Fig. 1. T-DNA insertion mutations in ARF6 and ARF8. (A) Locations
of T-DNA insertions. Horizontal bars represent ARF6 (At1g30330) and
ARF8 (At5g37020) -coding regions, with exons (black) and introns
(white) indicated. (B) RNA gel blot hybridization using ARF6 and
rDNA probes. (Left panel) RNA from 8-day-old wild-type seedlings,
arf6-2 mutant seedlings or wild-type flowers, stems, leaves or roots.
(Right panel) RNA from wild-type or mutant flowers. (C) RNA gel blot
hybridization using ARF8 and rDNA probes. Left panel, RNA
from wild-type seedlings, arf8-3 mutant seedlings or wild-type
flowers, stems, leaves or roots. (Right panel) RNA from wild-type or mutant
flowers.
