I am interested about the gravitropic response of <i>Arabidopsis</i> roots
and the involvement of Auxin and ethylene in this process. The Arabidopsis
auxin resistant mutants <i>aux1\,axr1,axr2,axr3,axr4&dwf </i>
showed a defect in root gravitropic response. Recently two auxin resistant
mutants <i>tir1-1</i>and <i>ask1-1</i> have been reported (Genes &
Development 12:198-207 & 13:1678-4691). Could anybody tell me anything
about the gravitropic nature of the root of these two mutants?
<p>Thanks in anticipation.
