Summary: Plants accumulate triacylglycerol in vegetative tissues under stress conditions by activating key transcription factors regulating seed triacylglycerol biosynthesis to enhance plant tolerance to environmental stresses. This metabolic reprogramming is driven by transcriptional regulation, involving both seed maturation program derepression and stress-induced transcription factors activation, linking TAG biosynthesis with plant survival in adverse environments.

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.

Summary: In this study, a temperature-induced lipocalin-1-like gene (DgTIL1) was identified from chrysanthemum, which showed notable induction in response to cold stress and enhanced cold tolerance in transgenic chrysanthemum. The interaction between DgTIL1 and DgnsLTP was found to promote POD gene expression and activity, reducing ROS accumulation and improving cold resistance in DgnsLTP transgenic chrysanthemum. Lysine crotonylation of DgTIL1 prevented DgnsLTP degradation, enhancing POD expression and activity, ultimately promoting cold resistance in chrysanthemum.

Summary: This study investigates the temporal cis-regulatory basis of switchgrass transcriptional response to cold by analyzing the switchgrass transcriptome dataset. Machine learning models and enrichment analysis reveal putative cis-regulatory elements (pCREs) that are likely important for cold response in switchgrass, including novel sequences previously not known. These findings contribute to a better understanding of the molecular mechanisms underlying cold response in switchgrass.

Summary: Salisbury et al. demonstrate that m(6)A modifications play a sex-dependent and dietary-dependent role in regulating hepatic lipid metabolism, triaging lipogenic transcripts for degradation and preventing hepatic triglyceride accumulation. The loss of m(6)A control in male livers under lipid-rich conditions leads to a more 'feminized' hepatic lipid composition, which can be significantly diminished by liver-specific deletion of the m(6)A complex protein Mettl14 in both male and female mice. Additionally, the m(6)A installing machinery is subject to transcriptional control by the sex-responsive BCL6-STAT5 axis in response to dietary conditions, providing insights into the molecular basis for sex-specific differences in hepatic lipid traits.

Summary: This study used RNA sequencing to investigate the gene expression differences between two cold tolerant and sensitive chickpea genotypes. The results showed that the sensitive genotype had significant down-regulation of genes related to photosynthesis under cold stress, while the tolerant genotype exhibited several protective and signaling genes. These findings are important for improving cold tolerance in chickpea through molecular breeding or genetic engineering.

Summary: In this study, the protein regulation mechanism of low-temperature tolerance in Haemaphysalis longicornis was investigated. The results showed that maintaining cell homeostasis, cell viability, and enhancing cell tolerance were crucial for the ticks to survive under low temperatures. Furthermore, arylamine N-acetyltransferase, inositol polyphosphate multikinase, and dual-specificity phosphatase were identified as potential key proteins in low-temperature tolerance.

Summary: This study evaluated the cold tolerance of a new variant, Chuannong-3, under field conditions and investigated the metabolic and molecular mechanisms underlying its cold tolerance compared to triploid Tifdwarf and tetraploid common bermudagrass 001. Chuannong-3 exhibited the highest tolerance to low temperature, with lower oxidative damage, chlorophyll loss, and inhibition of photochemical efficiency, as well as higher water-soluble carbohydrate content. It also showed higher levels of glucose, fructose, sucrose, and raffinose, and greater expression of raffinose synthase and CdSPS1, providing potential protection against chilling and freezing damage. The Chuannong-3 had enhanced ABA-dependent and ABA-independent pathways, indicating its better ability to acclimate to low temperature stress. This new variant could be valuable for turfgrass cultivation in temperate and transition zones.

Summary: In this study, pot experiments were conducted to investigate the differences in salt tolerance indices among six Salix matsudana clones under various concentrations of NaCl stress. Salt-tolerant clones and key salt tolerance indices were identified. Transcriptome sequencing analysis revealed the relationship between physiological indices and gene expression. Superoxide dismutase, peroxidase, chlorophyll, and net photosynthetic rate were found to be closely related to salt tolerance in Salix matsudana. Differentially expressed genes and transcription factors were also identified as potential genetic resources for salt tolerance breeding.

Summary: Tropospheric ozone has significant effects on the remobilization and allocation efficiency of aboveground biomass and nutrients in cereal crops. Long-term ozone exposure increases straw C:N ratio and affects grain C:N ratio. Grain N concentrations increase significantly under ozone stress, but N yield declines due to grain yield losses. Various indicators of N use efficiency are reduced, indicating reduced N absorption from soil and allocation from vegetative to reproductive organs. Straw C:N ratio is not suitable for predicting wheat productivity. Nitrogen harvest index (NHI) is not affected by ozone stress, but the relationship between harvest index (HI) and NHI is changed by elevated ozone concentration.

Summary: This study aimed to investigate the physiological response of broccoli leaves to abiotic stresses such as salinity and boron toxicity/deficiency. The results showed that the combined stress of salinity and boron deficiency resulted in a significant reduction in plant biomass, and the adaptation mechanisms were associated with water and boron concentration in the leaves. The expression patterns of PIP aquaporins varied among the different stress treatments, and their presence in the plasma membrane and interaction with the lipid environment played potential regulatory roles in facilitating salinity-boron stress adaptation mechanisms.

Summary: Plants activate a sophisticated signaling cascade in response to pests and pathogens, with lipids playing a crucial role in mediating these defense responses. Different types of lipids are involved in cell signaling during plant-pathogen interaction and each lipid has specific relevance and contributes to specific signaling cascades. Lipid biosynthetic enzymes, including phospholipases, are involved in the production of defense signaling molecules. Lipids participate in stress signaling by mediating signal transduction, acting as precursors for bioactive molecules, regulating ROS formation, and interacting with phytohormones.
