| Abstract |
Glucosinolates (GSLs) and phenolic compounds (PCs) are biologically active and involved in the defense reaction of plants; these compounds have a beneficial effect on human health. In this study, we described the influence of biologically synthesized silver nanoparticles (Ag NPs) to enhance the phytochemicals (GSLs and PCs), their transcription levels, and their biological activities in genetically transformed root cultures (hairy root cultures) of Brassica rapa. The concentrations of silver and reactive oxygen species (malondialdehyde and hydrogen peroxide) were highly elevated in the Ag NP-elicited hairy roots (HRs). Glucosinolates (glucoallysin, glucobrassicanapin, sinigrin, progoitrin, gluconapin, 4-methoxyglucobrassicin, 4-hydroxyglucobrassicin, glucobrassicin, neoglucobrassicin, and gluconasturtiin) and their transcripts (MYB34, MYB51, MYB28, and MYB29) were significantly enhanced in the Ag NP-elicited HRs. Moreover, the phenolic compounds (flavonols, hydroxybenzoic, and hydroxycinnamic acids) were significantly enriched in the Ag NP-elicited HRs. Total phenolic and flavonoid concentrations and their transcripts (PAL, CHI, and FLS) were higher in the Ag NP-elicited HRs than in the non-elicited HRs. Additionally, biological (antioxidant, antimicrobial, and anticancer) activities were significantly higher in the Ag NP-elicited HRs than in the non-elicited HRs. The Ag NP-elicited HR cultures offered an efficient and promising in vitro method to increase the production of health-promoting bioactive compounds, which may be useful in nutraceutical and pharmaceutical industries. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 30 July 2018.
All research outputs
#22,835,295
of 25,461,852 outputs
Outputs from Bioprocess and Biosystems Engineering
#477
of 604 outputs
Outputs of similar age
#298,485
of 341,206 outputs
Outputs of similar age from Bioprocess and Biosystems Engineering
#1
of 1 outputs
Altmetric has tracked 25,461,852 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 604 research outputs from this source. They receive a mean Attention Score of 3.1. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 341,206 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 1 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
