Summary: This study investigates the presence and role of OsAAP1 transporter in various organs and tissues of rice plants. The loss of OsAAP1 function in mutant lines led to reduced growth and grain yield, as well as decreased absorption, use, and remobilization of nitrogen. The distribution of amino acids was affected in the mutant lines, resulting in accumulation in vegetative organs. Additionally, the fertility of spikelets was severely reduced. These findings highlight the critical role of OsAAP1 in amino acid translocation, spikelet fertility, and grain yield maintenance in rice.

Summary: Glutamine is produced by the assimilation of ammonium, with the OsATL6 transporter protein in rice roots playing a key role in storing excess glutamine in vacuoles under NH4+ replete conditions. Knocking down OsATL6 led to lower root glutamine content but higher concentrations in xylem sap, promoting healthier shoot growth under NH4+-replete conditions. This study highlights the temporary storage and transport role of OsATL6 in managing glutamine levels in rice plants.

Summary: In this study, a previously unrecognized auxin influx carrier subfamily gene, OsAUX5, was identified to enhance the accumulation of essential amino acids (EAAs) in rice grains. Natural variations of OsAUX5 were found to contribute to the variation of grain EAAs among rice varieties. The introduction of OsAUX5 genotype from indica rice into japonica rice significantly increased EAA levels, suggesting a potential strategy for breeding EAA-rich rice.

Summary: A comprehensive understanding of how plants sense and acquire nutrients is crucial for sustaining high crop yield. The protein OsCBL1 is involved in regulating nitrogen and phosphorus signaling in rice, especially when nitrogen is present in the form of ammonium. This research suggests that OsCBL1 plays a role in rice's response to nitrogen and phosphorus nutrition in the environment, as well as regulating rice growth through environmental nutrition.

Summary: L-Glutamic acid has been found to be an effective bio-stimulant in reducing arsenic stress in rice plants. The supplementation of Glu at an appropriate concentration can enhance photosynthesis and growth by increasing antioxidant enzymes, promoting proline metabolism, and facilitating nitrogen assimilation. This study provides insights into the role of Glu as a signaling molecule in mitigating the adverse effects of arsenic stress.

Summary: Improving nitrogen-use efficiency (NUE) is crucial for crops, especially in hybrid breeding. A study on two indica restorer lines under high and low nitrogen conditions revealed that one line (NH511) exhibited higher NUE and nitrogen uptake by increasing lateral roots and tiller numbers, compared to the other line (MH23). NH511 also showed better survival under different nitrogen-supply conditions. Transcriptomic analysis indicated that NH511 had significantly more differentially expressed genes related to nitrogen utilization compared to MH23. These findings suggest that NH511 could be used for breeding high-NUE rice varieties by regulating nitrogen-utilization genes.

Summary: In this study, a new salt-induced ASR gene (OsASR6) in rice was identified and functionally characterized. Overexpression of OsASR6 enhanced salt and oxidative stress tolerance in rice plants by reducing H2O2, malondialdehyde (MDA), Na/K, and relative electrolyte leakage. Additionally, OsASR6 was found to interact with OsNCED1, a key enzyme in ABA biosynthesis.

Summary: This study investigated the relationship between rice root characteristics and nitrogen uptake under high and low nitrogen conditions. It was found that the root characteristics were closely associated with nitrogen absorption traits and grain yield. The YD6 variety showed smaller reduction degree in root characteristics, higher nitrogen absorption traits, and grain yield under low nitrogen conditions, accompanied by higher expression of related genes. These findings provide valuable insights for developing rice varieties with low nitrogen fertilizer requirements for green rice production.

Summary: OsGRP3 acts as a positive regulator in rice drought tolerance and modulates the transcript level and mRNA stability of stress-responsive genes, including ROS-related genes. Additionally, OsGRP3 contributes to reducing ROS accumulation during drought stress. Our results suggest that OsGRP3 alleviates ROS accumulation by regulating the mRNA stability of ROS-related genes under drought stress, thereby conferring drought tolerance.

Summary: The Arabidopsis RPW8.1 gene enhances disease resistance but compromises plant growth. It has been found that RPW8.1 constitutively enhances the expression of WRKY51 transcription factor and activates salicylic acid and ethylene signaling pathways. WRKY51, in turn, suppresses RPW8.1 expression, forming a feedback regulation loop.

Summary: This study identified a secreted protein, Uv1809, as a key virulence factor in Ustilaginoidea virens-rice interactions. Uv1809 inhibits rice immunity and promotes infection by targeting and enhancing rice histone deacetylase OsSRT2-mediated histone deacetylation. CRISPR-Cas9 edited ossrt2 mutants showed broad-spectrum resistance to rice pathogens, indicating its potential as a genetic resource for breeding disease resistance.

Summary: In this study, a transcription factor called SlERF.G3-Like in tomato was found to play a role in regulating ethylene synthesis, cell wall degradation, and the flavonoid pathway. The researchers also discovered the interaction between SlERF.G3-Like and the master ripening regulator SlRIN, and increased the production of resveratrol derivatives through genetic manipulation. These findings provide insights into the coordination of fruit maturation and metabolic changes in tomatoes, and have implications for metabolic engineering.
