A genome-wide analysis of the small auxin-up RNA (SAUR) gene family in cotton.
Article in BMC genomics, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 30 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
backgroundSmall auxin-up RNA (SAUR) gene family is the largest family of early auxin response genes in higher plants, which have been implicated in the regulation of multiple biological processes. However, no comprehensive analysis of SAUR genes has been reported in cotton (Gossypium spp.).
resultsIn the study, we identified 145, 97, 214, and 176 SAUR homologous genes in the sequenced genomes of G. raimondii, G. arboreum, G. hirsutum, and G. barbadense, respectively. A phylogenetic analysis revealed that the SAUR genes can be classified into 10 groups. A further analysis of chromosomal locations and gene duplications showed that tandem duplication and segmental duplication events contributed to the expansion of the SAUR gene family in cotton. An exon-intron organization and motif analysis revealed the conservation of SAUR-specific domains, and the auxin responsive elements existed in most of the upstream sequences. The expression levels of 16 GhSAUR genes in response to an exogenous application of IAA were determined by a quantitative RT-PCR analysis. The genome-wide RNA-seq data and qRT-PCR analysis of selected SAUR genes in developing fibers revealed their differential expressions. The physical mapping showed that 20 SAUR genes were co-localized with fiber length quantitative trait locus (QTL) hotspots. Single nucleotide polymorphisms (SNPs) were detected for 12 of these 20 genes between G. hirsutum and G. barbadense, but no SNPs were identified between two backcross inbred lines with differing fiber lengths derived from a cross between the two cultivated tetraploids.
conclusionsThis study provides an important piece of genomic information for the SAUR genes in cotton and lays a solid foundation for elucidating the functions of SAUR genes in auxin signaling pathways to regulate cotton growth.
