Summary: Citrus productivity in the Mediterranean basin has been declining due to climate change and high salinity levels in the aquifers. The rootstock has been found to play a crucial role in stress tolerance, but the scion also has an important impact. The study demonstrates that a versatile photosynthetic system, appropriate stomatal density, and modulation of genes encoding Cl- transporters are important for citrus tolerance to high salinity.

Summary: This study aims to investigate the effects of single or combined salinity and drought stresses on physio-biochemical and molecular status of diverse forage pea genotypes. The results showed that the genotypes O14 and T8 were more tolerant to combined stress by activating antioxidative enzymes, endogenous hormones, stress-related genes, and leaf senescence genes. These genotypes could be used to develop pea plants that tolerate salinity or drought stress conditions.

Summary: Strigolactones (SLs), as novel phytohormones, play a crucial role in enhancing plant tolerance to abiotic stresses by responding to nutrient deficiency, drought, high temperature, and light stress. They assist in initiating physiological responses and mediating the interaction with soil microorganisms, attracting beneficial microorganisms and providing essential elements to roots. In addition to their role in stress resistance, SLs also affect photosynthesis, bridge other phytohormones, and induce metabolic compounds.

Summary: Phyto-hormones in plants are crucial for regulating crop growth and yield, especially under salt stress. Recent studies have highlighted the significant role of exogenous hormones, such as gibberellin (GA) and salicylic acid (SA), in regulating cotton's response to salt stress. However, a comprehensive understanding of the mechanisms by which these hormones regulate growth and yield under salt stress is still lacking.

Summary: Triclosan (TCS) is a widely distributed antibacterial agent, and its high concentration in sludge can cause physiological damage to plants. Little is known about the physiological and molecular mechanisms of TCS in plants. Research has shown that TCS treatment leads to decreased germination rate, root development, photosynthesis efficiency, and increased ROS accumulation in tobacco plants. Transcriptome analysis revealed differential gene expression mainly enriched in plant hormone signal transduction pathways in response to TCS stress. Transgenic tobacco overexpressing a salicylic acid binding protein gene exhibited enhanced antioxidant enzyme activities and TCS resistance, highlighting the important role of the SA signal pathway in TCS response in plants.

Summary: Plants respond to environmental stresses by transmitting long-distance signals and changing hormone levels. Long-distance electrical signals, induced by local stimulation, regulate hormone levels and interact with phytohormones. This review provides insights into the interactions between electrical signals and phytohormones, highlighting important integration nodes involving changes in pH, Ca2+, and ROS levels, and gives an overview of how electrical signals and hormones work together to induce a systemic response.

Summary: Salinity is a common factor that limits crop productivity. The negative effects of salt stress on plant processes are caused by osmotic stress and toxic ions. The study investigated how salinity affects photosynthesis, transpiration, water content, and cytosolic pH in tobacco and potato plants. Salinity decreased photosynthesis activity and led to a decrease in water content and transpiration. The cytosolic pH also decreased in tobacco and potato plants. The study analyzed potential mechanisms of the effects of salinity on photosynthesis.

Summary: This study investigated the mechanisms of systemic functional responses induced by electrical signals. It was found that chronic beta-irradiation had a positive effect on the morphometric parameters and photosynthetic activity of tobacco plants. Irradiation enhanced the plant's response to electrical signals, resulting in temporary changes in chlorophyll fluorescence parameters and increased amplitude and leaf coverage. Irradiation also enhanced signal-induced cytoplasmic acidification and showed stronger inhibition of stomatal conductance in the plants. The study concluded that the effect of irradiation on the systemic response induced by electrical signals mainly occurs during the transformation stage.

Summary: Electrical signals in plants are generated in response to various stressors and can greatly affect different physiological processes. These signals play a crucial role in integrating plant responses to stress, but they may also cause temporary separation between cells or plant parts. This separation can have adaptive benefits by storing energy compounds, limiting damage propagation, and potentially triggering programmed cell death.

Summary: Salinization is a significant factor that limits agricultural plant productivity. Multispectral imaging and the photochemical reflectance index (PRI) can be used to detect early changes in plants under salinization. In this study, we investigated the sensitivity of modified PRIs to changes in pea plants under salinization treatment. The results showed that long-wavelength PRIs decreased, while short-wavelength PRIs increased under salinization. Long-wavelength PRIs were found to be more sensitive to plant changes and could potentially be used as a universal tool for early detection of stress in plants.

Summary: Photodamage is a key mechanism of photosynthetic disruption in plants under stress. Investigating photodamage is important for both basic and applied research. However, the complex mechanisms of photodamage make it difficult to use experimental methods, so developing mathematical models and conducting model-based analysis can overcome these limitations. In this study, a modified Farquhar-von Caemmerer-Berry model was developed to describe photodamage of photosynthetic electron transport in C-3 plants, using experimental results from pea plants. The model analysis showed that inactivation of linear electron flow and Rubisco can both increase and decrease photodamage. Simulation of photodamage under different temperatures and light intensities revealed multi-phase temperature dependences, with paradoxical increases in thermal tolerance observed under high temperatures. It was also found that changes in temperature optimums of linear electron flow and Rubisco can modify temperature dependences of photosynthetic electron transport under photodamage induction, mainly stimulating its photodamage.

Summary: Salinity has a significant impact on important processes in plants and decreases their yield. This study revealed that lower concentrations of NaCl result in cytosolic acidification in plant cells, while higher concentrations can cause an increase or return to normal levels of cytosolic pH. Additionally, salinity inhibits plant development and affects morphology-related parameters. The relationship between cell length and NaCl concentration is nonlinear.
