  309. exchange involving both plant and bacterial compounds. Phytohormones have been implicated in this process, although in&#13;
  310. many cases direct evidence is lacking. Here, we characterize the root and nodulation phenotypes of various mutant lines of pea&#13;
  311. (Pisum sativum) that display alterations in their phytohormone levels and/or perception. Mutants possessing root systems&#13;
  312. deficient in gibberellins (GAs) or brassinosteroids (BRs) exhibited a reduction in nodule organogenesis. The question of&#13;
  313. whether these reductions represent direct or indirect effects of the hormone deficiency is addressed. For example, the&#13;
  314. application of GA to the roots of a GA-deficient mutant completely restored its number of nodules to that of the wild type.&#13;
  315. Grafting studies revealed that a wild-type shoot or root also restored the nodule number of a GA-deficient mutant. These&#13;
  316. findings suggest that GAs are required for nodulation. In contrast, the shoot controlled the number of nodules that formed&#13;
  317. in graft combinations of a Bk-deficient mutant and its wild type. The root levels of auxin and GA were similar among&#13;
  318. these latter graft combinations. These results suggest that BRs influence a shoot mechanism that controls nodulation and that&#13;
  319. the root levels of auxin and GA are not part of this process. Interestingly, a strong correlation between nodule and lateral root&#13;
  320. numbers was observed in all lines assessed, consistent with a possible overlap in the early developmental pathways of the two&#13;
  321. organs.</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Subjects:</th><td valign="top" class="ep_row"><a href="http://eprints.utas.edu.au/view/subjects/260000.html">260000 Earth Sciences</a></td></tr><tr><th valign="top" class="ep_row">ID Code:</th><td valign="top" class="ep_row">2371</td></tr><tr><th valign="top" class="ep_row">Deposited By:</th><td valign="top" class="ep_row"><span class="ep_name_citation"><span class="person_name">Scholarly Publications Librarian</span></span></td></tr><tr><th valign="top" class="ep_row">Deposited On:</th><td valign="top" class="ep_row">31 Oct 2007 13:46</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">09 Jan 2008 02:30</td></tr><tr><th valign="top" class="ep_row">ePrint Statistics:</th><td valign="top" class="ep_row"><a target="ePrintStats" href="/es/index.php?action=show_detail_eprint;id=2371;">View statistics for this ePrint</a></td></tr></table><p align="right">Repository Staff Only: <a href="http://eprints.utas.edu.au/cgi/users/home?screen=EPrint::View&amp;eprintid=2371">item control page</a></p>
