Summary: The study demonstrates that SlBIM1a in tomato acts as a negative regulator in fruit development, governing the transcriptional regulation of growth-related BR target genes through its interaction with SlBZH1. This function depends on the recipient species and may be involved in auxin and light signaling.

Summary: This study analyzed the spatiotemporal distribution of Tomato brown rugose fruit virus (ToBRFV) in commercial tomato greenhouses and found that logistic models best described the temporal progress of the virus. The disease exhibited slightly aggregated patterns in the initial phase, highly aggregated in the exponential phase, and uniform in the deceleration and stationary phases, with important implications for disease monitoring, diagnosis, management, and risk prediction.

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 SIMYB75 gene plays a crucial role in tomato trichomes, with down-regulation increasing trichome formation and tolerance to spider mites, while overexpression inhibits these processes. The perturbation of SIMYB75 affects multiple transcriptional circuits, resulting in changes in trichome density and metabolic content.

Summary: This study explores the role of the SUPERMAN gene in tomato fruit and flower development. The researchers identified and characterized a mutant with abnormal fruit and flowers, and found that this mutant had a nonsense mutation in a gene similar to SUPERMAN. The study provides insights into the conservation and diversification of SUP genes in different species, and suggests that the FMF gene could be a potential target for yield improvement in tomato through genetic engineering.

Summary: Storage at low temperatures is a common practice to prolong the postharvest life of fruits and vegetables. This study investigates the response of tomato fruit to postharvest chilling stress. Screening of a tomato population revealed significant variations in chilling tolerance, and weight loss, chlorophyll fluorescence parameters, and performance index were identified as efficient markers for evaluating chilling response in postharvest fruit.

Summary: Microbial communities associated with plants play a vital role in plant growth regulation and disease control. This study investigated the effects of preharvest treatment with Aureobasidium pullulans S2 on the fungal and bacterial communities on tomato surfaces, and found that it significantly altered the microbial composition and potentially beneficial genera. Further research is needed to understand the functions of these taxa and utilize them for targeted microbial manipulation in fruits and vegetables.

Summary: It has been found that the NAC transcription factor NOR-like1 regulates fruit size in tomato by controlling the number of cell layers and cell area. Overexpression of the NOR-like1 gene reduces fruit weight and size, while knockout of NOR-like1 increases fruit weight and size. At the molecular level, NOR-like1 binds to the promoters of SlGRAS2, SlFW3.2, and SlFW11.3 to repress their transcription, while it also binds to the promoter of ARF9 to activate its transcription. These findings enhance our understanding of the transcriptional network that regulates fruit size in tomato.

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: This study reveals that JA signaling inhibits the growth and alters fruit quality of tomato seedlings, while TOR signaling positively regulates their growth and development. SlMYC2 mediates the interaction between JA and TOR signaling by acting on the promoter of SlTOR.

Summary: Research showed that fungi from the Trichoderma genus can promote plant growth and improve fruit quality in organic tomato cultivation, with a more significant effect on the Gruzanski zlatni cultivar. By altering the nitrogen balance index in leaves and fruit composition, Trichoderma fungi can induce plant secondary metabolism and increase flavonoid content in fruit.

Summary: Calcium chloride, chitosan, hydrogen peroxide, and ozonated water were studied for their effects on the storage ability and quality of tomato fruit, with chitosan and calcium chloride identified as the most effective treatments. The study also found that ascorbic acid and total carotenoids play a vital role in maintaining tomato fruit quality during storage.

Summary: Changes in gene expression are crucial for responses to abiotic stress. Transcriptome profiling of heat- or cold-stressed maize genotypes reveals many alterations in transcript abundance. By analyzing expression responses in multiple genotypes and identifying cis- or trans-regulatory variation, predictive models of gene expression responses for thermal stress-responsive genes can be developed. Models focusing on unmethylated regions near the transcription start sites (TSSs) show improved accuracy, suggesting that different genes may have varying response dynamics to stress.

Summary: This article discusses the importance of liquid chromatography-mass spectroscopy (LC-MS) in biological research and the challenges posed by technical errors. A new approach called pseudoDrift is proposed to detect and correct these errors, with demonstrated effectiveness and flexibility through data simulation. The analysis of a phenolic compound dataset from non-transgenic maize inbred lines showcases the application of this method in studying the dynamics of specialized metabolism in plants.

Summary: Maize production systems heavily rely on managed inputs, such as fertilizers, to maximize growth and yield. This study investigates the physiological responses of maize hybrids to nitrogen (N) supplementation in field conditions. The results reveal that maize perceives the lack of N as a stress and responds to N supplementation with prolonged vegetative growth. The study also identifies potential biomarkers of N status.
