Cbx4/Pc2,
Cbx2/M33
Embryo: From the five
homologues, only
Cbx2
has been
functionally studied
and loss of function
results in perinatal
lethality, as well as
male-to-female sex
reversal, meiotic
defects and
chromosome
instability (
Baumann &
De La Fuente, 2011;
Katoh-Fukui et al.,
1998
).
Pc
Pc
loss of function is
embryonic lethal and
giving a strong
homeotic phenotype,
which is enhanced by
overexpression of
BX-
C
. Derepression of
Hox
genes in Pc
mutants (
Lewis, 1978
).
LHP1/
TLF2
A homologue of fly
and mouse
HP1
, but
localizing to
euchromatin and
interacting with the
other PRC1 members
in plants. Mutant
lhp1
plants show pleiotropic
phenotypes with
overall size reduction,
changes in leaf
morphology, early
flowering.
LHP1
is also
required for the
repression of
FLC
in
the process of
vernalization (
Gaudin
et
al., 2001
;
Sung
et al., 2006
).
