Summary: This study evaluated the physicochemical properties and texture of heat-moisture modified black and red rice starch. The results showed that heat-moisture treatment altered the granule structure of the starch and affected its color and phenolic compounds. The modification improved the absorption capacity of water, oil, and milk, reduced syneresis, and increased stability during storage.

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.

Summary: Exhaustive searches of the rice genome revealed 30 potential OsDof genes, with analyses conducted on their subcellular localization, phylogenetic relationship, conserved motifs, chromosomal allocation, expression patterns, and interaction networks. The Dof proteins in rice were found to be distributed into 4 groups, showing significant variances in expression levels across tissues and developmental stages. Protein-protein correlation network analysis indicated potential overlapping functions and co-expression among some OsDofs, providing insights for further studies and development of high-quality rice varieties.

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: In this study, a population of chromosome segment substitution lines (CSSLs) derived from a cross between two different types of rice was used to analyze multiple traits of brown rice. The results showed significant correlations among most of the brown rice traits and identified 61 QTLs for these traits under three environments. Additionally, 30 pairs of gene interactions were determined for specific brown rice traits, providing further understanding of the genetic basis of brown rice traits and facilitating genetic improvement of rice yield and quality through breeding.

Summary: This research discovered the formation of neocentromeres in rice, which are assembled at DNA loci not previously associated with CenH3 nucleosomes. Neocentromeres can rescue rearranged chromosomes that have lost a functional centromere and avoid chromosomal regions containing functional genes. It was also found that canonical histone H3 was replaced by CENH3 in regions with low CENH3 levels.

Summary: The study revealed that the activity concentrations of natural radionuclides in rice and soil samples in the Mekong Delta region of Vietnam remained relatively stable. It was found that the irrigation system was the main factor causing the accumulation of radionuclides in the soil, and the accumulation rates of radionuclides can be controlled by changing cultivation conditions.

Summary: A candidate gene responsible for higher grain zinc accumulation in rice was identified, potentially linked to a partial defect in anther dehiscence. The study highlighted the importance of balancing fertility and grain zinc levels as essential agronomic traits in rice. The results suggest that regulating the expression of specific genes involved in anther dehiscence could impact grain productivity and zinc accumulation in rice plants carrying the identified chromosomal segment.

Summary: This study analyzed the core microbiome associated with scented and non-scented rice rhizosphere, revealing significant differences in composition and diversity. The analysis also identified distinct and unique microbiota in the rhizosphere of scented rice varieties. Functional gene annotation showed a high abundance of genes related to the biosynthesis of aroma compounds in scented rice. The findings suggest that the specific rhizobacteria identified in this study could be used as bioinoculants to enhance aroma, yield, and sustainable cultivation of rice.

Summary: The study evaluated the effectiveness of foliar spray of silica in alleviating water stress in rice. It was found that foliar application of silica improved the drought tolerance of rice by enhancing plant growth and physiological parameters. The integration of silica in breeding programs is recommended to develop drought-tolerant rice cultivars.

Summary: Global rice crop production is threatened by increasing temperatures and drought, which negatively affect rice's characteristics and productivity. Physiological changes, such as stomata closure and reduced photosynthesis, occur under heat and drought stress, leading to decreased crop yield. These stresses also cause metabolic changes, including increased enzyme activities and reactive stress metabolites. The reproductive stage of rice is particularly sensitive to high temperature and drought, resulting in low seed setting and grain yield. Genetic improvement and development of stress-tolerant rice varieties are the best approaches to enhance yield even under stress conditions. This article summarizes the effects of heat and drought stresses on rice's physiological traits and explores different approaches for managing these stresses.

Summary: SUB1A, an ethylene-responsive transcription factor gene, plays a role in regulating the restricted elongation of uppermost leaves in response to submergence in rice. This study investigates the molecular and physiological functions of SUB1A in mature and growing leaves under submergence. The results show that SUB1A modulates different sets of hormonal pathways, contributing to distinct adaptive responses in mature and growing rice leaves.

Summary: The lodging variation among different Chinese weedy rice strains and between weedy rice and cultivated rice was compared in this study. The results showed that indica-derived weedy rice strains had higher lodging levels in southern China, while japonica-derived strains had lower lodging levels in the north. The more lodging-prone indica weedy rice had lower bending stress and lignin content, and a lower cellulose to lignin ratio compared to co-occurring cultivated rice. DNA methylation of lignin synthesis-related genes affected the expression levels and the cellulose to lignin ratio, thus regulating lodging variation in weedy rice.
