Delighted to share our paper on neo-chromosomes! We induced centromere fission using CRISPR in Arabidopsis and increased the chromosome count from n=5 to n=6. The broken chromosomes ends quickly “healed” by adding telomeres de novo and the new karyotype is stable through mitosis and meiosis! 1/3

CRISPR-mediated centromere fission generates neochromosomes with distorted meiotic inheritance in Arabidopsis biorxiv.org/content/10.6... new preprint from us - includes changing the Arabidopsis karyotype from 5 -> 6 chromosomes using Cas9 & outcomes of 5/6 chromosome hybrid meiosis

Excited to share this story in its final form, now published in ACS Synthetic Biology. #PlantBiology #Synbio pubs.acs.org/doi/10.1021/...

Engineering Auronidin Production in Marchantia polymorpha Enables a New Class of Plant-Derived Textile Pigments

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.

Marchantia might seem an unlikely biotech crop, but it’s worth trying. In Aurore’s thesis, we pushed this concept by engineering the auronidins with MpMYB14 and using the pigments to dye cotton. It ended up giving a very unique and beautiful product. #PlantScience www.biorxiv.org/content/10.6...

Happy to announce our study that has just been published from work done during my PhD at the University of Bristol working in Prof. Jill Harrison's lab. It's about WOX genes and sporophyte development in the model moss, Physcomitrium patens. Take a look 🧵👇

@khongsamchia.bsky.social Extremely excited to share the first pre-print from my PhD project in the Carella lab, co-first authored with @khongsamchia.bsky.social 🎉 (Thread below ⬇️) www.biorxiv.org/content/10.6... Huge thanks to all co-authors and the #CarellaCapybaras for all the support 😊

Excited to have started my group @zmbp-tuebingen.bsky.social through the @dfg.de Emmy Noether program. In this project we will be looking at the mechanisms of host invasion by fungal pathogens 🍄🌱 Check it out and drop me a line if you are interested! uni-tuebingen.de/en/universit...
