Mining of Candidate Genes Associated with Leaf Shape Traits in Grapes.
Article in International journal of molecular sciences, 2024. 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
As the most important organ for photosynthesis, leaves provide the main energy source for plant growth. Leaf traits affect light energy utilization and, thus, plant development and biomass. Given the high morphological variability of leaves between and within grape genotypes, phenotypic analysis is challenging. This study first evaluated leaf shape trait parameters using a specific leaf profile and area analyzer, along with genome-wide association study (GWAS) analyses, to identify additional candidate genes related to grape leaf shape traits. In the two-year analysis, 89 single-nucleotide polymorphisms (SNPs) were found to be significantly associated with leaf shape traits. These SNP loci were distributed on 18 chromosomes, of which chromosome 15 had the most relevant SNPs. We found that leaf shape-associated genes included mainly plant hormone-, ubiquitin ligase-, serine/threonine protein kinase-, transcription factor-, and cell wall metabolism-related genes. By analyzing the expression of these candidate genes on the chip, we found that they exhibited diverse expression levels in leaves at different developmental stages (young, mature, and senescent). This suggests that these genes could be considered candidates for grape leaf improvement.
