The
process
of
microcycle
sporulation
is
also
known
in
fungi
and
sometimes
conidia
of
aspergilli
on
germination
are
known
to
enter
microcycle
sporogenesis.
However,
unlike
in
bacteria,
microcycle
sporulation
involves
greater
synthesis
and
cellular
alterations
to
yield
a
conidiophore
and
other
structures.
The
sporulating
structures
are
much
smaller
in
size
than
the
normal
structure
Sporulation
and
spore
germination
therefore,
represent
both
the
beginning
and
end
of
morphogenesis,
both
in
fungi
and
bacteria.
Such
changes
occur
due
to
minor
shifts
in
environmental
conditions.
The
control
mechanisms
that
operate
during
morphogenesis
are
different.
The
process
is
under
genetic
control
and
a
great
deal
of
biochemistry
is
known.
Yet,
our
knowledge
of
the
exact
operation
of
the
regulatory
processes
that
allow
the
conversion
of
a
vegetative
cell
into
a
dormant
structure
is
still
incomplete
