Summary: In this study, the effects of OsCIPK17 gene on agronomic traits, photosynthetic parameters, transcriptome, and gene expression were analyzed using mutant cipk17 and Nipponbare in field experiments. The results showed that OsCIPK17 was expressed in multiple organs and involved in root, stem, and leaf growth. Knockout of OsCIPK17 resulted in a decrease in grain filling rate and final grain weight, as well as reduced efficiency of Photosystem II. Enrichment analysis and fluorescence analysis further confirmed the functions of OsCIPK17 in photosynthesis and metabolism-related gene expression.

Summary: The demand for improved rice grain quality is a pressing concern, but limited gene resources and inefficient breeding methods have hindered progress. In this study, researchers used the CRISPR/Cas9 system to edit the gene OsAAP11, which is involved in amino acid transport in rice endosperm. They successfully obtained mutant plants with enhanced eating and cooking quality without transgenic insertion. This study provides valuable genetic resources and technical support for improving rice grain quality.

Summary: The study reveals that OsGW2 acts as a negative regulator of grain size in indica rice by affecting both cell number and cell size in the spikelet hull. This is achieved through downregulation of OsGW2 by RNAi technology, resulting in wider and heavier grains. Transcriptome analysis identified upregulated genes related to grain size regulation in an OsGW2_RNAi transgenic line among 1,426 differentially expressed genes.

Summary: OsMADS1 is found to play a critical role in regulating rice grain quality. Through the study of the "Oat-like rice" mutant, it is discovered that the mutated OsMADS1 gene leads to decreased grain quality, including chalky endosperms, abnormal morphology, and loose arrangement of starch granules, as well as lower starch content but higher protein content in grains. Further transcriptomic analysis reveals that OsMADS1 regulates the gene expressions and regulatory networks of starch and storage protein metabolisms, thus influencing rice grain quality. This research not only uncovers the important function and initial mechanism of OsMADS1 in regulating rice grain quality but also highlights the potential application of OsMADS1 and the target gene seed-specific RNAi system in improving rice grain quality through molecular breeding.

Summary: Grain size plays a crucial role in determining both grain weight and quality. In this study, a new quantitative trait locus (QTL) called GLW7.1 (Grain Length, Width and Weight 7.1) was identified, which encodes a CCT motif family protein called GHD7. GLW7.1 was found to promote the transcription of cell division and expansion genes, leading to larger cell size and increased cell number, resulting in enhanced grain size and weight. GLW7.1 was also shown to increase endogenous GA content by up-regulating the expression of GA biosynthesis genes. Furthermore, GLW7.1 was found to interact with several grain-size-related proteins and the rice DELLA protein SLR1. The presence of GLW7.1 in rice lines was also associated with reduced chalkiness and improved cooking and eating quality.

Summary: Drought stress is a significant threat to rice productivity. This study analyzed the genetic variations between drought-tolerant and drought-sensitive rice cultivars and identified millions of single nucleotide polymorphisms and insertions/deletions. The genetic variations were unevenly distributed throughout the rice genome, with a higher frequency near the transcription start and stop sites. The study also identified cis-regulatory motifs and differentially expressed genes associated with stress-related transcription factors, providing valuable insights into candidate genes for drought stress tolerance in rice.

Summary: Ultrasonication generates acoustic cavitation in an aqueous medium, affecting starch chemistry and rice grain characteristics. It introduces fissures and cracks, facilitating water uptake and altering starch characteristics, ultimately enhancing palatability and stimulating the production of health-related metabolites.

Summary: MicroRNAs (miRNAs) play important roles in regulating various plant processes by blocking the expression of target genes. In this study, the functional conservation and divergence of miR156 and miR529 were explored in rice. It was found that miR156 and miR529 respectively function dominantly in the vegetative stage and reproductive stage to control rice growth and development by regulating the accumulation of OsSPL14.

Summary: The effect of Se-nanoparticles (SeNPs) fertilizer on rice quality was investigated. The results showed that Se treatments significantly increased the content of Se in brown and polished rice. Cd content increased while As and Cr content decreased in rice grains after Se treatments. SeNPs had no significant impact on rice eating and cooking quality, but could slightly improve the fatty acid content. In general, the use of SeNPs fertilizer at a rate of 6.4 g/ha was identified as the optimal choice for improving grain Se content and quality.

Summary: This study aimed to evaluate the effects of drying-tempering time and air temperature on the quality of polished rice. The results showed that the increase in temperature and prolonged drying-tempering time adversely affected the physical, physicochemical, and morphological qualities of the rice. It was concluded that drying technologies with tempering periods should be designed with a maximum temperature of 75 degrees Celsius and drying time not exceeding 8 hours for optimal rice quality.

Summary: The study finds that the use of biochar and polyacrylamide can improve the quality of coastal saline soil and enhance rice growth and yield. The application of biochar and polyacrylamide at an optimal level can reduce soil salinity and increase soil organic matter and water-stable aggregates. Additionally, the combined application of biochar and polyacrylamide shows the most effective results for rice growth.

Summary: Synchronizing nitrogen fertilization with planting date can enhance resource use efficiency and profitability of upland rice production in Thailand. Applying 90 kg N ha(-1) of nitrogen fertilizer and planting at the end of September or start of October can maximize profitability. Long-term field investigations and adopting forecasting measures to adjust the planting date are recommended.

Summary: This study investigates the changes in fruit photosynthesis during maturation and their effects on photosynthesis and photoprotection. The results show that fruit photosynthesis contributes to the carbon requirements during maturation. The components of photosynthetic system are downregulated during early stage of maturation, leading to the increase of non-photochemical quenching for photoprotection.
