Our
lab
is
primarily
concerned
with
disease
resistance;
however,
during
our
screen
for
disease
resistance
mutants,
we
isolated
three
putative
developmental
mutants
from
our
EMS
mutagenized
and
fast
neutron
mutagenized
seed
populations
.
We
present
these
plants
here
with
brief
descriptions,
so
that
any
lab
who
is
interested
may
obtain
these
lines
from
us
for
further
study
.
All
mutants
are
from
a
VF36
background,
and
are
transgenic
for
the
N
TMV
disease
resistance
gene
.

NST10
EMS
Putative
leaf
mutant
.
Variegated
green/yellow
patterns
on
leaves
resembling
mosaic
-
disease
symptoms,
even
though
plant
is
not
infected
with
virus
.
Is
not
impaired
in
TMV
resistance
.
Sets
fruit,
but
has
reduced
fertility
.
Yes
NST43
EMS
Dwarfed/small
in
stature
.
May
have
reduced
number
of
trichomes
.
Appears
to
have
increased
rate
of
senescence
in
leaves
.
Fruit
set
does
not
appear
to
be
affected
.
Yes
FN3/1
Fast
Neutron
"Cabbage/kale"
mutant:
Leaves
are
packed
close
together
along
the
main
stem
of
the
plant
and
all
stems
of
leaves/leaflets
are
very
thick
.
Leaflets
are
tightly
curled
under
.
Plant
does
set
fruit,
but
seed
has
not
been
collected
yet
