Effects of methyl jasmonate on the growth and triterpenoid production of diploid and tetraploid Centella asiatica (L.) Urb. hairy root cultures.
Article in Scientific reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
In this study, the effects of methyl jasmonate (MeJA) on the phytomass and triterpenoid production of diploid and tetraploid Centella asiatica hairy roots were investigated. Hairy root cultures were obtained from diploid and induced tetraploid plants of C. asiatica infected by Agrobacterium rhizogenes strain ATCC 43057. MeJA triggered triterpenoid production in both ploidy hairy roots, whereas triterpenoids were not produced in the untreated hairy roots. Among the treatments, the 50 µM MeJA treatment yielded the maximum triterpenoid production in diploid hairy roots of 27.25 ± 0.27 µg/mg Dry weight (DW) total triterpenoid at day 21. For the tetraploid hairy root cultures, the 28th-day hairy root culture produced a maximum amount of triterpenoids of 16.29 ± 6.32 µg/mg DW in response to the 50 µM MeJA treatment, whereas the 100 µM MeJA treatment produced a similar triterpenoid amount (16.31 ± 9.24 µg/mg DW) at day 14. Moreover, in response to 50 µM MeJA, we obtained different ratios of aglycone to glycoside, i.e., 1:7 and 1:2, between the diploid and tetraploid hairy root cultures. Asiaticoside was the dominant phytochemical, followed by asiatic acid and madecassic acid. This study provides valuable information for producing triterpenoids for C. asiatica commercial products and preparations by using hairy root cultures.
