Genome-wide analysis of the rose (Rosa chinensis) NAC family and characterization of RcNAC091.
Article in Plant molecular biology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
key messageA genome-wide analysis identified 116 NAC genes in rose, including stress-related ones with different expression patterns under drought and salt stress. Silencing of RcNAC091, a member of the ATAF subfamily, decreased dehydration tolerance in rose. The NAC (NAM, ATAF, and CUC) transcription factors (TFs) are plant-specific proteins that regulate various developmental processes and stress responses. However, knowledge of the NAC TFs in rose (Rosa chinensis), one of the most important horticultural crops, is limited. In this study, 116 NAC genes were identified from the rose genome and classified into 16 subfamilies based on protein phylogenetic analysis. Chromosomal mapping revealed that the RcNAC genes were unevenly distributed on the seven chromosomes of rose. Gene structure and motif analysis identified a total of ten conserved motifs, of which motifs 1-7 were highly conserved and present in most rose NACs, while motifs 8-10 were present only in a few subfamilies. Further study of the stress-related RcNACs based on the transcriptome data showed differences in the expression patterns among the organs, at various floral developmental stages, and under drought and salt stress in rose leaves and roots. The stress-related RcNACs possessed cis-regulatory elements (CREs) categorized into three groups corresponding to plant growth and development, phytohormone response, and abiotic and biotic stress response. Reverse transcription-quantitative real-time PCR (RT-qPCR) analysis of 11 representative RcNACs revealed their differential expression in rose leaves and roots under abscisic acid (ABA), polyethylene glycol (PEG), and sodium chloride (NaCl) treatments. Furthermore, the silencing of RcNAC091 verified its role in positively regulating the dehydration stress response. Overall, the present study provides valuable insights into stress-related RcNACs and paves the way for stress tolerance in rose.
