Klebsormidiophyceae sister genomes reveal multicellularity and stress adaptations.
Article in Journal of phycology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Klebsormidium and Interfilum are two closely related genera in the charophyte group Klebsormidiophyceae. Members of Klebsormidium are usually multicellular whereas those of Interfilum are unicellular. The genome of K. nitens has been sequenced using second-generation sequencing technology, but the assembled scaffolds are frequently fragmented. In this study, we re-sequenced the genomes of K. nitens using PacBio platform and obtained 15.8 Gb long reads. We also sequenced the genome of I. paradoxum and obtained 13 Gb long reads. The I. paradoxum genome assembly (81.7 Mb) included 59 contigs with N50 of 1.9 Mb, and the K. nitens assembly (132.9 Mb) included 188 contigs with N50 of 2.1 Mb. A total of 20,425 and 15,103 protein-coding genes were annotated in K. nitens and I. paradoxum, respectively. Comparative genome analyses identified 2805 gene families specific to Klebsormidiophyceae, which are enriched in gene ontology (GO) categories related to jasmonic acid (JA) biosynthesis and rRNA catabolism. Twenty-seven gene families, enriched in RNA-DNA hybrid ribonuclease activity and transmitter-gated ion channel activity, were found to have expanded in the last common ancestor of I. paradoxum and K. nitens. Several genes related to cell wall structure, including galactosyltransferase (GALT), were absent in I. paradoxum. We also found that approximately 50% of abiotic stress-related genes (e.g., late embryogenesis abundant, LEA genes) are present in land plants. The generation of K. nitens and I. paradoxum genomes and transcriptome data provides additional resources to understand the origin and evolution of land plants.
