Fig. 5. Root growth phenotypes of gnomR5 roots are
auxin-mediated. (A,B) Local application of NPA at the hypocotyl-root junction
of wild-type roots severely reduces lateral root formation (A) and decreases
primary root elongation (B). Plants were grown for 15 days. Differences
between treatments were significant (P<0.001). (C-H) Comparison of
(C-E) root tips and (F-H) rosette leaves after local application of NPA. (C,F)
Untreated gnomR5, (D,G) NPA-treated wild type, (E,H)
DMSO-treated wild type (control). (I) gnomR5 root meristem
collapse can be reduced by transferring seedlings to plates supplemented with
NAA. Observed numbers were significantly different from each other
(P<0.01). (J-L) Root regeneration of seedlings. (J) Comparison of
wild-type (left) and gnomR5 (right), 9 days after cutting.
(K,L) Magnification of regeneration zone of (K) wild type and (L)
gnomR5.
