Plant natural products are important sources of innovative drugs, but the extraction and isolation of medicinal natural products from plants is challenging as these compounds have complex structures that are difficult to synthesize chemically. Therefore, utilizing heterologous expression systems to produce medicinal natural products in plants is a novel, environmentally friendly, and sustainable method. In this study, was used as the plant platform to successfully produce miltiradiene, the key intermediate of tanshinones, which are the bioactive constituents of the Chinese medicinal plant . The yield of miltiradiene was increased through cytoplasmic engineering strategies combined with the enhancement of isoprenoid precursors. Additionally, we discovered that overexpressing alone accelerated apoptosis in tobacco leaves. Due to the richer membrane systems and cofactors in tobacco compared to yeast, tobacco is more conducive to the expression of plant enzymes. Therefore, this study lays the foundation for dissecting the tanshinone biosynthetic pathway in tobacco, which is essential for subsequent research. Additionally, it highlights the potential of as an alternative platform for the production of natural products in plants.

A practical transition metal-free approach for the selective benzylation of NH-sulfoximines has been disclosed by using simple elemental iodine as the catalyst and -butyl hydroperoxide (TBHP) as the terminal oxidant. Comparing with known methods for the construction of -benzylated sulfoximines, our protocol shows broad substrate scope with respect to both diarylmethanes and alkylarenes, and can be conducted in air with good functional group tolerance.
