Summary: In plants, drought induces oxidative stress, but it can be alleviated by dimethylthiourea (DMTU) treatment. DMTU regulates the antioxidant system and redox control, protects the reducing potential, and suppresses ABA-mediated oxidative burst signaling through its antagonistic regulation with salicylic acid (SA).

Summary: The study demonstrates that putrescine (Put) regulates stomatal changes in cucumber leaves under salt stress by increasing endogenous PAs and H2O2 levels, decreasing ABA content, and promoting stomatal opening, photosynthesis, and plant growth. Inhibitors can affect this process.

Summary: Salinity stress adversely affects plant growth and development, limiting crop productivity. Plants adapt to salt stress by synthesizing, signaling, and regulating osmolytes and phytohormones. Osmolytes stabilize osmotic differences and facilitate protein functioning and stress signaling. Phytohormones play critical roles in plant adaptation to salt stress by regulating osmolyte accumulation and minimizing detrimental effects.

Summary: Salt stress is a major limiting factor for crop growth and yield, while nitrogen is essential for plant growth and has been reported to enhance salt tolerance. However, the interaction between salt and nitrogen in grapes is not well understood. This study found that moderate nitrogen supplementation can improve salt tolerance in grapes by regulating physiology, endogenous hormones, and signaling pathways.

Summary: Polyamine metabolism in plants is controlled by multiple genes which are differentially regulated under different physiological conditions. Our study in Arabidopsis thaliana revealed that most genes in polyamine metabolism are not responsive to exogenous polyamines, but there is a difference in response to polyamines between Arabidopsis and rice, as shown by the induction of OsPAO6 gene. These results provide a framework for further study of regulatory modules controlling the expression of each polyamine metabolic gene.

Summary: Drought stress can significantly reduce wheat growth and development as well as grain yield. This study investigated the morpho-physiological and hormonal responses of six winter wheat varieties to drought stress during stem elongation and anthesis stages and measured grain yield-related traits after harvest. The results showed that some varieties were more tolerant to drought while others were more sensitive.

Summary: This study revealed that grafting with pumpkin as a rootstock improved chilling tolerance in cucumber leaves. It increased the accumulation of salicylic acid, abscisic acid, and hydrogen peroxide. Salicylic acid participated in grafting-induced chilling tolerance by stimulating the biosynthesis of abscisic acid and hydrogen peroxide. Abscisic acid, as a downstream signaler of salicylic acid, mediated the salicylic acid-induced chilling tolerance in grafted cucumber plants.

Summary: During ripening, ABA regulates anthocyanin accumulation in fruit at the onset of ripening, while SA plays a role in stress-induced anthocyanin biosynthesis in response to biotic stress. The higher concentration of ABA in fruit skin is crucial for tissue-specific pigmentation during fruit development.

Summary: This study investigated the relationship between hormone levels, gene expression, and chilling injury in pepper fruit. 'TK' genotype was less sensitive to low temperature, while 'GG' genotype showed higher sensitivity, and GABA and CaARF19 were possibly associated with chilling injury levels.

Summary: It has been shown that moderate drought stress increases the susceptibility of Arabidopsis thaliana to bacterial pathogens, and that drought and bacterial stress antagonistically modulate a large set of genes through the SA and ABA signaling networks. Under combined stress, drought downregulates the induction of SA production through the ABA pathway, impacting plant defense against bacterial pathogens.

Summary: The application of kaolin particle film in grapevines was studied in two growing seasons to evaluate its effects on phytohormones, antioxidant defense, and oenological parameters. Results showed that kaolin delayed ripening processes under severe summer stress conditions and improved antioxidant defense and phytohormone balance in treated berries, with significant interactions observed between kaolin treatment, variety, and developmental stage in both assessed years.

Summary: Abscisic acid (ABA) is an important hormone in plants that regulates growth and development, with PYL proteins playing a central role in signal transduction pathways. In cucumber, 14 PYL genes were identified, showing specific expression patterns in response to different stresses. Some genes, like PYL8, may have a crucial role in abiotic stress responses.

Summary: In this study, the role of copper ions as a mediator of DNA sequence variation in the CHG context was highlighted while silver ions did not show any mediating effect. Modifications in in vitro culture conditions explained DNA sequence variation, demethylation, and de novo methylation in the CHG context. Incorporating copper ions in the induction medium should be approached cautiously.

Summary: The study on transgenic winter triticale in field experiments in central Poland reveals that factors such as temperature increase, wind strength, and direction have a positive impact on pollen grain dispersal. Lower amounts of transgenic pollen grains were observed at a distance of 85 meters, with potential migration distances up to 100 meters in extreme atmospheric conditions.

Summary: Cas endonuclease-mediated genome editing offers a long-awaited molecular biological approach for modifying predefined genomic target sequences in living organisms. The implementation of this technology can be challenging for species like triticale, but pre-validated cas9/gRNA constructs provide a strong foundation for the targeted induction of heritable modifications in triticale genes. The study also demonstrates that in-del induction frequency in triticale can be increased by TREX2 nuclease activity, regardless of gRNA performance.

Summary: The reconfiguration of primary metabolism is crucial for plant-pathogen interactions. This study compared the metabolic responses of cucumber leaves inoculated with Pseudomonas syringae pv lachrymans (Psl) and non-inoculated systemic leaves, revealing changes in nicotinamide adenine dinucleotides, soluble carbohydrates, carbohydrate metabolism-related enzymes, photosynthesis-related genes, tricarboxylic acid cycle metabolites, and enzyme activities. Psl infection resulted in altered [NAD(P)H]/[NAD(P)(+)] ratio, decreased glucose and sucrose contents, increased glucose turnover, and accumulation of specific metabolites. The infected leaves also showed enhanced tricarboxylic acid cycle activity and gene expression, and increased respiration rate. Changes in gene expression related to photosynthesis were consistent with a decline in net photosynthesis. Additionally, both common and specific metabolic changes were observed in infected and non-infected leaves, respectively. These systemic leaf metabolic changes were part of the global effects induced by local infection, contributing to growth-defense balance.
