The mutation of a PECTATE LYASE-LIKE gene is responsible for the Yellow Margin phenotype in potato.

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
key messageThe yellow margin (ym) gene was mapped to a 30-kb genomic region in potato and the mutation of a pectate lyase gene led to this phenotype. The practice of clonally propagating potato (Solanum tuberosum L.), which has been lasted for thousands of years, has caused the accumulation of deleterious alleles. Despite yellow margin (ym) being a common cause of a detrimental weak-vigor phenotype and reduced yield in diploid potato, the underlying gene has eluded discovery to date. In this paper, we mapped the ym gene to a 30-kb region containing four annotated genes. Among them, PGSC0003DMG402023481 encodes a pectate lyase-like gene (StPLL) with lower expression in ym plants than in the wild-type plants. PCR amplification confirmed a 4.1-kb deletion in the mutant allele of StPLL. Knockout of StPLL in diploid potato resulted in a similar phenotype with the ym plants. This study not only characterizes the ym allele but also provides the molecular tools to select and purge it from populations, while also deepening our understanding of the morphogenesis in potato.
