Summary: This study identified the ABC transporter gene OsABCG48 as having a role in regulating cadmium accumulation in rice roots. Overexpression of OsABCG48 increased cadmium tolerance in plants, reduced root cadmium accumulation, and promoted lateral root development. These findings suggest that OsABCG48 has potential applications for engineering low-cadmium rice varieties.

Summary: This study utilized antisense constructs targeting two of the five Rubisco small subunit genes to reduce Rubisco protein content in leaves, limiting CO2 assimilation rate and resulting in a significant decrease in dry biomass accumulation and grain yield. The results suggest that knocking down multiple genes is necessary to completely reduce Rubisco accumulation in MCs.

Summary: Overexpression of EiKCS improved paraquat resistance in transgenic rice (KCSox), and pre-applied exogenous spermidine alleviated paraquat injury in rice. The mechanism of paraquat-resistance involved increased activity of antioxidant enzymes and overproduction of endogenous polyamines, especially spermine.

Summary: Ribosome-inactivating proteins (RIPs) are cytotoxic enzymes that inhibit protein translation by depurinating rRNA. Some rice RIPs lack signal peptides and may affect stress responses mediated by methyl jasmonate.

Summary: Oryza Sativa, as an important food crop in China, is susceptible to drought. The CBL-interacting protein kinase (CIPK) OsCIPK17 plays a crucial role in plant growth, development, and environmental stress. This study investigated the specific mechanism of OsCIPK17 in response to drought tolerance in rice using transcriptional and metabonomic analysis. The findings revealed that OsCIPK17 enhances drought resistance in rice by regulating deep roots, energy metabolism pathway, and the accumulation of citric acid in the tricarboxylic acid (TCA) cycle. Exogenous experiments demonstrated that OsCIPK17 responds to citric acid, involving the auxin metabolism pathway, and improves drought resistance. This research provides new insights into rice drought resistance.

Summary: OVATE family proteins (OFPs) are plant-specific transcription factors that regulate plant growth and development by modulating gibberellic acid (GA) biosynthesis and brassinosteroid (BR) responses. Overexpression of OsOFP22 in rice leads to morphological changes, such as reduced plant height and altered leaf shape. OsOFP22 suppresses GA and BR signal transduction by promoting DELLA protein accumulation, integrating GA and BR to regulate plant growth.

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 study explored the effects of different plant growth-promoting bacteria (PGPB) on rice productivity and quality under ozone stress, revealing that inoculation with specific bacteria could mitigate the negative impacts of elevated ozone levels on rice production. These bacteria were found to enhance indole-3-acetic acid (IAA) production, photosynthesis capability, and ascorbic acid content in rice, leading to improved yields and quality.

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: 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: 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.
