An evolutionarily conserved non-synonymous SNP in a leucine-rich repeat domain determines anthracnose resistance in watermelon.

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 messageA non-synonymous SNP of CC-NBS-LRR was firstly mapped to confer resistance to anthracnose in watermelon. Newly proposed LRR domain harboring the SNP is evolutionary conserved in the Cucurbitaceae and Fabaceae. Anthracnose disease caused by Colletotrichum devastates many plants. Despite the importance of the disease, the mechanisms of resistance against it are poorly understood. Here, we identified a non-synonymous single-nucleotide polymorphism (SNP) located in a leucine-rich repeat domain as a marker for resistance to anthracnose race 1 in watermelon, using a combination of genetic analyses. We validated this SNP in segregating populations and 59 watermelon accessions using high-resolution melting assays and Sanger sequencing. We demonstrated that the resulting arginine-to-lysine substitution is particularly conserved among the Cucurbitaceae and Fabaceae. We identified a conserved motif, IxxLPxSxxxLYNLQTLxL, found in 1007 orthologues/paralogues from 89 plant species, and discovered that residue 18 of this motif could determine resistance to disease caused by external invaders. This study provides a step forward in understanding anthracnose resistance in watermelon, as well as functional and evolutionary insight into leucine-rich repeat proteins.
