Summary: The comparative structural and functional analysis of chitin-binding lectins from S. tuberosum and S. lycopersicum revealed high percentages of proline residues and differences in binding affinity towards different chitin oligomers. The study showed that the binding of glycans significantly improved the structural stability of STL and SLL. These findings provide insights into the potential therapeutic properties of STL and SLL, laying the foundation for further experimental studies.

Summary: The RTR complex is essential for genome stability in eukaryotes, with TOP3α and RMI1 mutants in tomato showing significantly different phenotypes compared to Arabidopsis. While the TOP3α mutant in tomato is embryo-lethal, the RMI1 mutant does not exhibit detectable defects in somatic DNA repair or meiosis. This differentiation of function in RTR complex partners between plant species suggests caution in generalizing knowledge obtained in Arabidopsis to the entire plant kingdom.

Summary: A newly discovered pectin-hydrolyzing enzyme gene, SlPG49, was cloned from a tomato and shown to be highly expressed during fruit softening, indicating its involvement in this process. Subcellular localization and enzymatic activity assays confirmed that SlPG49 is located in the cell membrane and wall and has the ability to catalyze the hydrolysis of polygalacturonic acid, providing experimental evidence for understanding the biological functions of plant PGs during fruit softening.

Summary: In this study, 18 AHL family genes were identified in the tomato genome, and their involvement in plant development and stress response was investigated. Six AHL members were found to be localized in the nucleus, indicating their importance in early fruit development. The clade A members showed greater responsiveness to heat, drought, cold, and salt stresses compared to clade B members, suggesting their major role in abiotic stress response. Overexpression of SlAHL1 and SlAHL7 in Arabidopsis increased sensitivity to ABA during seed germination and seedling stages, and inhibited seed germination while promoting primary root elongation under salt and drought stresses. This study highlights the importance of clade A SlAHL genes in abiotic stress response.

Summary: In this study, the physiological and electrophysiological properties of ALMT channels in Arabidopsis and tomato were analyzed. The findings suggest that the guard-cell-type ALMT channels are activated by extracellular organic acids and play a role in stomatal closure.

Summary: This study aimed to promote healthy and balanced lifestyle through increased sustainable production and consumption of fruits and vegetables, comparing the effects of field vs. plastic tunnel growing systems on organic improved tomato genotypes. Results showed higher values of ascorbic acid in field-cultivated tomatoes, while beta-carotene and lycopene content were higher in genotypes grown under plastic tunnel conditions. Significant statistical differences were observed in most parameters between cultivation conditions, highlighting the importance of selecting genotypes that respond positively to organic cultivation in terms of antioxidant compounds.

Summary: In this study, we introduced the genetic determinants controlling type-IV trichome development from S. galapagense into cultivated tomato plants and created a line named MT-Get. However, the density of type-IV trichomes in MT-Get was low and did not result in high levels of acylsugars production, indicating that type-IV trichome development alone is not sufficient for insect resistance.

Summary: The study demonstrates that a series of acylhydroquinone compounds exhibit strong antiplatelet effects, with compound 38 showing the highest activity by significantly inhibiting multiple platelet aggregation pathways. Its mechanism of action involves reducing a central target in human platelet activation, leading to a lower response of platelets to activating agonists. This research highlights the potential of acylhydroquinone compounds as promising candidates for antiplatelet drug development in the future.

Summary: This study showed that aqueous extracts of leaves and fruits of pink guava and Costa Rican guava can inhibit platelet aggregation induced by various agonists, and reduce secretion of P-selectin and activation of GP IIb/IIIa. These extracts are a rich source of phenolic compounds, mainly quercetin aglycones and proanthocyanidins, which could potentially be beneficial for preventing thrombotic events.

Summary: The study evaluated the antiplatelet effect of isorhamnetin and found that it significantly inhibits platelet aggregation induced by collagen and TRAP-6, without showing cytotoxic effects. Isorhamnetin decreased ATP levels in stimulated platelets and inhibited mitochondrial function, demonstrating its potential antithrombotic effect. The findings support the presence of antiplatelet and antithrombotic properties of isorhamnetin in daily consumed foods.

Summary: Oxidative stress is involved in various non-communicable diseases, such as cardiovascular diseases. Excessive reactive oxygen species (ROS) formation can lead to the undesirable effects of oxidative stress. Platelets play a crucial role in arterial thrombosis, and excessive ROS formation stimulates platelet activation and aggregation. The proteins Protein Disulphide Isomerase (PDI) and NADPH oxidase (NOX) isoforms are involved in these processes. A bioinformatic analysis of their roles and interactions in platelets, as well as the signaling pathways involved, was performed. The data support the potential use of specific enzyme inhibitors or dual inhibition of these enzymes for treating diseases involving platelet dysfunction.
