Plant-derived pigments offer sustainable alternatives to synthetic colorants, yet their practical deployment in textiles is limited by restricted chemical diversity and low abundance. Liverworts represent a source of diverse chemical compounds, and the model liverworts Marchantia polymorpha are emerging as chassis for bioengineering and synthetic biology. Here, we report the biotechnological application of auronidins, a rare class of flavonoid pigments, as textile dyes. Using M. polymorpha, we engineered enhanced auronidin production through controlled expression of the R2R3-MYB transcription factor MpMYB14. We systematically benchmarked constitutive and inducible gene expression systems, including heat-shock, glucocorticoid receptor, and β-estradiol (XVE) circuits, identifying inducible strategies that decouple biomass accumulation from secondary metabolite production while achieving high pigment yields. Extracted auronidins were used to dye cotton yarn directly, demonstrating the feasibility of auronidins for textile dyeing. Our results establish M. polymorpha as a versatile plant chassis for programmable secondary metabolite production and introduce auronidins as a promising natural pigment platform for sustainable textile biotechnology.

Although DNA has built the framework for molecular insights from museum collections, the utility of archival RNA remains largely unexplored. Likely a consequence of the known instability of RNA relative to DNA, this has effectively precluded the use of herbaria for transcriptomics. Here, we challenge the assumption that herbaria cannot be used for transcriptomics by assembling transcriptomes from RNA extracted from herbarium specimens. Through systematic comparison of transcriptomes from fresh-collected, silica-dried, and archival specimens, we demonstrate the suitability of herbarium-derived RNA for transcriptomics. We show the practical applicability of archival mRNA by functionally validating a plant immune receptor synthesized from a specimen collected in 1956. These results contradict the community consensus regarding archival RNA and open the door to subsequent transcriptomic explorations of rare and extinct plant species. Our findings highlight the importance of preserving and utilizing the diversity embedded within herbarium collections.
