AsgeneDB
for functional profiling of
As
metabolism in
metagenomes
from freshwater, hot spring, marine sediment, and soil (a) Comparison of
the number of As metabolism gene families detected using KEGG, eggNOG,
COG, arCOG, KOG and AsgeneDB
in
environmental samples.
“***”
indicates that the use of AsgeneDB is significantly different to the use
of
the
other five databases (p < 0.001). (b) Abundances (RPKM)
of key As metabolic gene families in environmental samples among KEGG,
eggNOG, COG, arCOG, KOG, and AsgeneDB. Data are presented as mean ± SE
of all samples (standard error, n = 43). “***” indicates that the use
of AsgeneDB is significantly different to the use of the other five
databases (p < 0.001).
(c)
Abundances
of As metabolic gene families annotated by AsgeneDB in
four
different habitats.
