Summary: Through the study of the cat2 mutant in Arabidopsis, which lacks the major leaf isoform of catalase, we are able to investigate the potential impact of intracellular H2O2 on plant function. Our analysis focused on the salicylic acid and jasmonic acid pathways reveals metabolic signatures associated with oxidative stress-induced signaling via these defense hormones. We also identify specific enzymes and genes involved in the glucosylation of SA and the production of dihydroxybenzoic acid glycosides.

Summary: The study revealed that LuFAD2A and LuFAD3A from the 'Longya 10' cultivar of L. usitatissimum play predominant roles in the biosynthesis of linoleic acid and linolenic acid, respectively, leading to a significant increase in fatty acid contents in Arabidopsis thaliana seeds when overexpressed. Additionally, LuFAD2A and LuFAD3A promote the biosynthesis of jasmonic acid by increasing the levels of linolenic acid, enhancing plant cold tolerance.

Summary: Drought priming increases drought tolerance in wheat by up-regulating genes related to ABA and JA signaling pathways. The interplay between ABA and JA is essential for priming-induced drought tolerance, with JA acting upstream of ABA. Inhibitors of ABA and JA biosynthesis affect plant responses to drought stress under priming conditions.

Summary: Jasmonic acid (JA) can reduce the content of cadmium (Cd) in rice roots and shoots by promoting the combination of Cd on soluble pectin and inhibiting Cd movement into protoplasts. Additionally, JA application can help alleviate lipid peroxidation damage induced by Cd by reducing H2O2 content. Field experiments also showed that foliar spraying of JA can inhibit the transport of Cd from the stalk and root to the grain in rice.

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.
