Very little is known about the physiological interactions between wheat quality and Fusarium head blight (FHB), which substantially reduces wheat grain yield and quality worldwide. In order to investigate stress-induced changes in flag leaves from plants artificially inoculated with , we screened for chlorophyll fluorescence transient at 1, 2, 4, 7 and 14 days after inoculation. Our results indicate that the maximum quantum yield of photochemistry (F/F) and the performance index (PI) were not affected by FHB, but there were significant differences in those two traits between different varieties and measurement times. FHB caused a significant reduction in the percentage of glutenins (GLU), high-molecular-weight (HMW), and low-molecular-weight (LMW) subunits in 'Kraljica' and 'Golubica', unlike 'Vulkan', where the percentage of GLU increased.

Among the vast array of functional nanoparticles (NPs) under development, nickel tungstate (NiWO) has gained prominence due to its potential applications as a catalyst, sensor, and in the development of supercapacitors. Consequently, new studies on the environmental impact of this material must be conducted to establish a regulatory framework for its management. This work aims to assess the effects of NiWO (NPs) on multiple endpoints (e.

Combined μ-XRF and XANES Track the Behavior of Pb from PM Entering Chinese Cabbage Leaves.

Environ Sci Technol

January 2025

State Key Laboratory of North China Crop Improvement and Regulation, Hebei Agricultural University, 2596 Lekai South Street, Baoding 071000, Hebei, China.

Atmospheric fine particulate matter (PM) is the main contributor to Pb accumulation in edible Chinese cabbage leaves in North China. PM-Pb primarily enters leaves via stomatal foliar uptake. However, how PM-Pb is transported and stored within the leaf cells of Chinese cabbage remains unclear.

Clonal plants can support the growth of their ramets in heterogeneous environments through clonal integration between the ramets. However, the role of clonal integration in modulating ramet photosynthesis under toxic stress, especially combined stress, is unclear. This study examines the impact of clonal integration on under three heterogeneous stresses (Pb, pyrene, and Pb+Pyrene) with two stolon connection conditions (connected and disconnected).

Regulatory Mechanism of Exogenous ABA on Gibberellin Signaling and Antioxidant Responses in Pall. Under UV-B Stress.

Int J Mol Sci

December 2024

Jilin Provincial Key Laboratory of Plant Resource Science and Green Production, Jilin Normal University, Siping 136000, China.

In the present work, we examined the effects of exogenous abscisic acid (ABA) under ultraviolet B (UV-B) exposure on gibberellin (GA) production, signaling, and antioxidant-related genes in Pall (). Using transcriptomics, acetylated proteomics, and widely targeted metabolomics, the effects of UV-B stress on and the regulatory effects of exogenous ABA on it were revealed from multiple perspectives. The findings revealed that 's antioxidant enzyme genes were differentially expressed by UV-B radiation and were substantially enriched in the glutathione metabolic pathway.
