Transcriptome for: MYB42 inhibits hypocotyl cell elongation by coordinating brassinosteroid homeostasis and signaling in Arabidopsis
<p><span>The precise control of brassinosteroids (BRs) homeostasis and signaling is a prerequisite for hypocotyl cell elongation in plants. Little is known, however, of such regulators of BR homeostasis and signaling. Here, we have demonstrated that MYB42 negatively regulates hypocotyl elongation through partial inhibition of BRASSINAZOLE-RESISTANT 1 (BZR1) signaling and promotion of BR inactivation. Transgenic <i><span>Arabidopsis</span></i> plants repressing the expression of <i><span>MYB42</span></i> and its paralog <i><span>MYB85</span></i> (<i><span>MYB85 RNAi;myb42</span></i>) exhibited longer hypocotyls than wild-type (WT) plants in darkness, while <i><span>MYB42</span></i> or <i><span>MYB85 </span></i>overexpression inhibits hypocotyl elongation. Hypocotyl length of <i><span>MYB85 RNAi;myb42 </span></i><span>plants can</span><i> </i><span>be </span>resorted <span>into WT level by </span><i><span>MYB42 </span></i>overexpression<span>. </span><span>MYB</span><span>42</span> inhibits hypocotyl elongation by mediating BR signaling, because <i><span>MYB42 </span></i>expression is repressed with BR treatment and in the dominant BR mutant <i><span>bzr1-1D</span></i><span>,</span> and <span>mutation of</span><i> </i><span>both</span><i><span> MYB42</span></i><span> and </span><i><span>MYB85 </span></i>enhances the dwarf phenotype of the BR receptor mutant <i><span>bri1-5</span></i><span>. BZR1 directly represses </span><i><span>MYB42 </span></i><span>expression in response to BR, and </span>t<span>he</span><i> </i><span>hypocotyl length of </span><i><span>bzr1-1D</span></i> is reduced in <i><span>MYB42</span></i><span> overexpression plants but increased in</span><i><span> MYB85 RNAi;myb42 </span></i><span>plants. These results show </span><span><span>MYB42 is a negative target of BZR1</span></span><span>. Transcriptome data revealed that</span><span><span> a number of</span></span><span> BZR1-induced </span>genes associated with <span>cell elongation are down-regulated by MYB42, suggesting that </span><span><span>MYB42</span></span> may partially inhibit BZR1 signaling. In addition, MYB42 enlarges its action in BR signaling through feedback activation of <span>the </span>BR-inactivating enzyme<span> DOGT1</span>. The present study shows a MYB42-mediated multilevel system that contributes to fine regulation of BR-induced hypocotyl elongation.</span></p>

The Arabidopsis spaceflight transcriptome: a comparison of whole plants to discrete root hypocotyl and shoot responses to the orbital environment
Arabidopsis thaliana was evaluated for its response to the spaceflight environment in three replicated experiments on the International Space Station. Two approaches were used; GFP reporter genes were used to collect gene expression data in real time within unique GFP imaging hardware and plants were harvested on orbit to RNAlater for subsequent analyses of gene expression with using Affymetrix and SAGE transcriptome analyses. Three tissue types were examined (leaves hypocotyls and roots) and compared to analyses conducted with whole plants. Transcriptome analyses with whole plants suggested that the spaceflight environment had little impact on the transcriptome of arabidopsis however closer examination of selected tissues revealed that there are a number of tissue-specific responses that arabidopsis employs to respond to this novel environment
