Summary: In this study, the characteristics of the SlTLP family were investigated, revealing their important role in plant growth and development. The SlTLP genes were classified into two subgroups, with the members containing the F-box domain renamed as SlTLFPs. Most of the SlTLP proteins were localized in the nucleus, and their expression was found to be influenced by biotic and abiotic stress. Furthermore, the members with an F-box domain were shown to interact with specific proteins to form complexes and function as E3 ligases through the F-box domain.

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: The Heirloom Golden tangerine tomato variety, rich in tetra-cis-lycopene, has high nutritional value and anti-inflammatory effects. The photoisomerization of tetra-cis-lycopene in the roots of the tomato plant affects root to shoot biomass, mycorrhizal colonization, abscisic acid accumulation, and responses to drought.

Summary: The study identified 31 SlBBX genes in tomato plants that are highly responsive to light, hormones, and stress conditions, playing important roles in improving cold tolerance. Disruption of specific SlBBX genes suppressed cold tolerance in tomato plants and impaired photosynthetic response after cold stress.

Summary: The study found that type IV glandular trichomes have an impact on host selection and proliferation of the aphid Macrosiphum euphorbiae, with aphids avoiding and showing impaired multiplication on genotypes with trichomes. Exposure to type IV glandular trichomes resulted in the overexpression of detoxication markers, repression of energetic metabolism, and activation of the ecdysone pathway, indicating key adaptations and metabolic trade-offs in aphids exposed to glandular trichomes.

Summary: This study evaluated the resistance and agronomic potential of newly identified eggplant accessions as rootstocks for tomato grafting, showing promising results in managing bacterial wilt. The new eggplant rootstocks have the potential to be alternative options for current rootstocks used in commercial tomato production.

Summary: Drought stress is a major factor affecting agricultural production by negatively impacting plant growth and metabolism. Previous research has shown that viruses, such as the tomato yellow leaf curl virus, can enhance a plant's ability to tolerate both drought and heat stress. However, the underlying mechanisms for this induced drought tolerance need further investigation.

Summary: This study reveals the genetic control mechanism of the orange-fruited phenotype in a tomato elite inbred line. It is found that this phenotype is controlled by a single recessive gene, oft3, which leads to reduced carotenoid levels and an increased beta-carotene-to-lycopene ratio in fruit. The candidate gene SlIDI1, with a 116 bp deletion mutation, is identified through gene mapping and genome sequence analysis. Functional complementation and CRISPR-Cas9 knockout experiments confirm the role of SlIDI1 in controlling the oft3 locus. Further analysis shows that SlIDI1 is highly expressed in flowers and fruit, and its expression increases with fruit ripening or flower maturation.

Summary: Resistance to Tomato Yellow Leaf Curl Virus is a major objective in tomato breeding programs. Breeders are interested in introgressing multiple resistance genes to increase resistance levels and prolong the longevity of resistant cultivars. Evaluations of commercial F1 tomato hybrids revealed that most hybrids have multiple heterozygous resistance genes. Genetic variability in traits related to tolerance, yield, and fruit quality allowed for selection of the best genotypes. The use of specific resistance genes will be valuable in breeding programs using marker-assisted selection techniques.

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. This discovery is important for understanding the regulation of stomatal movement.

Summary: Tomatoes are highly demanded in almost every country due to their gastronomic versatility and nutritional value. Factors such as drought, salinity, and inadequate temperature can decrease tomato yield and affect various metabolic pathways. Biotechnological tools can be used to alter tomato genes and improve its adaptability to abiotic stress. Biomimetic biotechnological approaches (BBA), which imitate nature's solutions, have gained attention for developing sustainable strategies to enhance tolerance in plants. In this review, genetic sequences and molecules that were targets of biotechnological intervention in tomatoes are discussed, along with the implications and perspectives within the GMO debate.

Summary: This study focused on the candidate gene for tryptophan decarboxylase (TDC) in tomato, SITDC1, revealing its role in biosynthesis and its impact on the growth and development of serotonin-rich fruits. The results demonstrated the importance of SITDC1 in producing fruits with high serotonin content and highlighted the role of serotonin in ripening.

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: Research showed that abaxial leafy supplemental lighting (AB) can enhance net photosynthetic rate and stomatal conductance in tomato plants compared to adaxial leafy supplemental lighting (AD). However, the underlying regulatory mechanisms remain unclear. In this study, transcriptomic and proteomic changes in tomato leaves were assessed under AB and AD, revealing differential expression of 7352 genes and 152 proteins. Significant differences were observed in genes and proteins related to various pathways, including cell processes, metabolism, regulation, genetic information processing, and organismal systems. The upregulation of key genes involved in hormone signaling, light perception, photosynthesis, plant fitness, and fruit ripening explained the positive effects of AB on plant growth and development. qPCR confirmed the upregulation of genes involved in auxin response, gibberellin synthesis, cell cycle regulation, sugar transport, and fruit ripening. These findings contribute to understanding plant light response mechanisms and identifying genes for efficient light energy utilization.
