Genomic-wide identification and expression analysis of R2R3-MYB transcription factors related to flavonol biosynthesis in Morinda officinalis.
Article in BMC plant biology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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 R2R3-MYB transcription factors are a crucial and extensive gene family in plants, which participate in diverse processes, including development, metabolism, defense, differentiation, and stress response. In the Lingnan region of China, Morinda officinalis is extensively grown and is renowned for its use as both a medicinal herb and food source. However, there are relatively few reports on the R2R3-MYB transcription factor family in M.officinalis.
resultsIn this study, we identified 97 R2R3-MYB genes in the genome of Morinda officinalis and classified them into 32 subgroups based on phylogenetic comparison with Arabidopsis thaliana. The lack of recent whole-genome duplication events in M.officinalis may be the reason for the relatively few members of the R2R3-MYB family. We also further analyzed the physical and chemical characteristics, conserved motifs, gene structure, and chromosomal location. Gene duplication events found 21 fragment duplication pairs and five tandem duplication event R2R3-MYB genes in M.officinalis may also affect gene family expansion. Based on phylogenetic analysis, cis-element analysis, co-expression analysis and RT-qPCR, we concluded that MoMYB33 might modulate flavonol levels by regulating the expression of 4-coumarate-CoA ligase Mo4CL2, chalcone isomerase MoCHI3, and flavonol synthase MoFLS4/11/12. MoMYB33 and AtMYB111 showed the highest similarity of 79% and may be involved in flavonol synthase networks by the STRING database. Moreover, we also identified MoMYB genes that respond to methyl Jasmonate (MeJA) and abscisic acid (ABA) stress by RT-qPCR.
conclusionsThis study offers a thorough comprehension of R2R3-MYB in M.officinalis, which lays the foundation for the regulation of flavonol synthesis and the response of MoMYB genes to phytohormones in M.officinalis.
