Genome-wide identification and expression analysis of GL2-interacting-repressor (GIR) genes during cotton fiber and fuzz development.

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
MAIN
conclusionGL2-interacting-repressor (GIR) family members may contribute to fiber/fuzz formation via a newly discovered unique pathway in Gossypium arboreum. There are similarities between cotton fiber development and the formation of trichomes and root hairs. The GL2-interacting-repressors (GIRs) are crucial regulators of root hair and trichome formation. The GaFzl gene, annotated as GaGIR1, is negatively associated with trichome development and fuzz initiation. However, there is relatively little available information regarding the other GIR genes in cotton, especially regarding their effects on cotton fiber development. In this study, 21 GIR family genes were identified in the diploid cotton species Gossypium arboreum; these genes were divided into three groups. The GIR genes were characterized in terms of their phylogenetic relationships, structures, chromosomal distribution and evolutionary dynamics. These GIR genes were revealed to be unequally distributed on 12 chromosomes in the diploid cotton genome, with no GIR gene detected on Ga06. The cis-acting elements in the promoter regions were predicted to be responsive to light, phytohormones, defense activities and stress. The transcriptomic data and qRT-PCR results revealed that most GIR genes were not differentially expressed between the wild-type control and the fuzzless mutant line. Moreover, 14 of 21 family genes were expressed at high levels, indicating these genes may play important roles during fiber development and fuzz formation. Furthermore, Ga01G0231 was predominantly expressed in root samples, suggestive of a role in root hair formation rather than in fuzz initiation and development. The results of this study have enhanced our understanding of the GIR genes and their potential utility for improving cotton fiber through breeding.
