generated reactive oxygen and nitrogen species (RONS) on intracellular redox homeostasis and plant growth. The results demonstrate that APCP treatment has a dual effect on Arabidopsis seedling growth, depending on the treatment time. APCP treatment leads to an increase in RONS in the liquid, conductivity, and oxidation reduction potential, and a decrease in pH. APCP treatment also causes an enrichment of intracellular RONS and an increase in malondialdehyde generation. Low-dose APCP treatment enhances intracellular antioxidants while high doses decrease their levels. These results highlight the importance of improved antioxidant capacity induced by moderate APCP-generated RONS in promoting plant growth.

Summary: Arabidopsis has approximately 2000 transcription factors in its genome, but their overlapping activities have made it difficult to analyze their functions. In this study, researchers generated inducible TF-GR lines in Arabidopsis to uncover clues to their function. By examining one of these TF-GR lines, they identified 13 novel TF candidates and investigated the regulating genes of two TFs showing higher anthocyanin accumulation under light conditions.

Summary: Apomixis, the transfer of maternal germplasm to offspring without fertilization, is a useful process in crop breeding. However, most apomictic plants still require pollination for endosperm development. This study shows that the expression of the ESP3-SRDX gene in Arabidopsis allows for ovule enlargement without fertilization. The unfertilized ESP3-SRDX ovules can partially nourish embryos and exhibit gene expression similar to fertilized seeds.

Summary: Tropospheric ozone has significant effects on the remobilization and allocation efficiency of aboveground biomass and nutrients in cereal crops. Long-term ozone exposure increases straw C:N ratio and affects grain C:N ratio. Grain N concentrations increase significantly under ozone stress, but N yield declines due to grain yield losses. Various indicators of N use efficiency are reduced, indicating reduced N absorption from soil and allocation from vegetative to reproductive organs. Straw C:N ratio is not suitable for predicting wheat productivity. Nitrogen harvest index (NHI) is not affected by ozone stress, but the relationship between harvest index (HI) and NHI is changed by elevated ozone concentration.

Summary: This study aimed to investigate the physiological response of broccoli leaves to abiotic stresses such as salinity and boron toxicity/deficiency. The results showed that the combined stress of salinity and boron deficiency resulted in a significant reduction in plant biomass, and the adaptation mechanisms were associated with water and boron concentration in the leaves. The expression patterns of PIP aquaporins varied among the different stress treatments, and their presence in the plasma membrane and interaction with the lipid environment played potential regulatory roles in facilitating salinity-boron stress adaptation mechanisms.

Summary: Plants activate a sophisticated signaling cascade in response to pests and pathogens, with lipids playing a crucial role in mediating these defense responses. Different types of lipids are involved in cell signaling during plant-pathogen interaction and each lipid has specific relevance and contributes to specific signaling cascades. Lipid biosynthetic enzymes, including phospholipases, are involved in the production of defense signaling molecules. Lipids participate in stress signaling by mediating signal transduction, acting as precursors for bioactive molecules, regulating ROS formation, and interacting with phytohormones.
