Understanding the triacylglycerol-based carbon anabolic differentiation in Cyperus esculentus and Cyperus rotundus developing tubers via transcriptomic and metabolomic approaches
Abstract
Background
Yellow
nutsedge
(YSD,
Cyperus
esculentus)
and
purple
(XFZ,
rotundus),
closely
related
Cyperaceae
species,
exhibit
significant
differences
in
triacylglycerol

Previous
studies
have
attempted
to
elucidate
the
anabolic
discrepancies
between
these
two
however,
lack
of
comprehensive

annotation
has
hindered
