Summary: The study revealed that polystyrene nanoparticles (PS-NPs) were taken up by rice roots, leading to oxidative stress response in the roots and affecting root length and lateral root numbers. Additionally, PS-NPs treatment activated carbon metabolism in rice roots while inhibiting jasmonic acid and lignin biosynthesis.

Summary: Flooding caused by heavy rainfall and poor soil drainage can negatively affect plant germination and seedling establishment. Rice, however, has unique strategies, such as fast elongation of coleoptiles, to cope with flooding. Microorganisms can contribute to rice health by promoting growth and protecting against stress. A metagenomic analysis of the microbiome during rice germination under submergence revealed distinct compositions of microbiota in different rice varieties, with Arborio seeds showing the development of long coleoptiles. The isolated bacteria were found to have starch hydrolyzing and indole-related compound production abilities under hypoxia. Inoculating these bacteria into submerged rice seeds showed a genotype-dependent response. These findings highlight the importance of endophytic bacteria in promoting rice seedling establishment during flooding.

Summary: In this study, the longitudinal pattern of rice root aerenchyma formation was investigated using four non-linear models, with the Ti-Gompertz model found to be the best fit. Critical points of Ti-Gompertz were calculated to determine the rapid stage of aerenchyma formation within a distance range of 1.38-4.19 cm from the root apex.

Summary: The interaction between natural nanocolloids (Ncs) in soil and cadmium (Cd) was investigated. Cd was found to bind to soil Ncs surface through hydrophilic effects and pi - pi interactions. Coexposure of soil Ncs and Cd significantly affected the phytotoxicity of Cd to rice roots, and downregulated metabolic pathways contributed to this adverse effect.

Summary: This study identified OsNAC300 as a key transcription factor in regulating plant responses and tolerance to cadmium stress in rice. OsNAC300 was found to modulate the expression of multiple genes involved in Cd stress responses and directly bind to their promoters to activate transcription. The findings suggest that OsNAC300 plays a crucial role in mediating Cd stress responses and tolerance mechanisms in rice.

Summary: EXO70 is a key factor in vesicle transport and plays crucial roles in various cellular processes in eukaryotes. The study of SR1, a gene with an EXO70 domain in plants, has revealed its importance in regulating root development through effects on cell proliferation and tracheary element formation. SR1 mutation impacts root growth and membrane transport, providing insights into the molecular mechanisms underlying plant root development in Oryza sativa (rice).

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: This study investigated the impact of sulfur on the chromium tolerance of rice plants and found that a moderate sulfur treatment can effectively reduce the bioavailability of chromium in rice shoots. The barrier capacity of iron plaque to chromium absorption in rice plants was found to be primarily influenced by the applied chromium concentration and the competition between chromium and sulfur at the absorbing sites.

Summary: This study used a genome-wide association analysis to identify marker trait associations related to adaptive traits in barley under waterlogged conditions. Adventitious roots and root cortical aerenchyma formation were key adaptive traits for waterlogging tolerance. Combinations of different marker trait associations were found to enhance barley's tolerance to waterlogging stress.

Summary: The application of exogenous silicon in different ways can significantly increase the retention capacity of rice root for Cd, reduce Cd concentrations in root compartments, and enhance Cd sequestration in roots. TJ-Si is more effective in increasing Cd retention and decreasing Cd migration in rice roots compared to T-Si and J-Si.

Summary: Co-contamination of soil by microplastics (MP) and arsenic (As) poses a severe threat to agricultural productivity. The impact of this joint pollution on crop growth was assessed by investigating the transcriptomic and phenotypic patterns of rice. The results showed that MP had less impact on rice growth compared to As, but the MP-As mixture decreased rice's aboveground biomass and altered the distribution of As in rice tissues. Transcriptomic analysis revealed that the joint application of MP and As produced a synergistic effect on crucial metabolic processes and reprogrammed the expression of hub genes involved in photosynthesis and defense. These findings suggest that MP aggravates the As-induced toxicity in rice plants and may affect the crop's adaptation to other abiotic field environments.

Summary: This study investigated the effects of different doses of polystyrene (PS) and polyvinyl chloride (PVC) microplastics (MPs) on the growth, ionic homeostasis, and antioxidant metabolism of rice plants. Results showed that PVC-MPs accumulation had a more devastating impact on rice growth and metabolism compared to PS-MPs, with D-3 and D-6 being the most harmful treatments. Further research is recommended to fully understand the influence of different sized MPs on food safety.
