Targeting redundant gene families: A multiplexed, tissue-specific CRISPR toolbox for Arabidopsis genetic screens.
Article in Cell reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Genome-scale targeted CRISPR libraries for forward genetic screens in plants are powerful tools for functional analysis, but they suffer from limited spatial control, single sgRNA design, and poor handling of genetic redundancy. We develop multiplexed CRISPR libraries in which each construct contains two sgRNAs that simultaneously target multiple members of a gene family. The libraries can also function at the cell-type-specific and tissue levels. A double-barcoding strategy enables efficient tracking and identification of sgRNA combinations at the plant level without individually sequencing each line. Using this platform, we generate over 1,000 Arabidopsis lines that express sgRNAs targeting 707 transporter genes across 114 gene families involved in nutrient uptake. The multiplexed design increases gene coverage and editing efficiency, underscoring its improved targeting capability to reveal hidden phenotypes. This toolbox provides a scalable resource for multi-targeted genome editing and spatially precise forward genetic screens in plants.
