Genetic diversity and adaptive evolutionary history of Sapindus in China: insights from whole-genome resequencing of 100 representative individuals.
Article in Plant biotechnology journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Sapindus is an important forest tree genus with utility in biodiesel, biomedicine, biochemistry and forestry. Similar to many perennial crop plants, its breeding is hampered by long generation times and lack of genetic resources. To understand the genome evolution underlying the important bioeconomic traits, we carried out a common garden experiment with 100 Sapindus core germplasm individuals representing three endemic species and 60 populations sampled throughout China. Whole genome sequencing identified a split into six populations according to species and geography. The previously uncharacterized S. delavayi and S. rarak are diploid species, and here we propose hypotheses for their speciation. Selective sweeps suggested stress responses as well as alleles of the genes CYP716A, CAMTA and HD-ZIP involved in triterpenoid saponin biosynthesis to have been under selection in natural populations, while genome-wide association analysis revealed several homologues of fatty acid biosynthesis genes to be associated with kernel fatty acid quality. Our findings elucidate the genetic structure of Sapindus in China, provide target loci for selection and suggest cultivar materials for genetic improvement.
