Summary: In the face of climate change, water stress poses a serious threat to crop growth and yields. The development of water stress-tolerant plants and understanding the mechanisms behind their tolerance are crucial. This study investigates the response of NIBER & REG; (a proven water stress-tolerant pepper hybrid rootstock) and A10 (a sensitive pepper accession) to short-term water stress, uncovering differences in gene expression and metabolite content. The findings highlight the strategies employed by NIBER & REG; to overcome water stress, including the upregulation of transcription factors, increased levels of certain hormones and antioxidants, and enhanced gene expression for water channel proteins and molecular chaperones.

Summary: The application of chitosan nanoparticles (CSNPs) can enhance the symbiosis between arbuscular mycorrhizae fungi (AMF) and wheat, leading to improved growth, physiology, and metabolism in the plant. CSNPs treatment increased AMF colonization, auxin and strigolactone levels, and flavonoid exudation in the roots. This, in turn, resulted in higher plant biomass production, photosynthetic rate, and accumulation of health promoting compounds.

Summary: This study investigated the effects of europium (Eu) on the growth, photosynthesis, and redox homeostasis in barley, and how these effects can be influenced by future CO2 climate. The results showed that soil application of Eu led to its accumulation in plant shoots and significantly reduced biomass and photosynthesis-related parameters. Additionally, Eu induced oxidative stress and lowered ASC/DHA and GSH/GSSG ratios. Interestingly, elevated CO2 levels mitigated the adverse effects of Eu by supporting antioxidant defense mechanisms and enhancing metal detoxification capacity.

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.
