Novel genes and alleles of the BTB/POZ protein family in Oryza rufipogon.
Article in Scientific reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
The BTB/POZ family of proteins is widespread in plants and animals, playing important roles in development, growth, metabolism, and environmental responses. Although members of the expanded BTB/POZ gene family (OsBTB) have been identified in cultivated rice (Oryza sativa), their conservation, novelty, and potential applications for allele mining in O. rufipogon, the direct progenitor of O. sativa ssp. japonica and potential wide-introgression donor, are yet to be explored. This study describes an analysis of 110 BTB/POZ encoding gene loci (OrBTB) across the genome of O. rufipogon as outcomes of tandem duplication events. Phylogenetic grouping of duplicated OrBTB genes was supported by the analysis of gene sequences and protein domain architecture, shedding some light on their evolution and functional divergence. The O. rufipogon genome encodes nine novel BTB/POZ genes with orthologs in its distant cousins in the family Poaceae (Sorghum bicolor, Brachypodium distachyon), but such orthologs appeared to have been lost in its domesticated descendant, O. sativa ssp. japonica. Comparative sequence analysis and structure comparisons of novel OrBTB genes revealed that diverged upstream regulatory sequences and regulon restructuring are the key features of the evolution of this large gene family. Novel genes from the wild progenitor serve as a reservoir of potential new alleles that can bring novel functions to cultivars when introgressed by wide hybridization. This study establishes a foundation for hypothesis-driven functional genomic studies and their applications for widening the genetic base of rice cultivars through the introgression of novel genes or alleles from the exotic gene pool.
