Identification of a new QTL associated to reduced quinolizidine alkaloid content in white lupin (Lupinus albus, L.) and development of ultra-low alkaloid recombinants by stacking with the pauper allele.
Article in BMC plant biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundWhite lupin (Lupinus albus, L.) is a grain legume cultivated for its high agronomic and nutritional potential, despite the accumulation of bitter and potentially harmful to health quinolizidine alkaloids (QA) in the grain. Modern sweet (i.e. low alkaloid content) varieties exist, which are exploiting different recessive mutations responsible for the desired low QA chemotype. The most widely used QA-reducing determinant, pauper, has been recently identified enabling marker-assisted selection, but unstable QA content across growing seasons and environments remain a challenge in white lupin cultivation.

conclusionThe discovery of this novel locus and the development of associated PACE markers, potentially applicable for marker-assisted selection together with pauper (especially after farther validation in a larger panel of accessions), can enhance the improvement of white lupin through the development of new varieties with very low and stable alkaloid content based on stacked allele recombinants. This can help to increase the cultivation of this useful yet underutilised crop and its use for human nutrition.
