Importance
of
Plant
Tissue
Culture
in
Biotechnology-
Cell
suspension
culture
in
liquid
medium
is
a
relatively
young
field
of
biotechnology.
This
technology
involves
the
large
scale
culture
of
isolated
plant
cells
under
conditions
which
induce
them
to
synthesize
the
natural
secondary
metabolites
characteristic
of
the
parent
plants
from
which
they
were
obtained.
The
techniques
of
callus
culture
and
cell
suspension
culture
have
been
reviewed
in
recent
years,
in
particular
from
the
viewpoint
of
studying
biosynthesis
and
metabolism
of
steroids
and
cardiac
glycosides.
Biotechnologists
are
also
trying
to
increase
the
synthesis
of
natural
compounds
or
new
compounds
by
higher
plant
cell
culture
as
a
result
of
mixing
or
feeding
transformable
precursors
in
the
culture
medium.
The
metabolic
process
of
transformation
or
conversion
of
such
added
precursors
into
a
natural
or
new
compound
within
the
cell
is
known
as,
biotransformation.
Biotechnologists
are
also
trying
to
augment
the
synthesis
of
medicinally
important
alkaloids
in
culture
by
means
of
a
fungal
elicitor.
