Chromosome-Level Genome Assembly of the Leafcutter Bee Megachile rotundata Reveals Its Ecological Adaptation and Pollination Biology.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The leafcutter bee Megachile rotundata is the world's most intensively managed solitary bee, owing to its easy manipulation and high pollination efficacy. Here, a high-quality chromosome-level M. rotundata genome, covering 280.68 Mb is presented. A total of 10 701 genes are predicted, of which 93.06% are functionally annotated. Based on the new genome assembly, transposable elements, noncoding RNAs, as well as gene families associated with pollination biology and ecological adaptation are systematically characterized. Comparative genomic analysis shows a notable expansion of Toll gene family but the contraction of detoxification gene in M. rotundata genome. Surprisingly, these expanded Toll-1 genes and their downstream genes display abundant mRNA levels in diapausing prepupae. Additionally, diapausing prepupae show significantly upregulated expression of antimicrobial peptide genes and a higher survival rate after Escherichia coli exposure compared to nondiapausing prepupae, indicating an enhanced immune response during M. rotundata diapause. The M. rotundata genome provides an important foundation for understanding its ecological adaptation and optimizing its exceptional pollination efficiency in the future.
