www.nature.com/articles/s41... It's been a long time coming, but delighted to say that the first major output from my Royal Society Fellowship is now published. 🙂 #PlantScience

The post-fertilization archegonium gene network of seedless plants contributed to the origin of seeds - Nature Communications

The authors identify conserved gene networks across fern and angiosperm reproductive development, including between the sporophyte ovule and the fern gametophyte egg-chamber. Repurposing of this netwo...

Great pleasure to summarize the up-to-date findings and share our thoughts on the functional evolution of Type I MADS-box genes! Many thanks to Journal of Experimental Botany and the editor, Rainer @ucdflowerpower.bsky.social for the invitation!

🌸 FLOWERING NEWSLETTER REVIEW 🌸 Qiu & Köhler synthesize the current knowledge of land plant Type I MADS-box transcription factors, highlighting their evolutionary history and divergence patterns, and their key roles in diverse reproductive programmes. 🔗 doi.org/10.1093/jxb/... #PlantScience 🧪

Fig. 1 (shortened, full legend in paper): Evolution of MEF2-derived MADS-box transcription factors (TFs) in green plants. The top panel shows the main subfamilies present in each extant plant lineage, focusing on the origin and diversification of Type I (M-type and MIKC*-type) TFs without detailing the further duplication within Type II (MIKCC-type) TFs. The arrows mark the sequential gene duplication events, with the numbered circles labelling the corresponding branches inferred by phylogenetic timing. The ancestral gene in the most recent common ancestor (MRCA) of green plants resembled the MEF2-type TF, with the MADS-domain (canonical definition) followed by the MEF2 domain and a non-conserved C terminus.

Thrilled to have received an ERC Advanced Grant to investigate the mechanisms and biological impact of small RNA mobility in plants. A huge thanks to my team for making this possible, and to the reviewers for their support and confidence in the project. Looking forward to getting started!

ERC Advanced Grant @erc.europa.eu for @maxplanck.de Director Claudia Köhler @claudiakohler11.bsky.social! She receives 2.5 million euros to study how mobile small RNAs can impact adaptive functional traits in plants. Congratulations!

The origin of MADS-box genes is fundamental to understanding the adaptative innovations of land plants. We are happy to have the opportunity for another round of clarification. Thank @genomebiolevol.bsky.social for providing the platform. Very professional editors and reviewers, much appreciated!

Qiu, Li & Köhler show that both Type I and Type II MADS-box genes are plant-specific duplicates derived from MEF2-type ancestors, while ancestral SRF genes were lost before the divergence of the plant lineage. 🔗 doi.org/10.1093/gbe/evag140 #genome #evolution #PlantSky

GBE | No Evidence Supports the Presence of SRF-type MADS-Box Genes in Land Plants Is there evidence that a small subset of plant Type I MADS-box genes are orthologous to animal SRF genes? Our analyses do not support this. Rather, they indicate that both plant Type I MADS-box genes and their plant-specific paralogous Type II genes are related to animal MEF2 genes.

I defended my PhD 10 years ago today. That was the least remarkable thing that happened that day. Sharing something I wrote about it last year. Since then "the horrors persist but so do we." And with dignity.

I am delighted to share our review on MADS-box genes! Supported by Claudia @claudiakohler11.bsky.social, we attempt to summarize (nearly) everything currently known about Type I MADS-box genes. Let's have fun in the MADS world and check out the fruitful giants! academic.oup.com/jxb/advance-...

The Other Giant: Functional Significance and Divergence of Type I MADS-Box Genes in the Evolution of Land Plants

Abstract. Angiosperms represent the most abundant and diverse lineage of land plants, and their evolutionary success is closely linked to major reproductiv
