Summary: In this study, a new salt-induced ASR gene (OsASR6) in rice was identified and functionally characterized. Overexpression of OsASR6 enhanced salt and oxidative stress tolerance in rice plants by reducing H2O2, malondialdehyde (MDA), Na/K, and relative electrolyte leakage. Additionally, OsASR6 was found to interact with OsNCED1, a key enzyme in ABA biosynthesis.

Summary: This study finds that the inter-subspecific hybrid rice ZGY1578 shows higher seedling survival after salt treatment compared to its parents ZH1578 and ZG7A. RNA sequencing reveals that there are 2584 and 3061 differentially expressed genes between ZGY1578 and ZG7A, and ZGY1578 and ZH1578, respectively, in the roots under salt stress. The expressions of transcription factors, hormones, and ROS-related genes in the hybrid are lower or higher compared to its parents, suggesting their involvement in the heterosis of salt tolerance.

Summary: This study found that plant growth-promoting endophytic actinomycetes can enhance plant growth and mitigate abiotic stresses. The PGPE Streptomyces sp. GKU 895 promoted growth and alleviated salt tolerance in rice by regulating gene expression involved in growth, development, photosynthesis, hormones, ROS scavenging, ion transport, and plant-microbe interactions. This research suggests that utilizing beneficial endophytes can improve the growth of rice and other crops in saline fields.

Summary: This study identified a novel gene, OsSKL2, in rice that plays an important regulatory role in salt and drought tolerance. Overexpression of OsSKL2 increased the plant's ability to tolerate salinity, drought, and oxidative stress, while its suppression enhanced sensitivity to stress treatments. Additionally, OsSKL2 was found to interact with another protein, OsASR1, which also contributes to salt and drought tolerance.

Summary: Catalase (CAT) is an antioxidant enzyme whose function is regulated by phosphorylation. In this study, we investigated the functions of five phosphorylated serines (Ser-9, -10, -11, -18, and -205) in CatC in rice. We found that phosphorylated Ser-9 and -11, as well as dephosphorylated Ser-18, promoted the enzymatic activity of CatC and increased oxidative and salt tolerance in yeast. Dephosphorylated Ser-18 also enhanced CatC tetramerization to enhance its activity.

Summary: In this study, a salt stress-responsive gene, OsJRL45, was identified in a salt-tolerant rice variety. OsJRL45 positively regulated the salt tolerance of rice plants at all growth stages and increased the yield of a salt-sensitive rice cultivar under salt treatment. It enhanced the antioxidant capacity of rice plants and regulated Na+/K+ dynamic equilibrium under salinity conditions. The findings suggest the importance of OsJRL45 in improving salt tolerance in rice.

Summary: Soil salinization-induced crop yield loss is a growing threat to global agriculture. The growth, development, and grain productivity of rice are significantly affected by salt stress, and enhancing rice tolerance to salt stress is crucial for meeting the increasing food demand. The main contributors to salt toxicity on a global scale are Na+ and Cl- ions, which affect up to 50% of irrigated soils. Plant responses to salt stress occur at various levels and involve maintaining ion balance, osmotic adjustment, scavenging reactive oxygen species (ROS), and maintaining nutritional balance. This review summarizes recent research progress on these four aspects of plant physiological response, with a focus on hormonal and gene expression regulation, as well as salt tolerance signaling pathways in rice. The information presented here will be valuable for accelerating the breeding of salt-tolerant rice.

Summary: The study found that the effect of FPB on rice plants varies with planting time, growth stage, and rice cultivar. P450 inhibitors can reduce the doses of FPB needed to cause plant injury and growth reduction without compromising crop selectivity. FPB also impacts the expression of specific enzymes in rice plants, emphasizing the need for further research on its bio-activation mechanism.

Summary: Research has shown that the rice gene OsCCR10 is directly activated by the transcription factor OsNAC5, mediating drought tolerance through lignin accumulation. Overexpression of OsCCR10 in transgenic rice plants results in improved drought tolerance and higher lignin content, while knockout mutants exhibit reduced lignin accumulation and drought tolerance. Transgenic rice plants with root-preferential overexpression of OsCCR10 also show higher grain yield under field drought conditions, indicating the importance of lignin biosynthesis in drought tolerance.

Summary: Wood vinegar is commonly used in agriculture as organic fertilizer and antibacterial agent. This research study shows that pretreatment of wood vinegar can alleviate the inhibitory effects of salt stress on rapeseed cultivation by promoting plant growth, improving photosynthetic efficiency, and maintaining redox balance. The protective mechanism of wood vinegar involves reducing oxidative stress, lipid peroxidation, and improving antioxidant enzyme activities. Furthermore, wood vinegar also regulates the expression of salt transporter genes and reduces the uptake of Na+ in plants under salt stress. This study provides valuable insights into the interaction between wood vinegar and ion homeostasis in plants under salinity stress.
