As a naturally occurring steroid sapogenin, diosgenin acts as the precursor of hundreds of steroid medicines, and thereby has important medicinal value. Currently, industrial production of diosgenin relies primarily on chemical extraction from plant materials. Clearly, this strategy shows drawbacks of excessive reliance on plant materials and farmland as well as environment pollution. Due to development of metabolic engineering and synthetic biology, bio-production of diosgenin has garnered plenty of attention. Although the biosynthetic pathways of diosgenin have not been completely identified, in this review, we outline the identified biosynthetic pathways and key enzymes. In particular, we suggest heterologous biosynthesis of diosgenin in Saccharomyces cerevisiae. Overall, this review aims to provide valuable insights for future complete biosynthesis of diosgenin.

Polyphenols, rich in phenolic structures, are widely found in plants and known for disturbing the cellular oxidative stress and regulating the signal pathways of tumor proliferation and metastasis, making them valuable in cancer therapy. Polyphenols display high adherence due to the presence of phenolic hydroxyl groups, which enables the formation of covalent and non-covalent interactions with different materials. However, nonspecific adhesion of polyphenols carries significant risks in applications as polyphenols might adhere to proteins and polysaccharides in the bloodstream or gastrointestinal tract, leading to thrombosis and lithiasis.

This review discusses the research progress of regulating tree dwarfing in fruit tree rootstocks, including its definition, manifestation, mechanism and application of different rootstocks. Studies indicate that dwarfing rootstocks reduce vegetative growth while promoting reproductive growth. Compared with vigorous rootstocks, the contents of indole-3-acetic acid, cytokinin, and gibberellin in leaves is lower, while the content of abscisic acid is higher.

Pollutants from industrial emissions and traffic accumulate in urban soils as road dust, carrying heavy metals (HMs) posing ecological and health risks. Magnetic susceptibility (MS), sensitive to ferromagnetic minerals, enables rapid HM contamination assessment. This study developed the Modified Dual-Threshold MS Evaluation Plot for Soil Contamination (M-Plot) using χ and χ% indices.

Sweet potato foot rot disease caused by Diaporthe destruens (formerly Plenodomus destruens) severely affects the yield and quality of sweet potatoes. To gain basic knowledge on regulating the pathogen using indigenous soil bacteria, the following organic materials were applied to potted soils collected from a sweet potato field contaminated with D. destruens: Kuroihitomi (compost made from shochu waste and chicken manure), Soil-fine (material made by adsorbing shochu waste on rice bran), and rice bran.

The improper use of chemical pesticides threatens ecosystems and human health, highlighting the need for sustainable alternatives. Nano-pesticides and biological control agents offer a solution, and their combination can reduce pesticide usage and improve pest control efficacy. This study utilized a star polycation (SPc) to prepare a metaflumizone nano-pesticide and combined it with the egg parasitoid (Telenomus remus) for synergistic pest management.
