Ethylene Regulates Arabidopsis Development via the Modulation of DELLA Protein Growth Repressor Function Export

@article{citeulike:3577576, abstract = {Phytohormones regulate plant development via a poorly understood signal response network. Here, we show that the phytohormone ethylene regulates plant development at least in part via alteration of the properties of DELLA protein nuclear growth repressors, a family of proteins first identified as gibberellin (GA) signaling components. This conclusion is based on the following experimental observations. First, ethylene inhibited Arabidopsis root growth in a DELLA-dependent manner. Second, ethylene delayed the GA-induced disappearance of the DELLA protein repressor of ga1-3 from root cell nuclei via a constitutive triple response-dependent signaling pathway. Third, the ethylene-promoted "apical hook" structure of etiolated seedling hypocotyls was dependent on the relief of DELLA-mediated growth restraint. Ethylene, auxin, and GA responses now can be attributed to effects on DELLA function, suggesting that DELLA plays a key integrative role in the phytohormone signal response network. 10.1105/tpc.015685}, author = {Achard, Patrick and Vriezen, Wim H. and Van Der Straeten, Dominique and Harberd, Nicholas P.}, citeulike-article-id = {3577576}, citeulike-linkout-0 = {http://dx.doi.org/10.1105/tpc.015685}, citeulike-linkout-1 = {http://www.plantcell.org/cgi/content/abstract/15/12/2816}, citeulike-linkout-2 = {http://view.ncbi.nlm.nih.gov/pubmed/14615596}, citeulike-linkout-3 = {http://www.hubmed.org/display.cgi?uids=14615596}, day = {1}, doi = {10.1105/tpc.015685}, journal = {Plant Cell}, keywords = {della, gfp}, month = {December}, number = {12}, pages = {2816--2825}, posted-at = {2009-03-18 10:50:33}, priority = {2}, title = {Ethylene Regulates Arabidopsis Development via the Modulation of DELLA Protein Growth Repressor Function}, url = {http://dx.doi.org/10.1105/tpc.015685}, volume = {15}, year = {2003} }
