Chromosome-level genome assembly of the social amoeba Heterostelium pallidum.

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
Heterostelium pallidum is the type species in the genus Heterostelium. Its distinctive characteristics in sorocarp morphogenesis such as the formation of branched structures make this species a crucial model for studying the development and evolution of dictyostelids. However, the lack of a high-quality reference genome for this species has significantly impeded reliable comparative genomic and evolutionary studies. In this study, we present the first high-quality, chromosome-level genome assembly for H. pallidum, generated by integrating Illumina, PacBio HiFi, and Hi-C sequencing technologies. The assembled genome size is 33.07 Mb with a scaffold N50 of 2.61 Mb. A total of 95.26% of the assembled sequences were anchored onto 12 chromosomes. BUSCO assessment revealed a genome completeness of 92.60%. Genome annotation identified 16.38% repetitive sequences and 10,854 protein-coding genes. This chromosome-scale assembly represents the first genomic resource of this level of quality in the genus Heterostelium, the third example in the Dictyostelia. This high-quality genome assembly serves as an essential molecular resource, which will facilitate reliable comparative genomic studies across the Dictyostelia and enable investigations into the genetic basis of its unique branched sorocarp development and the evolution of multicellularity.
