Summary: Aluminium toxicity and phosphorus deficiency are major interconnected problems in modern agriculture. The ALMT family of membrane proteins in plants have been extensively studied for their physiological functions, such as tolerance to Al3+ and regulation of stomatal movement. This review provides a comprehensive summary of the current knowledge on ALMT proteins, their involvement in various physiological processes, and the regulatory mechanisms. The authors also present new insights into the molecular evolution of ALMT proteins and propose future research directions.

Summary: Iron deficiency in plants can lead to excessive absorption of zinc. This study reveals the mechanism of MdCAX3 mRNA transport from the leaf to the root, and its activation by MdCXIP1. MdCAX3 suppression increases root apoplastic pH associated with the iron deficiency response. Overexpression of MdCAX3 affects the apoplastic pH only in the presence of MdCXIP1. Furthermore, MdCAX3 is involved in zinc compartmentalization and plays a role in iron and zinc homeostasis.

Summary: ALMT1 is a protein in plants that mediates the transport of malate and plays a role in aluminum resistance in acidic soils. Its structure includes an anion channel with arginine residues for malate recognition. Aluminum binding induces structural changes that open the channel, allowing for malate transport.

Summary: This study critically discusses the direct and indirect effects of natural polyamines and their catabolites on the activity of key plant ion-transporting proteins, particularly in stress responses. The research predicts the role of polyamines in important cell ionic homeostasis and signaling, and summarizes several unresolved issues including the subcellular levels of polyamines and their mechanisms of action.

Summary: Cucumber plants can reduce the toxic effects of Cd through removing excess toxic ions and increasing the activity of PM H+-ATPase under cadmium stress. This process is influenced by the activity of DAO, which promotes the formation of NO through H2O2 production. The stimulating effect of Cd on PM H+-ATPase activity and expression of CsHA2, CsHA4, and CsHA8 genes can be inhibited by the DAO inhibitor AG.

Summary: This study demonstrates that altering the composition of root exudates can significantly change the root microbiome composition throughout the root system, but the root type, position along the roots, and soil type have a greater influence on microbiome structure than the exudates.

Summary: Chloride channels (CLCs) are vital proteins present in all life forms, with diverse functions from acid and fluoride tolerance in prokaryotes to muscle stabilization and neuronal development in mammals. In plants, loss of CLC function severely impairs cellular processes critical for growth and development, and they play significant roles in improving salinity tolerance and nitrogen use efficiency. Despite their importance, more in-depth studies on CLCs in plants are needed for potential applications in crop improvement.

Summary: Salinity affects the growth and photosynthesis of Avicennia marina, a mangrove plant. At 200 mM NaCl, the whole-plant dry weight and photosynthetic parameters increased, but decreased over 400 mM NaCl. High salinity caused reduction in starch grain size, swelling of thylakoids, separation of granal stacks, and even destruction of the envelope. The salt glands in the adaxial epidermis of the leaves excrete Na+ effectively below 400 mM NaCl, improving its salt tolerance.

Summary: The ROC3 gene encodes a CYP that positively regulates ABA-induced stomatal closure and the drought response by inhibiting ROS accumulation and modulating the expression of stress-activated genes. Mutants of roc3 show abnormal stomatal response and faster leaf water loss, while complementation lines exhibit similar characteristics to the wild type.

Summary: The opening and closing of plant stomata is regulated by light-responsive proteins and metabolic activities. A metabolite called 12-oxo-phytodienoic acid (OPDA) negatively regulates stomatal response to light, preventing excessive water loss. OPDA affects the activities of proton pumps and potassium channels, ultimately impacting plant growth and water use efficiency.

Summary: A spatial transcriptomics workflow was developed for studying gene expression during barley grain germination, revealing specific spatial expression patterns of functional gene categories. Over 14,000 genes were differentially regulated within the first 24 hours after imbibition, with certain genes showing focused expression within subdomains of the embryo over time, suggesting their role in establishing the embryo axis.
