is a medicinal plant and an important source for the commercial production of tropane alkaloids (TAs), such as scopolamine and hyoscyamine, which are used clinically for their anticholinergic properties. In this study, we identified 16 metallocarboxypeptidase inhibitor (MCPI) genes from (), which are grouped into three subgroups based on phylogenetic relationships and are distributed across 10 chromosomes. Promoter analysis showed that most elements were related to defense and stress responses, such as drought, low-temperature, ABA (abscisic acid), GA (gibberellin), auxin, light and MeJA responsiveness.

Based on whole genome data, the identification and expression pattern analysis of the Atropa belladonna WRKY transcription factor family were conducted to provide a theoretical foundation for studying the biological functions and mechanisms of these transcription factors. In this study, bioinformatics methods were employed to identify members of the A. belladonna WRKY gene family and to predict their physicochemical properties, conserved motifs, promoter cis-acting elements, and chromosomal localization.

In a recent study, Zeng et al. uncovered 3β-tigloyloxytropane synthase (TS) in Atropa belladonna, characterizing its mitochondrial localization and substrate specificity. The discovery of this enzyme opens up new bioengineering possibilities for tropane alkaloids (TAs), enhancing the potential for sustainable agriculture and expanding our knowledge of TA biosynthesis.

Anthocyanins are water-soluble flavonoid pigments that play a crucial role in plant growth and metabolism. They serve as attractants for animals by providing plants with red, blue, and purple pigments, facilitating pollination and seed dispersal. The fruits of solanaceous plants, tomato () and eggplant (), primarily accumulate anthocyanins in the fruit peels, while the ripe fruits of () have a dark purple flesh due to anthocyanin accumulation.
