Description:
The plant growth regulator gibberellin (GA) has a profound effect on shoot development and promotes developmental transitions such as flowering. Little is known about any analogous effect GA might have on root development. In a screen for mutants, Arabidopsis plants carrying a mutation designated pickle (pkl) were isolated in which the primary root meristem retained characteristics of embryonic tissue. Expression of this aberrant differentiation state was suppressed by GA. Root tissue from plants carrying the pkl mutation spontaneously regenerated new embryos and plants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ogas, J -- Cheng, J C -- Sung, Z R -- Somerville, C -- New York, N.Y. -- Science. 1997 Jul 4;277(5322):91-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Biology, Carnegie Institution of Washington, 290 Panama Street, Stanford, CA 94305, USA. jogas@andrew.stanford.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9204906" target="_blank"〉PubMed〈/a〉
