Summary: The AP2 and ERF gene family plays a critical role in plant development, stress response, and evolution. HcTOE3, a cold-regulated transcription factor gene, positively regulates freezing stress and has the potential to improve plant freezing tolerance. Overexpressing HcTOE3 enhances freezing tolerance in transgenic plants by up-regulating the expression of cold responsive genes and abscisic acid signal transduction pathway genes.

Summary: Salt and drought are major abiotic stresses affecting plant growth and crop yields. Understanding the molecular mechanisms of stress tolerance in certain plants can help in breeding new cultivars for agriculture. This study focuses on the miR169b/NFYA1 module from Halostachys caspica and its involvement in abiotic stress tolerance. The results suggest that the module enhances salt and drought tolerance in plants by promoting ABA synthesis and signal transduction pathways, as well as maintaining ROS homeostasis and cell membrane stability.

Summary: The study revealed that new genes in rice have relatively low expression levels, possibly controlled by distal enhancers and chromatin conformation at their TSS; the chromatin in TSS regions may be remodeled in response to abiotic stress, indicating conditional expression of young genes. Furthermore, transcripts of young genes in Arabidopsis are prone to nonsense-mediated RNA decay, restricting their expression.

Summary: Global climate change has increased drought frequency and severity, potentially affecting coniferous terpene biosynthesis, but the regulatory mechanism remains unclear. This study investigated the mechanism of terpenoid regulation under drought stress in slash pine, analyzing changes in terpenoid composition and gene expression. The results identified differentially expressed genes (DEGs), including transcription factors associated with plant resistance, proteins involved in terpene synthesis, and a potential regulatory role of a specific gene (PITA_24906) in levopimaric acid production. These findings enhance our understanding of slash pine defense mechanisms and provide a foundation for its management and genetic improvement.

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: High temperature is a critical factor affecting rice growth, development, and yield. This study evaluated the heat tolerances of two rice varieties and found differences in their response to heat stress. Analysis of H2O2 and proline content revealed different oxidative and stress responses in the two varieties. Transcriptome analysis identified several pathways involved in heat response, with protein processing in the endoplasmic reticulum playing a key role. Additionally, 22 key genes were identified through protein-protein interaction analysis. This study enhances our understanding of thermotolerance mechanisms in rice and provides a foundation for breeding thermotolerant cultivars through molecular breeding.

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: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

Summary: Selenium (Se) can reduce uptake and translocation of cadmium (Cd) in plants by regulating root morphology. This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.
