Genome-wide characterization and expression analysis of the bHLH gene family in response to abiotic stresses in Zingiber officinale Roscoe.
Article in BMC genomics, 2025. 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
backgroundThe basic helix-loop-helix (bHLH) transcription factors play important physiological functions in the processes of plant growth, development, and response to abiotic stresses. However, a comprehensive genome-scale study of the ginger bHLH gene family has not been documented.
resultsIn this study, 142 ZobHLH genes were identified in the ginger genome. Using Arabidopsis bHLH proteins as a reference, ZobHLH genes were classified into 15 subfamilies and unevenly distributed on 11 chromosomes of ginger. Sequence characterization, multiple sequence alignment, phylogenetic analysis, conserved protein motifs and exon-intron distribution patterns were conducted to further analyze the evolutionary relationships among these ZobHLH proteins. The results of the duplicated event analysis demonstrated that the pivotal role of segment duplication in promoting the expansion of the ZobHLH gene family. Additionally, analysis of cis-regulatory elements as well as protein interaction networks indicated the potential involvement of ginger ZobHLH family proteins in plant growth and development, and response to adversity stress. RNA-seq and RT-qPCR results showed that ZobHLH083 and ZobHLH108 play key roles in response to salt stress and waterlogging stress, respectively.
conclusionIn this study, we systematically analyzed the characteristics of ZobHLH proteins in ginger, discovering that these genes play critical roles in ginger rhizome expansion and response to salt and waterlogging stresses. The present study provides a theoretical foundation for the further research on ZobHLHs and will help to explore the functional properties of ZobHLH genes.
