Summary: The rice floury endosperm mutant M10 was identified and characterized, showing decreased total starch content and increased soluble sugar content. The mutated AGPL2 gene on chromosome 1 was found to be responsible for the floury endosperm phenotype. The AGPL2 mutation led to higher transcriptional and protein levels and a positive feedback regulation in M10. Overall, AGPL2 plays a critical role in starch synthesis and the MutMap method is effective for identifying floury endosperm mutant genes in rice.

Summary: DNA methylation is necessary for maintaining genome integrity, but under certain circumstances, transposable elements (TEs) can escape from this repression and reactivate transcription. This study investigated the expression patterns of TE transcripts during rice endosperm development and found dynamic regulation of TE activity, particularly for miniature inverted-repeat TEs (MITEs).

Summary: This study investigates the role of different starch synthase (SS) isozymes in the biosynthesis of starch in rice. By using mutants with disruptions in the SSIIIb gene, it was found that SSIIIb is responsible for the synthesis of long chain amylopectin in the leaf sheath and leaf blade. On the other hand, SSI is involved in the synthesis of short chain amylopectin. These findings provide a better understanding of starch biosynthesis in different parts of rice.

Summary: This study reveals the crucial role of OsMADS14 in starch synthesis in rice. Loss of function mutations in OsMADS14 lead to a shrunken and chalky grain phenotype, as well as significantly reduced total starch and amylose content in the endosperm. The study also demonstrates that OsMADS14 directly binds to regulatory regions of starch synthesis genes and interacts with the nuclear factor NF-YB1 to promote their transcription.

Summary: The sedentary lifestyle and refined food consumption lead to obesity, type 2 diabetes, and related complications. Daily consumption of foods rich in resistant starch (RS) can potentially reduce the incidence of these diseases. However, breeding high-RS rice varieties remains challenging. In this study, we identified a high-RS mutant rs4, which had a RS content of -10.8% in cooked rice. The genetic study revealed that the loss-of-function SSIIIb and SSIIIa together with a strong Wx allele contributed to the high-RS phenotype of the rs4 mutant.

Summary: This study demonstrates a biotechnology approach to reduce grain chalkiness in rice by suppressing the transcriptional activity of V-PPase gene, resulting in reduced chalk content and the development of more translucent grains. The suppression effect is more pronounced under heat stress. Metabolomic analysis reveals that pathways related to starch and sugar metabolism are affected in the targeted rice lines, with upregulation of starch biosynthesis genes. This method shows promise in reducing grain chalkiness in rice.

Summary: A new fructokinase, OsFRK3, was identified and its knockou mutants, osfrk3-1 and osfrk3-2, were created using CRISPR/Cas9 technology. The mutants showed decreased 1000-grain weight, grain width, grain thickness, endosperm filling rate, and seed total starch content, while the levels of sucrose and fructose were increased. The expression levels of OsGBSS1, OsBEIIb, OsPFP1 beta, and OsAGPL1 were significantly decreased in the mutants. These results suggest that OsFRK3 positively regulates starch accumulation by influencing sugar metabolism.

Summary: This study identified the P-type PPR protein PPR5 in rice as crucial for mitochondrial function and endosperm development, by controlling the cis-splicing of mitochondrial nad4 intron 3. Loss of PPR5 function resulted in decreased ATP production, upregulation of alternative oxidases expression, and abnormal mitochondrial morphology, impacting starch and protein content in the endosperm.

Summary: In this study, it was discovered that a PDZ-domain-containing protease (Prc) regulated the expression of esrB and T3/T6SSs in different manners at different growth stages. Additionally, Prc mediated the regulation of environmental acidic signals on the expression of esrB. Mutation of esrA impaired E. piscicida virulence expression irrespective of the ambient acidic signals. These findings provide a comprehensive understanding of the virulence regulation upon sensing the environmental acidic signals in bacterial pathogens.

Summary: Reasonable selection of process parameters can affect the temperature and flow fields of metal liquid in the mold cavity and achieve the desired casting organization. This study simulated the temperature and flow fields of high molybdenum cast iron casting under different casting temperatures and mold preheating temperatures. The results indicate that casting temperature has a strong impact on the movement state of the metal liquid, while mold preheating temperature influences the solidification rate and cooling time of the casting.

Summary: This research reports the first sensitive and selective fluorescent off-on UGT1A10 probe substrate called UPr6, which can be used to monitor the function of UGT1A10 in biological systems. Through a collaborative modification strategy, the researchers designed UPr6 by introducing a rigid propyl morpholine group and a methoxy group to the amide and 4'-phenoxy positions, respectively. The study also discovered two natural products from licorice as potent UGT1A10 inhibitors, which improved the sensitivity of CPT-11 against a resistant human cancer cell line. This work established a feasible strategy for designing isoform-specific UGT probe substrates.

Summary: In this study, an analytical treatment was conducted to quantitatively evaluate the growth retardation of bainitic transformation (BT) in HSLA steels. By analyzing the thermodynamic driving force ΔG and kinetic energy barrier Q, along with modeling the transformed fraction, unified expressions for thermo-kinetic correlation and generalized stability (GS) were derived. The current model, based on a proposed criterion of high ΔG-high GS, can be used to design the BT to produce bainitic microstructure with high strength and high plasticity, as confirmed by experimental results.
