Summary: This study compared the effects of osmotic, salt, and combined stress on the morphology and anatomy of photosynthetic organs in young quinoa plants. The results showed that salt stress of 100 to 200 mM NaCl did not have a critical impact on the growth of quinoa plants, while the plants were able to withstand salt stress at an intensity of 300 mM NaCl. However, adaptation mechanisms were violated at a salt stress intensity of 200 mM NaCl, and significant changes in water balance were observed at 300 mM NaCl, possibly due to damage to cell structures.

Summary: We studied the stress response mechanism of quinoa, a dicotyledonous cereal, by subjecting it to different stress treatments. Through high-throughput sequencing, we identified known/novel genes and miRNAs in quinoa, and predicted their target genes involved in stress response. Our findings showed that reactive oxygen species homeostasis, hormone signaling, cell wall synthesis, transcription factors, and other factors play important roles in the abiotic stress response of quinoa.

Summary: This study identified twelve YABBY genes in the quinoa genome and discovered their important roles in lateral organ development and abiotic stress responses. These genes contain cis-regulatory elements involved in various biological processes, and their expression is regulated under different stress conditions. Furthermore, functional conservation and divergence among these genes were observed. Overall, these findings provide a foundation for understanding the functions of YABBY genes in quinoa growth, development, and stress responses.

Summary: Soil salinization is a global problem that affects crop yields and agricultural development. This study investigates the role of auxins and expansins in the salt tolerance of quinoa, a halophyte plant. The results show that auxins contribute to quinoa's salt tolerance by promoting the accumulation of photosynthetic pigments, maintaining antioxidant systems, and scavenging excess reactive oxygen species. The study also identifies genes involved in the salt tolerance regulatory network of quinoa, providing new insights into salt tolerance mechanisms.

Summary: Research found that tobacco leaves exhibit significant leaf movements and detoxify sodium ions through the release of cellular water under salt stress. Tobacco leaves can recover quickly after salt stress, and this recovery process depends on plasma membrane hydrogen ion pumps and vacuolar ion exchange. Unlike roots, salt stress signaling and processing in tobacco leaves do not rely on calcium signaling.

Summary: This review summarizes the current knowledge of how hormones play essential roles in plant responses to boron and how they affect plant growth and development. Hormones are found to mediate the physiological disorders caused by boron deficiencies and excesses. Boron deficiency inhibits root elongation, while boron excess induces the production of reactive oxygen species. Plants adapt to boron deficiency and toxicity through the modulation of hormone production and signaling.

Summary: This study investigated the responses of Chenopodium album to heat, drought, and salinity stresses under field conditions. The results showed that C. album performed best when irrigated with 100 mM salt concentration and had higher drought tolerance. Despite accumulating high levels of Na and Cl ions in their leaves, physiological parameters were not significantly affected. However, when combined and prolonged, the plants exhibited similar levels of stress and no statistical variations were detectable. Shading mitigated the negative impact of salinity and drought stresses. Overall, it is concluded that combined stresses have a noticeable negative impact on C. album, but heat and drought stresses can be alleviated by shade.

Summary: Osmotic stress from salinity and drought negatively affects crop production, and there is a need to develop stress-tolerant crops with higher water use efficiency. Improving water use efficiency can be achieved by reducing stomatal transpiration without compromising CO2 uptake under osmotic stress conditions. Manipulating stomatal density holds promise as a strategy to enhance water use efficiency.

Summary: The epidermal bladder cells (EBCs) on the surfaces of quinoa and common ice plant were previously believed to be key to their salt and drought tolerance, but this study reveals that EBCs actually play minor roles in abiotic stress tolerance and may even be detrimental under water deficit conditions. Instead, EBCs function as deterrents to arthropod herbivores and provide protection against phytopathogens.

Summary: All plants have electrical excitability, but only few can produce a well-defined action potential (AP). The Venus flytrap Dionaea muscipula is able to generate APs with a high firing frequency and speed, allowing it to catch small animals quickly. The captured prey triggers a certain number of APs, which influences the trapping decisions made by the flytrap. The typical Dionaea AP lasts 1 second and consists of five phases, each controlled by specific ion channels, pumps, and carriers.

Summary: Plant transpiration is regulated by stomata, which are controlled by S- and R-type anion channels. Arabidopsis mutants lacking the ALMT12/QUAC1 R-type anion channel exhibit only a partial reduction in R-type channel currents. The molecular nature of these remaining R-type anion currents is still unknown.

Summary: This paper examines the evolution and function of the regulatory layers of the autoinhibitory region of P2B autoinhibited Ca2+-ATPases and finds that their evolution in animals and plants is independent. The paper also hypothesizes that the appearance of these regulatory layers may be linked to the multicellularity of animals and the transition of plants from water to land.

Summary: Drought and salt exposure have significant effects on water relations and nitrogen metabolites in leaves and roots of date palm seedlings. Water deprivation decreased total C concentration and increased total N concentration in roots, while salt exposure initially decreased total C concentration and increased total N concentration in roots, but increased total C concentration in leaves upon prolonged exposure. Both treatments resulted in the accumulation of most amino acids, indicating their role as compatible solutes in response to salt and drought stress in the roots, but not in the leaves. These findings highlight the differential impact of water deprivation and salt exposure on N metabolism in date palm seedlings.

Summary: This study revealed the important role of GADs in maintaining ROS homeostasis in guard cells, likely through a Ca2+-mediated pathway. The loss of GAD1, GAD4, and GAD5 in gad2 leaves increased GABA deficiency and resulted in increased cytosolic calcium and ROS accumulation in guard cells. Complementation with GAD2 or the application of ROS inhibitors restored the greater stomatal apertures of gad1/2/4/5, emphasizing the complexity of GABA's role as a guard-cell signal.
