Article Abstract
Tumor necrosis factor receptor-associated factor (TRAF) proteins, originally identified in mammals, have since been found in most plants. TRAF proteins in plants have been shown to be involved in cellular autophagy, immunity, drought resistance, and ABA induction. However, the role in regulating sucrose and starch metabolism has not been reported. In this study, we confirmed that can regulate sucrose and starch metabolism through gene editing, phenotypic observation, transcriptomics and metabolomics analyses. Initially, 200 and 81 TRAF proteins were identified in rapeseed ( L.) and , respectively, and divided into five classes. We found that overexpression of inhibited root length, plant height, flowering, and leaf development in . Additionally, 12 differentially expressed genes (DEGs) related to sucrose and starch metabolism pathways were identified in overexpressing and knockout plants, respectively. Six differentially accumulated metabolites (DAMs)-fructose, sucrose, glucose, trehalose, maltose, and 6-phosphate fructose-were identified using widely targeted metabolomics analysis. The results show that affects the growth and development of , and induces the expression of sucrose and starch synthase and hydrolases, providing a foundation for further research into its molecular mechanisms.

This study explores the role of α-Fe₂O₃ in improving extracellular electron transfer (EET) and symbiotic interactions between electroactive Shewanella oneidensis MR-1, its gene-deficient mutants (ΔmtrC, ΔomcA, and ΔcymA), and microalgae (Chlorella vulgaris). The iron oxide facilitates the efficient transfer of electrons generated by MR-1 to microalgal photosystem via the pathway of CymA-MtrC-OmcA to α-Fe₂O₃. This process enhances the removals of TOC, TN, and NH₄⁺-N in the MR-1 bacterial-algal consortium by 9.

While plants adapt to fluctuating phosphorus (P) availability in soils by enhancing phosphate acquisition or optimizing internal P-utilization, the spatiotemporal dynamics of these responses, particularly in crops, remain poorly understood. This study systematically investigated how and when potato organs respond to fluctuating P availability across different developmental stages using transcriptomic, metabolomic, and physiological analyses of leaves, roots, and tubers. Transcriptomic data revealed dynamic, organ- and stage-specific responses to P-deficiency, with the highest number of differentially expressed genes in leaves before tuberization and in roots during tuberization.

High semen quality is vital for reproductive success in the swine industry; however, seasonal fluctuations often compromise this quality. The molecular mechanism underlying these seasonal effects on semen quality remains largely unclear. This study employed untargeted metabolomic profiling of boar seminal plasma (SP) to identify metabolites and metabolic pathways associated with semen quality during the summer and winter months.

Nitrogen and auxin uptake plays pivotal roles in seed germination and development. Gastrodia elata, a fully mycoheterotrophic plant, depends entirely on its symbiotic association with Mycena for early growth and seed germination. The process by which Mycena enables the supply of nitrogen nutrients and auxin, which are deficient in G.
