Summary: In this study, the researchers successfully engineered the biosynthetic pathway of bacteriochlorophyll a (BChl a) in Escherichia coli, using coexpression of 18 genes. They identified the bchNBL genes as responsible for the protochlorophyllide reduction step and utilized the same module to modify the previously constructed pathway for chlorophyll a (Chl a) synthesis. Furthermore, they demonstrated the possibility of synthesizing multiple families of photosynthetic pigments in one host by engineering E. coli strains to produce not only BChl a but also carotenoids neurosporene and β-carotene.

Summary: We identified a BBX gene, PabBBX27, in poplar, which may regulate the biosynthesis of chlorophyll and improve photosynthetic efficiency. Overexpression of PabBBX27 resulted in increased chlorophyll and photosynthates content, higher photosynthetic rate and efficiency, as well as activation of genes related to chlorophyll metabolic pathway and photosynthesis. Our findings provide new insights into the molecular mechanism of chlorophyll metabolic pathway and the cultivation of new varieties with high photosynthetic utilization efficiency in poplar.

Summary: This study revealed the importance of chlorophyll in energy harvesting and recycling in plant development. The enzymes CLD1 and CHLG are involved in the dephytylation and rephytylation of chlorophyll, and their interaction with other proteins enables the efficient recycling and utilization of chlorophyll.

Summary: Land plants have developed defense mechanisms to respond to biotic and abiotic stress conditions by priming their defense responses. Priming, particularly with plant growth regulators such as phytohormones, enhances the plant's ability to respond faster and more effectively to mild stimuli. Cytokinin, a plant hormone involved in regulating photosynthesis and delaying senescence, has been less explored in terms of priming defense or stress-related responses. A comprehensive understanding of the mechanisms of cytokinin-primed defense, especially in relation to photosynthesis, would provide valuable insights into this important group of plant growth regulators.

Summary: Knowledge of plant photosynthesis, biomass, and stress resistance is important for understanding vegetation growth and restoration. However, the response of these plant traits to plant-soil interactions at different successional stages is still poorly understood. A greenhouse experiment was conducted to investigate the effects of soil from different successional stages on plant traits, and the results showed specific directional responses of plant traits to plant-soil interactions.

Summary: The environmental occurrence of phthalates is concerning for ecosystem and human health. This study investigates the effects of dimethyl phthalate on duckweed plants, revealing that high concentrations of DMP can inhibit growth, reduce pigment content and photosynthetic performance, and induce genotoxic damage in aquatic plants, highlighting the environmental risk associated with this compound.
