Summary: By analyzing the transcriptome and metabolome of maize roots, this study investigated the effects of straw return and fertilization on root morphology. The results showed that straw return promoted root thickening, while fertilization increased root branching. These morphological responses were closely associated with transcriptional regulation and metabolism modulation, involving the activation or fine regulation of various genes and metabolites. These findings provide important insights into the growth-promoting effects of straw return and its impact on the transcriptional regulation and metabolism of maize roots, which can guide the appropriate utilization of crop residue resources in agriculture.

Summary: This study profiled five maize organs using different liquid chromatography-mass spectrometry methods and identified 427 compounds, including phenylpropanoids, flavonoids, benzoxazinoids, and auxin-related compounds. The analysis of candidate substrate-product pair networks revealed that phenylpropanoids are present in all organs, while other metabolic classes are organ-enriched. The findings provide important insights into the metabolic pathways and systems biology of maize.

Summary: The seed number and harvesting ability in maize are primarily determined by the structure of the female inflorescence, specifically the ear. This study investigated the molecular networks involved in ear morphogenesis in maize through transcriptomic analysis. Different stages of ear development were identified, and genes and transcription factors associated with these stages were identified. This study provides important insights into the gene activity and regulatory modules associated with ear development in maize.

Summary: In this study, the effects of different light qualities on grape morphology and physiology were investigated using multivariate sequencing analysis. Blue and red light significantly improved various parameters, but some parameters under blue light showed irreversible trends. Furthermore, blue and red light enhanced the contents of minerals in grapes. The study also revealed genes and transcription factors associated with secondary metabolite biosynthesis and photosynthetic pathways. Overall, this research provides new insights for viticulture and agricultural strategies.

Summary: Root exudates, plant-derived metabolites, play a crucial role in shaping root-associated microbiomes as nutrients and signals. This study investigates the dynamics of exudation and its correlation with changes in microbiome structure. The research suggests that collections of exudates should be conducted for hours rather than days, as some metabolite abundances saturate over time. Plant growth in different environments alters exudate profiles significantly. Moreover, different plant species exhibit distinct exudate metabolite profiles, but also share a core metabolome for tissues and exudates. Furthermore, exudate profiles show diurnal patterns. These findings provide important insights for future studies on plant-microbe interactions.

Summary: The study found that seed coating with zinc significantly reduces boron accumulation and toxicity in maize, and coating with boron, zinc, and boron+zinc leads to alterations in the expression of specific genes, with some co-modulated genes primarily encoding stress resistance- and membrane-related proteins.

Summary: This study analyzed the integrity of the dissimilation pathway in Pichia pastoris using transcriptomics and metabolomics for the first time. Blocking the dissimilation pathway significantly decreased the level of oxidative phosphorylation and weakened the methanol assimilation pathway, resulting in insufficient energy supply and carbon fixation, leading to inefficient biomass accumulation and genetic replication. Additionally, the transcriptional upregulation of proteasomes and autophagy may be a stress response to resolve formaldehyde-induced DNA-protein crosslinking.

Summary: Soil salinization is a global environmental problem that affects agricultural productivity. Recent research has found that histidine plays a crucial role in reducing reactive oxygen species (ROS) and improving plant tolerance to salt stress. This study investigated the regulatory effects of histidine on the root system of maize under salt stress. The results showed that histidine can ameliorate the adverse effects of salt stress on maize root growth by reducing the accumulation of ROS and increasing the activity of antioxidant enzymes. Transcriptome analysis revealed that histidine treatment enriched DEGs involved in plant hormone signaling, glycolysis, and nitrogen metabolism pathways, further enhancing the salt tolerance of maize roots.

Summary: This study investigated the mechanisms of salt adaptation in salt-tolerant rice HD961 at the early seedling stage using transcriptome and metabolome analysis. The results showed that HD961 exhibited stronger growth and antioxidant capacity under salt stress compared to 9311. The analysis revealed that glutathione metabolism played a critical role in HD961's response to salt stress. Intensive regulation of related genes and metabolites may contribute to the salt resistance in HD961.

Summary: Fusarium verticillioides is a threat to maize production due to its ability to infect maize kernel and produce fumonisins. Metabolic studies were conducted to uncover pathways involved in maize resistance to Fusarium ear rot and fumonisin contamination. Differences in membrane lipid homeostasis, methionine metabolism, and indolacetic acid conjugation were found to be relevant in distinguishing between resistant and susceptible inbreds. Specific metabolites such as spermidine and isoquinoline showed potential as indirect selection traits for improving resistance to Fusarium ear rot and reducing fumonisin accumulation.

Summary: Low temperature stress affects membrane lipid metabolism in maize seedlings, with major extraplastidic phospholipids dominating the root tissues. Genes related to lipid metabolism were significantly expressed under cold stress, particularly in pathways such as Eukaryotic phospholipid synthesis, Fatty acid elongation, and Phospholipid signaling. The level of phosphatidic acid (PA) increased drastically in response to cold stress, indicating the importance of phospholipase and phosphatase genes in membrane lipid turnover.
