One of the conceptual turning-points regarding the significance of these compounds in plants occurred in the second half of the 1970s, when the ascorbate-glutathione pathway was first characterized as a chloroplastic antioxidative process. Now known as the Foyer-Halliwell-Asada pathway, this sequence of reactions notably links reduction of H<sub>2</sub>O<sub>2</sub>, catalysed by ascorbate peroxidase, to oxidation of NADH or NADPH, catalysed by monodehydroascorbate reductase and glutathione reductase.

The seed-embryo replacement method was used to determine the mechanism of thermodormancy induction in the endospermic seeds of Fraxinus mandshurica. Germination of \"new seeds\" after seed embryo replacement (thermodormant embryo + non-dormant endosperm, non-dormant embryo + thermodormant endosperm, thermodormant embryo + thermodormant endosperm, non-dormant embryo + non-dormant endosperm) was compared. Germination of isolated embryos in exogenous hormones and endosperm extracts, endosperm cell wall-degrading enzyme activity, and endosperm hormone content were measured. Endosperm transcriptome of non-dormant and thermodormant seeds was determined using RNA-Seq sequencing technology. The embryos of non-dormant seeds and thermodormant seeds were not dormant, and germination of embryos isolated from them was the same. The twofold dilution of endosperm extract significantly inhibited embryos growth of non-dormant and thermodormant seeds, while the germination percentage (GP) was lower than 15%. Regardless of whether the embryo of the \"new seed\" came from a thermodormant or non-dormant seed, the GP of the \"new seed\" was higher if the endosperm came from a non-dormant seed (80 and 84%, respectively). However, if the endosperm came from a thermodormant seed, GP of the new seed with an embryo from a thermodormant or non-dormant seed decreased significantly (64 and 66%, respectively). The activity of cell wall-degrading enzymes in radicle-end endosperm of thermodormant seeds was lower than that in non-radicle-end endosperm, and the activity of enzyme in radicle-end endosperm of seeds decreased significantly after cultivating for more than 5 days at high temperature (HT). ABA content in endosperm increased significantly, GA<sub>3</sub> content in endosperm decreased significantly, and GA<sub>3</sub>/ABA ratio of endosperm was significantly decreased by nearly 1/3. HT triggers stress response by activating ABA biosynthesis and the corresponding signaling pathways. Therefore, the embryo of thermodormant F. mandshurica seeds was non-dormant, and thermodormancy induction was related to changes in the endosperm. During incubation at high temperature, the softening ability of endosperm (especially in radicle-end endosperm) was significantly weakened, while ABA accumulation and GA<sub>3</sub> decomposition in endosperm significantly enhanced the inhibition of germination by endosperm. High temperature strongly activated ABA-related signaling pathways and stress response mechanisms in endosperm.

Maize (Zea mays L.) is an important multipurpose cereal crop that contributes to global feed and food demands and is persistently under the attack of several pests of different feeding guilds. However, concerns over the drawbacks of extensive pesticide use in natural ecosystems, including health hazards and the need for cost-effective pest control strategies, are growing. Wide opportunities are available to harness native plant resistance and natural enemies for insect pest management. In this context, it is critical to understand the biochemical basis of maize genotype resistance to insects from various feeding guilds as well as their inter-guild interactions. The critical role of various herbivore-induced plant volatiles (HIPVs) in mediating tritrophic interactions between maize plants, insect pests, and their natural enemies should be considered when developing strategies for pest management. This review synthesizes the important maize defense systems against different feeding guild pests, shedding light on recent progress and insights into the long-recognized maize defense compounds.

However, whether the miR156/SPL module functions in nitrate-mediated apple lateral root development remains largely unknown. Here, we revealed the role of miR156/SPL module in regulating lateral root development and root nitrogen uptake in both apple and Arabidopsis. This finding showed that miR156-targeted transcription factor MdSPL23 not only regulates lateral root development but also root nitrogen uptake. The MdSPL23 is bound to the promoter of MdNLP7 to suppress its expression, thereby negatively regulating nitrogen uptake and inhibiting lateral root development in apple. In a likewise manner, the AtSPL9 involved in lateral root development in Arabidopsis is bound to the MdNLP7 homologous gene AtNLP7 to suppress its expression to regulate nitrate-mediated lateral root development.

Bryophytes are conspicuous components of the vegetation in the Brazilian savanna, particularly in the Campo Rupestre phytophysiognomy. There are two main types of Campos Rupestres, each with distinct soil characteristics: quartzitic and ferruginous. Quartzite soils are typically acidic and nutrient-poor, while ferruginous soils are rich in iron and tend to be acidic and low in nutrients. Despite these distinctions, these ecosystems share high soil aluminum (Al) content and vegetation with many Al-tolerant vascular plant species. However, the relationship between Al and bryophytes remains unexplored. We found that Campylopus lamellatus Mont. (Dicranaceae) and Polytrichum juniperinum Hedw. (Polytrichaceae) accumulate Al, despite the differences in the histolocalization within the gametophyte. C. lamellatus tends to accumulate Al apoplastically in the cell walls, whereas P. juniperinum accumulates it symplastically, potentially in vacuoles and chloroplasts. Additionally, populations of the same moss species in different studied sites of Campos Rupestres exhibited a similar pattern of accumulation, as our data indicated the pH and Al content of the soils were comparable.
