Abstract

The use of arbuscular mycorrhizal (AM) fungal inoculants as a means to promote plant growth is gaining momentum worldwide. Although there is an increasing number of commercial products available for various applications, the quality of these remains uncertain. We determined the AM fungal species composition in eleven inoculants from four producers by using DNA metabarcoding and compared them to the AM fungal species declared on the product labels. Our DNA metabarcoding of the inoculants revealed a concerning discrepancy between the declared and detected AM fungal species compositions of the products. While nine products contained at least one declared species, two did not contain any matching species and all inoculants but one contained additional species not declared on the product label. These findings highlight the need for better guidelines and industry standards to ensure consumer protection in the AM fungal inoculum market. Additionally, we call for caution when using commercial AM fungal inoculants in scientific experiments without confirmatory information about their species composition.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 26. 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 12 January 2024.
All research outputs
#1,455,046
of 25,382,360 outputs
Outputs from Mycorrhiza
#12
of 691 outputs
Outputs of similar age
#31,979
of 490,783 outputs
Outputs of similar age from Mycorrhiza
#2
of 9 outputs
Altmetric has tracked 25,382,360 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 94th percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 691 research outputs from this source. They receive a mean Attention Score of 3.7. This one has done particularly well, scoring higher than 98% of its peers.
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 490,783 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 93% of its contemporaries.
We're also able to compare this research output to 9 others from the same source and published within six weeks on either side of this one. This one has scored higher than 7 of them.
