Fig. 5. LHW expression. (A,B) Confocal images of
lhw-2 roots expressing 35S::LHW-GFP in their nuclei (green).
Expression of this transgene is sufficient to rescue the lhw-2 xylem
phenotype (B). (C-E) LHWpro::GUS reporter expression in root tips after
staining for 1, 4 or 8 hours, respectively. (F) RT-PCR of LHW
and ACTIN (ACT) expression. S, 14-dpg seedling; L, expanded
rosette leaf; RT, 5 mm of 14-dpg root tip; R, whole 14-dpg root; SAM,
transition SAM and youngest leaves; F, flower stage 8-15; 79402, 14-dpg
seedling of SALK_79402.
