Comparative transcriptomics in ferns reveals key innovations and divergent evolution of the secondary cell walls.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Ferns are essential for understanding plant evolution; however, their large and intricate genomes have kept their genetic landscape largely unexplored, with only a few genomes sequenced and limited transcriptomic data available. To bridge this gap, we generated extensive RNA-sequencing data across various organs from 22 representative fern species, resulting in high-quality transcriptome assemblies. These data enabled us to construct a time-calibrated phylogeny for ferns, encompassing all major clades, which revealed numerous instances of whole-genome duplication. We highlighted the distinctiveness of fern genetics, discovering that half of the identified gene families are unique to ferns. Our exploration of fern cell walls through biochemical and immunological analyses uncovered the presence of the lignin syringyl unit, along with evidence of its independent evolution in ferns. Additionally, the identification of an unusual sugar in fern cell walls suggests a divergent evolutionary trajectory in cell wall biochemistry, probably influenced by gene duplication and sub-functionalization. To facilitate further research, we have developed an online database that includes preloaded genomic and transcriptomic data for ferns and other land plants. We used this database to demonstrate the independent evolution of lignocellulosic gene modules in ferns. Our findings provide a comprehensive framework illustrating the unique evolutionary journey ferns have undertaken since diverging from the last common ancestor of euphyllophytes more than 360 million years ago.
