Summary: In plants, glyceraldehyde-3-phosphate dehydrogenase (GAPDH) plays an important role in photosynthesis, and it is assembled into a homotetramer (A4) or a heterotetramer (A2B2) from GAPA and GAPB subunits. By reducing the levels of GAPA and GAPB proteins, it was found that the GAPA homotetramer can compensate for the loss of GAPB, but GAPB alone cannot fully compensate for the loss of the GAPA subunit.

Summary: In this study, the lysate of Xoo bacteriophage X3 was used to synthesize MgO and MnO2 nanoparticles. The impact of these nanoparticles on plant growth and bacterial leaf blight disease were evaluated. It was found that MgONPs and MnO(2)NPs exhibited strong antibacterial effects on Xoo and were non-toxic to plants.

Summary: This study utilized a Chlamydomonas reinhardtii RuBisCO-less mutant, Delta rbcL, to investigate carbohydrate metabolism in the absence of atmospheric carbon fixation. The results showed that in Delta rbcL, ATP is generated via photosynthetic electron transfer reactions at the onset of illumination, and metabolites of the CBB cycle are responsive to light.

Summary: Oxathiapiprolin, a fungicide, effectively controls diseases caused by oomycetes. However, little research has focused on the effects of fungicides on crops. This study used transcriptomic and metabolomic analyses to investigate the physiological regulatory mechanisms of oxathiapiprolin on tobacco infected with Phytophthora nicotianae. The results showed that oxathiapiprolin increased photosynthetic rate and antioxidant enzyme activity in tobacco, and upregulated genes related to carbon metabolism, disease resistance, and amino acid synthesis. This comprehensive study provides insights into the physiological regulatory effects of oxathiapiprolin on tobacco and can contribute to the development of disease-resistant crop varieties.

Summary: Heat stress damages cool-season turfgrasses like tall fescue, but exogenous application of ALA can improve heat stress tolerance by increasing chlorophyll levels and reducing oxidative damage. ALA-treated tall fescue showed better visual characteristics, higher chlorophyll levels, and improved photosynthetic performance under heat stress, showcasing reduced oxidative damage.

Summary: Geranylgeranyl reductase (GGR) catalyzes the hydrogenation of unsaturated hydrocarbons in isoprenoid compounds, producing various pigments in organisms. Halorhodospira halochloris GGR performs a unique double hydrogenation reaction to produce bacteriochlorophylls with a tetrahydrogeranylgeranyl tail. The study also created a variant enzyme that only performs single hydrogenation, providing insights into catalytic mechanisms of multiposition reductions by a single enzyme.

Summary: A new in planta enrichment concept was developed to simultaneously select for phosphate solubilization and rhizosphere competence. Inoculating maize roots with phosphate-solubilizing bacteria led to plants showing a similar phosphorus status to those supplied with soluble phosphate. Non-destructive multispectral imaging and metabarcoding revealed the effectiveness of this method, as well as shifts in the rhizobiome towards bacteria with plant growth-promoting and P-solubilizing capacities.

Summary: The experiment showed that UVB radiation decreased the efficiency of photosynthesis in Rhododendron chrysanthum, but also led to accumulation of flavonoids, organic acids, amino acids, and fatty acids in the plant, along with enhancement of the TCA cycle and arginine biosynthesis to protect against the deleterious effects of UVB.

Summary: The application of 1-MCP plays a significant role in maintaining the post-harvest quality of horticultural crops, but a balance needs to be struck between concentration, exposure time, and crop type. Growers should understand the impact of 1-MCP application on post-harvest quality and consider different factors to enhance the likelihood of successful application.
