Molecular evolution and diversification of phytoene synthase (PSY) gene family.
Article in Genetics and molecular biology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Phytoene synthase (PSY) is a crucial enzyme required for carotenoid biosynthesis, encoded by a gene family conserved in carotenoid-producing organisms. This gene family is diversified in angiosperms through distinct duplication events. Understanding diversification patterns and the evolutionary history of the PSY gene family is important for explaining carotenogenesis in different plant tissues. This study identified 351 PSY genes in 166 species, including Viridiplantae, brown and red algae, cyanobacteria, fungi, arthropods, and bacteria. All PSY genes displayed conserved intron/exon organization. Fungi and arthropod PSY sequences were grouped with prokaryote PSY, suggesting the occurrence of horizontal gene transfer. Angiosperm PSY is split into five subgroups. One includes the putative ortholog of PSY3 (Subgroup E3) from eudicots, and the other four subgroups include PSY from both monocots and eudicots (subgroups E1, E2, M1, and M2). Expression profile analysis revealed that PSY genes are constitutively expressed across developmental stages and anatomical parts, except for the eudicot PSY3, with root-specific expression. This study elucidates the molecular evolution and diversification of the PSY gene family, furthering our understanding of variations in carotenogenesis.
