Summary: Rice, as a staple food crop, is crucial for global food security, but soil salinity hampers its productivity. In this study, 160 RILs were evaluated for salt tolerance at the seedling stage, leading to the identification of nine QTLs associated with salt tolerance. The analysis of coding sequence variants and gene expression under salt stress highlighted 47 candidate genes, including Os01g0200700 and Os12g0625000, which could potentially improve rice productivity and resistance under salt stress conditions during the critical seedling stage.

Summary: This study isolated Se-tolerant plant-growth-promoting bacteria (PGPB) from soils collected from a Se tailing. The strain LWS1 belonging to Priestia sp. showed good growth in M9 medium and exhibited typical PGP characteristics. It also demonstrated tolerance to selenite (SeIV) and enhanced biomass and Se concentration in rice. These findings suggest that microbial Se biofortification through inoculating with strain LWS1 can improve Se uptake in crops.

Summary: This study discusses the role of salinity responsive metabolites in rice and its wild species. Salinity stress severely affects rice productivity, and while many important physiological and molecular responses have been studied, the role of salt stress and microbes-induced metabolites in overcoming salt stress in rice has been less explored. Metabolomic studies have allowed for a comprehensive analysis of rice salt stress responses. This review discusses the alterations in various metabolites triggered by salt stress in rice and their significant roles in salinity tolerance, including as signaling molecules and protective agents. The accumulation of metabolites induced by salinity stress varies between salt-sensitive and tolerant rice genotypes, contributing to their different degrees of salt tolerance. Additionally, certain tolerance metabolites may induce unique pathways for defense mechanisms in salt-tolerant rice varieties, suggesting their potential roles as universal biomarkers for salt tolerance. The review also explores the involvement of rhizosphere microbes in rice salt tolerance. Overall, this study provides valuable insights into salt-induced metabolites in different rice genotypes and their relationships with stress genes, offering a reference point for biomarker design in rice. It also helps to decipher metabolic systems associated with salt tolerance in rice, which can be useful for developing salt-tolerant rice cultivars through conventional breeding, genetic engineering, or exogenous application of metabolites.

Summary: This research conducted a sampling survey of heavy metals contents in selenium-rich rice, which revealed the association between selenium and cadmium accumulation in rice and soil. A pot experiment confirmed the significant association between the contents of selenium and cadmium in rice grain and the concentrations of selenium and heavy metals in soil. Transcriptome analysis indicated the up-regulation of transporter-coding genes may promote the absorption of selenium and cadmium. The up-regulation of antioxidant-coding genes and cadmium chelator transporter coding-genes was observed to reduce the toxicity of cadmium. Moreover, the up-regulation of key genes of the ascorbic acid-glutathione metabolic pathway were responsible for the association between selenium and cadmium in Se-rich rice.

Summary: This study reveals the molecular basis of melatonin-mediated salt tolerance in rice by integrated transcriptome and metabolome profiling. Exogenous melatonin enhances salt tolerance by activating multiple antioxidant pathways, including the AP2/EREBP-HB-WRKY transcriptional cascade and phytohormone signaling pathways. Metabolome analysis identifies specific metabolites with antioxidant functions that contribute to melatonin-mediated salt tolerance.

Summary: This study investigates the growth and morpho-physiological responses of the MR219 rice variety to salinity stress during the early vegetative stages. The results show that low salinity improves seed germination, while higher salinity inhibits germination. Salinity also leads to significant reductions in photosynthesis rate, transpiration rate, stomatal conductance, and leaf chlorophyll content, affecting plant growth.

Summary: The effects of biochar amended fishpond sediments on soil properties and plant physiological and biochemical changes were investigated. It was found that the addition of biochar-treated sediments increased nutrient content and reduced chromium levels in soil, resulting in improved plant growth and photosynthesis. The treatment also increased antioxidant enzymes and soluble sugars content, while decreasing proline content, Malondialdehyde, hydrogen peroxide, and chromium concentration in spinach tissues. Moreover, the biochar-treated sediments effectively reduced the human health risks associated with chromium consumption.

Summary: The conversion of organic matter and phosphorus during the composting process of vegetable waste is influenced by the addition of microbial inoculants. This study investigated the effects of straw-decomposing microbial inoculant (SDMI) on the stability of organic matter and activation of phosphorus in the composting of vegetable waste. The addition of SDMI promoted the degradation of dissolved organic carbon, improved phosphorus stability, and enhanced the thermal stability of organic matter. The results showed that stable forms of phosphorus, such as aluminum phosphate and iron-containing phosphate, were the main forms of phosphorus in the final compost. These findings provide a basis for producing high-quality vegetable compost products and improving the reutilization potential of vegetable waste.

The results showed that SAPs improved the seedling germination index, especially at 0.5% concentration. However, the final germination percentages were not significantly different for both seeds. Therefore, SAPs could be a promising solution for increasing moisture conservation in a sandy soil for seed germination.

Summary: Nitrogen is crucial for plant growth and productivity, but excessive and ineffective use of nitrogen fertilizer leads to higher production costs and environmental pollution. To promote sustainable food production and protect the environment, there is growing interest in reducing nitrogen fertilization and improving plant tolerance to nitrogen deficiency. Dopamine, an antioxidant, plays a role in various physiological and biochemical processes in plants. However, its impact on crisphead lettuce's tolerance to nitrogen deficiency has not been well-documented.
