Multi-combination comparative transcriptome analysis response to MeJA and identifies genes putatively involved in oridonin biosynthesis in Isodon rubescens.
Article in BMC plant biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundIsodon rubescensis used in traditional Chinese medicine and has drawn attention as a rich source of oridonin, a compound reported to possess medicinal properties. Differential transcriptome analysis is known to be an effective method for gene selection of diterpene oridonin biosynthetic pathways, however, the MeJA-induced genetic responses of I. rubescens have not yet been analyzed.
resultsIn this study, comparative transcriptome analysis of JY (with oridonin) and LS (no oridonin) lines of I. rubescens with or without a methyl jasmonate (MeJA) treatment revealed 43,115 assembled unigenes, 11,253 of which were differentially expressed. We also identified a total of 5,070 statistically significant differentially expressed unigenes which respond to MeJA including 397 transcription factor (TF) unigenes, such as bHLH, ERF, NAC, and MYB. Furthermore, assignments with KEGG pathways identified 18 of 53 unigenes referring to the diterpenoid biosynthesis, 10 cytochrome P450 unigenes, and three different expression TF unigenes were speculated that these genes could regulate the synthesis of oridonin based on MeJA induced. Finally, 18 unigenes were validated by qRT-PCR, and their expression levels were matched with the sequence data. In addition, Single Nucleotide Polymorphisms (SNPs) were analyzed and 14,609 simple sequence repeats (SSRs) were detected in I. rubescens, providing further support for future genetic variation and marker-assisted selection.
conclusionsThis is the first time to study the response of related genes to MeJA treatment in I. rubescens, and some new genes were putatively involved in oridonin biosynthesis in I. rubescens. Our results provides a valuable gene resource to functionally characterize of response to MeJA and oridonin biosynthesis in I. rubescens.
