The columbamine O-methyltransferase gene (CoOMT) is capable of increasing alkaloid content in transgenic tobacco plants.
Article in Molecular biology reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundIn the alkaloid biosynthetic pathways of Stephania and Rannunculaceae, columbamine O-methyltransferase (CoOMT) is an important enzyme that catalyses the formation of the tetrahydropalmatin (rotundin) biosynthesis pathway. In this study, the transgenic construct pBI121-35S-CoOMT-cmyc-Kdel was designed successfully. METHODS AND
resultsThe real-time RT-PCR results proved that the CoOMT transgene was successfully introduced into Nicotiana tabacum L. plants and produced mRNA. Its transcription levels in three transgenic tobacco lines, T0-7, T0-9, and T0-20, in the T0 generation were higher than those in wild-type tobacco plants. By analysing Western blots and ELISAs, three T0 generation transgenic tobacco lines also expressed recombinant CoOMT (rCoOMT) protein with a molecular weight of approximately 40 kDa, and its contents ranged from 0.048 μg mg
conclusionsThis is the first study on the transformation and expression of the CoOMT gene in N. tabacum plants. Initial results of the analysis of transgenic plants proved that the transgenic structure pBI121- CoOMT-Cmyc-Kdel can be used for transformation into Stephania plants.
