Comparative genomics uncovers evolutionary drivers of locust migratory adaptation.
Article in BMC genomics, 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
backgroundLocust migration is one of the main causes of locust plagues. While existing research has highlighted the adaptive migratory capabilities of locusts, the evolutionary patterns of their migration remain elusive. This study aims to explore these evolutionary patterns of locust migratory behavior at the genomic level. To achieve this, we conducted comparative genomics analysis using genomic data from 10 locust species with diverse migratory tendencies.
resultsWe identified 1064 genes showing signatures of positive selection in five migratory locust species using a dN/dS model. The BUSTED-PH model revealed 116 genes associated with migratory phenotypes. Gene ontology enrichment analysis indicated that these genes were predominantly related to metabolism and mitochondria-related pathways through both methods. Additionally, the evolutionary rate (RER) analysis between migratory and non-migratory locusts revealed significant divergence in energy metabolism pathways. Notably, of the genes analyzed, the SETX gene consistently showed evidence of positive selection across all five migratory species.
conclusionsThe findings suggest that the evolution of migratory behavior is associated with increased selective pressure on metabolism and mitochondria-related pathways. Hundreds of genes undergo selective changes during repetitive transitions to migratory behavior. These findings enhance our understanding of the genetic and phenotypic relationships underlying different locust migratory behaviors, providing important data for understanding the biological mechanisms behind locust outbreaks.
