Summary: This study reassesses the systematics of the genus Juncus using genomic data and demonstrates the potential of comparative genomic analyses for understanding plant systematics and evolution. The results reveal the importance of repeat sequences in clarifying plant systematics and suggest an ancient hybridization event in the divergence of Juncus. The study also confirms the monocentricity of Juncus and identifies specific repeatome trends correlated with ancient origin.

Summary: The study found that adding flax pomace affected the expansion ratio, color lightness, and mechanical properties of extruded snacks. Sensory analysis showed no significant differences between snacks with 5% flax pomace and those without. However, adding more than 10% flax pomace made the product unacceptable to the panelists. There was also no significant difference between common flax and golden flax pomace in most traits, except for color.

Summary: In recent years, frequent extreme climates, especially high temperatures, have posed a growing threat to crop production. Flax, a crop suitable for cool environments, is greatly impacted by temperature in terms of fiber formation. However, our understanding of the regulatory effect of high-temperature (HT) stress on flax fiber development at the RNA level is limited. In this study, we investigated the molecular-level impact of HT stress (30 degrees Celsius) on flax fiber development by selecting three stages of fiber development and utilizing transcriptome sequencing. We observed different effects of HT stress on fiber cell development in each stage and identified a key gene, Lus10007349 (XTH), involved in fiber cell expansion and cell wall thickening, as a candidate gene for future research.

Summary: Non-coding repetitive DNA, dominated by transposable elements (TEs) and satellite DNA, plays an active role in the structure, evolution, and function of the nuclear genome. This study explores the relationship between changes in repetitive DNA and responses to a harsh environment in plants from the Cape Floristic hotspot. The findings suggest that the transition from Succulent Karoo to Fynbos environments is accompanied by a burst of TEs, which may contribute to phylogenetic divergence. The analysis of rapidly evolving repeatome could serve as an important proxy for understanding lineage divergence in rapidly radiating groups.

Summary: Seed size is a crucial factor in determining crop yields. A study on flax revealed multiple genes that regulate seed size through phytohormone pathways and transcription factors. Additionally, 54 differentially expressed genes associated with seed size and weight were identified. Nucleotide diversity analysis showed that some seed size-related genes were selected during flax acclimation.

Summary: In this study, a high frequency missense variant p.H102R in the SDHD gene was found in an extended cohort of Russian HNPGL patients using whole-exome sequencing. The variant was associated with somatic loss of the gene wild-type allele and evident LOH at the 11p15.5 region and potential loss of the whole of chromosome 11. These findings help with understanding the mechanism of tumorigenesis and are important for the development of cost-effective genetic screening programs.

Summary: Flax is globally cultivated for its seeds and fiber. Varieties of linseed are used in various fields depending on their composition of linolenic and linoleic fatty acids. Three different approaches were proposed to identify low-LIN mutations in flax varieties, and they showed promising results in testing. These approaches can be utilized in marker-assisted selection for breeding and basic research on the molecular mechanisms of fatty acid synthesis in flax seeds.

Summary: Malignant middle ear paraganglioma (MEPGL) is a rare neuroendocrine tumor. A case of malignant MEPGL was studied using comprehensive genetic analysis. A germline pathogenic mutation in the SDHB gene was identified, along with five novel somatic variants. The analysis showed the presence of specific mutation signatures and revealed the importance of SDHB mutation combined with loss of heterozygosity in tumor initiation and progression. These findings enhance our understanding of the molecular genetic mechanisms associated with this rare tumor.

Summary: Torin-2 is a highly selective inhibitor of TORC1 and TORC2 complexes, which can be used as an alternative to rapamycin. It has lower concentrations and fewer side effects than rapamycin. Our study evaluated the transcriptomic changes induced by Torin-2 in the heads of fruit flies and suggested possible neuroprotective mechanisms. Torin-2 had a slight positive effect on the lifespan of male flies but no positive effect on females.

Summary: Radical prostatectomy is the gold standard treatment for prostate cancer, but complete cure is not always achieved and recurrence is common. The current methods for assessing prognosis and choosing treatment strategies in PCa patients are not sufficient and new markers are needed. This study used RNA-Seq to identify potential prognostic markers at the gene expression and miRNA levels associated with cancer aggressiveness. The expression of candidate markers was validated and the predictive value of different marker combinations was analyzed using machine learning algorithms, with the CST2 + OCLN + pT model showing the highest potential (AUC = 0.863) based on CatBoost Classifier algorithm.

Summary: This study estimated the epigenetic age of long-lived individuals and found that their epigenetic age was significantly lower than their chronological age, indicating a slowing of aging. However, there were no significant differences in epigenetic age between healthy long-lived individuals and those with frailty, and no differences in epigenetic age were observed based on sex. The study emphasizes the need for further research on the epigenetic status of centenarians.
