Summary: This study found that 50% shading treatment can increase the growth height of Aralia elata and reduce the activity of antioxidant enzymes and relative conductivity. It also increases chlorophyll content and improves the maximum quantum efficiency of photosystem II, quantum efficiency of electron transfer, and photochemical quenching. Meanwhile, antioxidant enzyme activity, chlorophyll content, maximum quantum efficiency, quantum efficiency of electron transfer, photochemical quenching, and non-photochemical quenching are all higher in top leaves compared to central and bottom leaves.

Summary: This study investigated the expression of defence traits in the spiny plant Aralia elata under different light and nutrient conditions. The results showed that spine mass, spine mass fraction, total phenols and condensed tannins all increased with canopy openness, while total phenol content was negatively related to soil nitrogen. In low light conditions, spiny genotype trees had lower spine mass fraction and total phenols, and nutrient additions had negative effects on spine mass fraction and total phenols.

Summary: MeJA treatment promoted the accumulation of squalene and OA in transgenic A. elata, with a significant increase in gene expression levels. The maximum content of both products reached 17.34 and 0.70 mg/g after three days of MeJA treatment, showing a significant enhancement compared to the untreated lines. These results suggest that MeJA can activate the biosynthesis pathways of squalene and OA, leading to an increase in yield.

Summary: Cytokinins are a class of phytohormones that regulate plant growth, development, and stress responses by interacting with transcription factors through a series of phosphorylation cascades. They also play a crucial role in crosstalk with other phytohormones to modulate plant development and stress reactions. This review provides a comprehensive overview of cytokinins as central regulators of plant biology and highlights areas for future research.

Summary: This study explored the effects of shading stress on the growth of two mung bean cultivars. The results showed that shading stress significantly weakened the leaf photosynthetic capacity and led to morphological and physiological changes in the plants. Yulv 1 exhibited stronger tolerance and ecological adaptability to shading stress compared to Xilv 1, which was related to changes in chlorophyll content and hormone concentrations.

Summary: The Salt Overly Sensitive (SOS) pathway is crucial for plant salinity tolerance. Proteins that positively or negatively regulate the core components of the SOS pathway at the protein and transcript levels have been identified. This review summarizes recent advances in the functional regulation of the SOS pathway and its upstream effectors in plants, highlighting their roles in plant development and stress adaptation through modulation of the SOS core proteins at the transcriptional and post-translational levels.

Summary: Plant sterols are important in cell membrane and lipid rafts, playing key roles in plant development and stress resistance. Recent studies have focused on the biosynthesis pathway of plant sterols, but the regulation and accumulation of sterols are not well understood. This review summarizes and discusses the latest findings in plant sterols, including their biosynthesis, regulation, functions, and involvement in abiotic stress responses.

Summary: OsNAC016, a rice transcription factor, regulates plant architecture and drought tolerance in rice by mediating the crosslink between brassinosteroid and abscisic acid signaling. It regulates gene expression, protein phosphorylation, and degradation, and is modulated by GSK2, SAPK8, and OsPUB43. This study provides insights into how rice balances growth and survival under abiotic stresses.

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.
