Summary: The NAC gene family plays important roles in regulating plant growth, development, and stress response. CpNAC1 is a key gene in wintersweet, expressed in various tissues and induced by abiotic stresses and ABA treatment. Overexpression of CpNAC1 reduces osmosis tolerance in transgenic Arabidopsis, suggesting its involvement in negatively regulating drought stress response.

Summary: The study identified an orthologous gene of the DWARF AND DELAYED FLOWERING (DDF) members in Arabidopsis, SlDDF2, in tomato plants and observed its clear induction in response to ABA treatment, cold, salinity, and drought stresses. Transgenic lines with stress-inducible overexpression of SlDDF2 showed growth retardation phenotypes and higher chlorophyll content under stress conditions. Compared to wild-type plants, the transgenic lines exhibited enhanced tolerance to different abiotic stresses including water deficit, salinity, and cold.

Summary: Plants face a more volatile environment due to their immobility, prompting the development of efficient mechanisms to adapt to stress. MYB transcription factors, a widespread family in plants, play critical roles in plant development and responses to stresses. Multiple studies have shown that MYB proteins are involved in diverse roles in responses to abiotic stresses, but their regulatory mechanism is still not well understood.

Summary: This study identified and analyzed the WRKY gene family in black raspberry and classified them into three groups through phylogenetic analysis. The conserved motif analysis revealed three core conserved domains in this gene family. Gene expression analysis showed that 12 WRKY genes were highly expressed in black fruits and leaves. Furthermore, the expression difference at different treatment times indicated that the response of most WRKY transcription factors to NaCl and ABA treatment in black raspberry is temporal.

Summary: Heavy metal contamination in soil and water is a global issue, posing health risks to plants, animals, and humans. Plants have evolved mechanisms to cope with heavy metal toxicity, including vacuolar sequestration. Manipulation of genes involved in vacuolar sequestration pathways has led to the development of transgenic plants for phytoremediation and food safety applications.

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: This study identified the high nitrogen use efficiency (NUE) black sesame variety 17-156 and analyzed its underlying physiological and molecular mechanisms. The results showed that 17-156 possesses a sophisticated nitrogen metabolizing machinery to uptake and assimilate higher quantities of inorganic nitrogen, simultaneously improving carbon metabolism and growth. Many important genes were up-regulated in 17-156 under high nitrogen condition. Additionally, 38 potential candidate genes were identified for future studies to improve sesame's NUE. These findings provide valuable resources for understanding the regulatory network of nitrogen metabolism and developing sesame cultivars with improved NUE.

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.
