Summary: In this study, six BAG members were identified in rice, classified into two groups with different functions and expression patterns. OsBAG1 and OsBAG3 were co-expressed with primary cell wall-biosynthesizing genes, OsBAG4 was co-expressed with phytohormone and transcriptional factors, and OsBAG6 was co-expressed with disease and shock-associated genes. BAGs in group I mainly participate in plant development, while BAGs in group II are involved in gene regulations and stress responses.

Summary: The study investigated the effect of the AhRS3 transgene on the expression of endogenous piceid biosynthesis genes in resveratrol-producing rice inbred lines. Results showed significant differences in resveratrol and piceid accumulation in seeds among different lines, as well as distinct expression patterns of UGT genes during seed development. These findings suggest that AhRS3 alters the expression pattern of UGT genes and key resveratrol biosynthesis genes in developing rice seeds.

Summary: This study investigates the formation of tricin-incorporated lignin and its effects on cell wall properties in rice mutants deficient in early flavonoid biosynthetic genes. The results show that the mutants lacking CHS, CHI, and CHIL are depleted of extractable flavones and tricin-lignin in the cell walls. However, the cell wall saccharification efficiencies of these mutants are similar to that of the wild-type controls, suggesting the complex metabolic consequences of tricin pathway perturbations and the relationship between lignin profiles and cell wall properties.

Summary: The study found that the starch properties of glutinous rice are mainly controlled by SSIIa, SSI, and PUL, with SSIIa playing a central role. These results reveal a complex genetic system governing the starch properties of glutinous rice, providing crucial information for promoting glutinous rice quality.

Summary: This study investigated the effects of methyl jasmonate (MJ) on rice plants under aluminum (Al) stress. The results showed that MJ improved the tolerance of rice to Al stress by maintaining ion homeostasis, enhancing the activity of antioxidant enzymes and the glyoxalase system, and increasing the accumulation of nonprotein thiol compounds.

Summary: The study found that OsTPS21 in rice produces geraniol, a monoterpene that inhibits the growth of Xoo by suppressing the expression of bacterial genes instead of damaging cell membranes. Geraniol plays an important role in JA-induced resistance against Xoo and acts as an antibacterial compound in rice.

Summary: In this study, the researchers investigated the role of zinc oxide nanoparticles (ZnO NPs) in promoting plant growth and relieving chromium-induced stress in rice seedlings. They found that exogenous supplementation of ZnO NPs enhanced the defense mechanisms of rice seedlings, increasing their tolerance against chromium stress. Additionally, this nanofertilizer reversed the inhibitory effects of chromium on growth and photosynthetic efficiency. This growth promotion was associated with the activation of antioxidative enzymes by ZnO NPs.

Summary: The rice sesquiterpene synthase II gene plays a role in the antixenosis defense mechanism against brown planthopper infestation, with differences in functionality observed between resistant and susceptible rice varieties. Single-nucleotide polymorphisms in the gene's promoter region and exon 5, as well as a seven amino acid deletion in the protein sequence, may negatively regulate gene function. Analysis suggests a correlation between SNPs in specific genes and the expression of OsSTPS2, while a 21 bp deletion in exon 5 affects the antixenosis mechanism during BPH infestation.

Summary: Plant Glycogen Synthase Kinases (GSKs) play a crucial role in regulating various physiological processes by enabling crosstalk among signaling pathways. However, the mechanisms that regulate the expression of GSK genes during plant development and stress responses are still largely unknown. This study provides a detailed analysis of GSK promoters in rice and Arabidopsis, as well as characterization of expression profiles under different conditions. The results offer valuable insights into the regulatory mechanisms and may serve as a reference for future research in other plant species.
