Summary: Continuous light or predominant nitrogen supply as ammonium can induce leaf chlorosis and inhibit plant growth. Strong stress from CL and exclusive NH4+ supply synergistically inhibit growth, while mild stress enhances accumulation of stress hormones like jasmonic acid and ACC. This modulation of hormonal composition plays a potential role in plant growth responses to combined CL and NH4+ application.

Summary: Fruit formation is dependent on successful fertilization and is susceptible to weather fluctuations affecting pollination. The auxin hormone plays a role in fruit initiation and growth after fertilization. This study examines the regulation of fruit set and growth by the ARF family in tomato and Arabidopsis, and demonstrates that reducing the activity of SlARF8 genes can improve yield stability in fluctuating temperatures.

Summary: The study indicates that LED lighting at 385 nm can enhance the establishment of N. tenuis releases on tomato plants infested with B. tabaci. The results show that LED lighting has no effect on whitefly densities in the absence of predators, but significantly reduces whitefly densities when combined with N. tenuis releases. In a cooler environment, the LED lighting treatment maintains lower whitefly densities and higher predator densities in the crop.

Summary: Defense responses in tomato plants against pathogens are influenced by factors such as daytime and ethylene, with different levels induced at different times. Early biotic signaling in flg22-treated leaves and distal ones is an ethylene-dependent process that is also determined by the time of day and inhibited in the early night phase.

Summary: Bacillus thuringiensis (Bt), commonly used as a biological control agent, can persist in tomato plants and reach the fruits until consumption. Nearly half of the tomato samples tested positive for presumptive B. cereus, with 98% of these isolates identified as Bt.

Summary: Plants have developed defense mechanisms against environmental stresses through hormone signaling, with jasmonic acid (JA) playing a major role. JASMONATE ZIM-DOMAIN (JAZ) proteins regulate JA signaling, affecting plant responses to biotic and abiotic stresses. This study focuses on the functional role of a specific JAZ gene, CaJAZ1-03, in pepper. Results show that CaJAZ1-03 negatively regulates ABA signaling and drought responses, with protein stability modulated by CaASRF1 via the ubiquitin-26s proteasome pathway.

Summary: Waterlogging-induced hypoxia in the root zone leads to adaptive responses in the shoot, such as leaf epinasty. This study analyzed the dynamics of multiple hormones in tomato leaves during waterlogging, revealing that leaf age determines hormone homeostasis and modulates changes during waterlogging. Early hormonal signals, including ethylene and abscisic acid, were found to induce epinasty, while the balance of indole-3-acetic acid and cytokinins in the petiole ultimately regulates differential growth.

Summary: Neurodegenerative diseases are a heterogeneous group of diseases that affect the nervous system. Clinical diagnosis of these diseases is challenging due to their variability and overlapping symptoms. This study aimed to identify biomarkers in the cerebrospinal fluid and serum that can aid in the differential diagnosis and differentiation of specific neurodegenerative diseases. The results suggest that the proposed biomarkers can be useful for distinguishing between certain types of neurodegenerative diseases.

Summary: This research presents a highly sensitive method for the reliable determination of seven OPDA-aa compounds in plants. The method was optimized for extraction, sample clean-up, and final analysis. Five endogenous (+)-OPDA-aa were identified and their levels were estimated in mechanically wounded Arabidopsis thaliana leaves, with a peak observed 60 minutes after the wounding. The synthetic and analytical methodologies developed in this study will contribute to the understanding of the biological significance of these metabolites in plants.

Summary: Tree growth and survival rely on their ability to perceive and respond to environmental changes. This study found that ectomycorrhizal symbiosis can modify the signal responses of Populus trichocarpa to environmental changes and rewire molecular drivers of photosynthesis and the calcium signaling pathway. Additionally, ectomycorrhizas are less responsive to abiotic challenges compared to non-mycorrhizal roots.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

Summary: This study identified the high nitrogen use efficiency (NUE) black sesame variety 17-156 and analyzed its underlying physiological and molecular mechanisms. The results showed that 17-156 possesses a sophisticated nitrogen metabolizing machinery to uptake and assimilate higher quantities of inorganic nitrogen, simultaneously improving carbon metabolism and growth. Many important genes were up-regulated in 17-156 under high nitrogen condition. Additionally, 38 potential candidate genes were identified for future studies to improve sesame's NUE. These findings provide valuable resources for understanding the regulatory network of nitrogen metabolism and developing sesame cultivars with improved NUE.

Summary: Selenium (Se) can reduce uptake and translocation of cadmium (Cd) in plants by regulating root morphology. This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.
