Host genome drives the microbiota enrichment of beneficial microbes in shrimp: exploring the hologenome perspective.
Article in Animal microbiome, 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
backgroundPacific Whiteleg shrimp (Litopenaeus vannamei) is an important model for breeding programs to improve global aquaculture productivity. However, the interaction between host genetics and microbiota in enhancing productivity remains poorly understood. We investigated the effect of two shrimp genetic lines, Fast-Growth (Gen1) and Disease-Resistant (Gen2), on the microbiota of L. vannamei.
resultsUsing genome-wide SNP microarray analysis, we confirmed that Gen1 and Gen2 represented distinct genetic populations. After confirming that the rearing pond did not significantly influence the microbiota composition, we determined that genetic differences explained 15.8% of the microbiota variability, with a stronger selective pressure in the hepatopancreas than in the intestine. Gen1, which exhibited better farm productivity, fostered a microbiota with greater richness, diversity, and resilience than Gen2, along with a higher abundance of beneficial microbes. Further, we demonstrated that a higher abundance of beneficial microbes was associated with healthier shrimp vs. diseased specimens, suggesting that Gen1 could improve shrimp's health and productivity by promoting beneficial microbes. Finally, we determined that the microbiota of both genetic lines was significantly different from their wild-type counterparts, suggesting farm environments and selective breeding programs strongly alter the natural microbiome.
conclusionsThis study highlights the importance of exploring the hologenome perspective, where integrating host genetics and microbiome composition can enhance breeding programs and farming practices.
