    Description: Ethylene regulates plant growth, development, and responsiveness to a variety of stresses. Cloning of the Arabidopsis EIN2 gene identifies a central component of the ethylene signaling pathway. The amino-terminal integral membrane domain of EIN2 shows similarity to the disease-related Nramp family of metal-ion transporters. Expression of the EIN2 CEND is sufficient to constitutively activate ethylene responses and restores responsiveness to jasmonic acid and paraquat-induced oxygen radicals to mutant plants. EIN2 is thus recognized as a molecular link between previously distinct hormone response pathways. Plants may use a combinatorial mechanism for assessing various stresses by enlisting a common set of signaling molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alonso, J M -- Hirayama, T -- Roman, G -- Nourizadeh, S -- Ecker, J R -- New York, N.Y. -- Science. 1999 Jun 25;284(5423):2148-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Plant Science Institute, Department of Biology, University of Pennsylvania, Philadelphia, PA 19104-6018, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10381874" target="_blank"〉PubMed〈/a〉

    Description: Ethylene (C2H4), the chemically simplest plant hormone, is among the best-characterized plant growth regulators. It participates in a variety of stress responses and developmental processes. Genetic studies in Arabidopsis have defined a number of genes in the ethylene signal transduction pathway. Isolation of two of these genes has revealed that plants sense this gas through a combination of proteins that resemble both prokaryotic and eukaryotic signaling proteins. Ethylene signaling components are likely conserved for responses as diverse as cell elongation, cell fate patterning in the root epidermis, and fruit ripening. Genetic manipulation of these genes will provide agriculture with new tools to prevent or modify ethylene responses in a variety of plants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ecker, J R -- New York, N.Y. -- Science. 1995 May 5;268(5211):667-75.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Pennsylvania, Philadelphia 19104-6018, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7732375" target="_blank"〉PubMed〈/a〉
