initiate
mutations
and
suppress
gene
expression,
in
those
genes
into
which
they
are
inserted
(Ayala
and
Kiger,
1987)
.
In
our
case
the
supposed
vector(s)
could
be
inserted
into
the
different
tomato
varieties,
causing
suppression
of
the
gs+
gene
and
expression
of
the
joining
gs
gene
.
The
transferring
of
the
supposed
MGE
vector
into
plant
cells
could
be
occurring,
for
example,
through
pests,
wounding
of
tissue,
by
some
type
of
infection,
etc
.
Different
forms
of
MGE
are
described
in
maize
and
in
D
.
melanogaster
(Alihanian
et
al
.
,
1985)
.
The
occurrence
of
"walking"
of
the
"green
stripes"
trait
in
plant
fruits
and
"jumping"
into
other
varieties
evidently
are
not
limited
to
only
one
described
gene,
which
is
highly
visible
.
Our
observations
show
similar
occurrences
in
the
properties
of
fruit
form
and
color
of
skin
.
The
authors
suggest
that
in
the
selection
material,
which
for
a
long
time
have
been
used
for
linear
selections
of
permanent
genetically
distinct
forms,
an
accumulation
and
increase
of
concentration
of
genetic
variables
such
as
transposon
vectors
(MGE)
occurs
.
The
latter
being
inserted
near
an
individual
gene
can
"pull
it
out"
from
one
genotype
and
transfer
it
to
other
genotypes
by
similar
infection
.
