Mapping and identification of QTLs for low light tolerance traits in grapevine.
Article in BMC plant biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundLow light is a major limiting factor in greenhouse grapevine cultivation, particularly during winter and early spring. To investigate the genetic basis of low light tolerance, a population of 198 F
resultsSNP markers were converted into bin markers using the self-developed VCF_to_binMap analysis pipeline, and a genetic map was constructed containing 19 linkage groups with a total length of 1161.95 cM and an average marker distance of 0.71 cM. Phenotypic analysis revealed significant segregation for chlorophyll content and light compensation point (LCP) in the F1 population, with traits approximately following a normal distribution. QTL mapping identified three significant QTLs associated with chlorophyll a content, four with chlorophyll b content, and one with total chlorophyll content, all located on linkage group LG17. Additionally, one significant QTL related to LCP was mapped to LG8. Transcriptome sequencing of extreme phenotype plants and correlation analysis identified two MYB transcription factors (Vitvi17g00232 and Vitvi17g00309) and one STN8-encoding gene (Vitvi08g02097) within the QTL intervals, suggesting their potential roles in low light tolerance.
conclusionsThis study provides insights into the genetic mechanisms underlying low light tolerance in grapevines and identifies candidate genes for further functional validation. The findings contribute to the development of grapevine varieties with improved low light tolerance, supporting sustainable greenhouse cultivation practices.
