Signaling events in the hypoxic induction of alcohol dehydrogenase gene in Arabidopsis 总被引:9,自引:0,他引:9
Expression of the alcohol dehydrogenase gene (ADH) of Arabidopsis is induced during hypoxia. Because many plants increase their ethylene production in response to hypoxic stress, we examined in this report whether ethylene is involved in the hypoxic induction of ADH in Arabidopsis. We found that the hypoxic induction of ADH can be partially inhibited by aminooxy acetic acid, an inhibitor of ethylene biosynthesis. This partial inhibition can be reversed by the addition of 1-aminocyclopropane-1-carboxylic acid, a direct precursor of ethylene. In addition, the hypoxic induction of the ADH gene is also reduced in etr1-1 and ein2-1, two ethylene insensitive mutants in ethylene-signaling pathways, whereas the addition of exogenous ethylene or an increase in cellular ethylene alone does not induce ADH under normoxic conditions. Kinetic analyses of ADH mRNA accumulation indicated that an ethylene signal is required for the induction of ADH during later stages of hypoxia. Therefore, we conclude that ethylene is needed, but not sufficient for, the induction of ADH in Arabidopsis during hypoxia. 相似文献

Mammalian cells have the ability to alter their gene expression in order to survive or adapt to a variety of environment stresses including hypoxic stress. Maintaining oxygen supply has been accepted as essential for cell survival and growth. To determine the cellular and molecular changes which take place under oxygen deprivation, an NS0 cell line producing a human-mouse chimeric antibody was cultured under hypoxic conditions (<1%). Various cellular parameters such as viability, productivity, metabolism, apoptosis and cell cycle were studied and notable changes were shown to be accompanied by changes in metabolic rates. When the cells where exposed to hypoxia for 48 h, cell growth was suppressed and cell death was detected. To better understand and explore the mechanisms underpinning these biological alterations and to identify the genes involved in the genetic reprogramming, genome-wide analyses were performed using GeneChip Mouse Genome arrays. The gene expression profiling generated by the microarray technique revealed that hypoxia, even in the early stages (12h), induces significant changes in gene expression in NS0 cells. The primary responses to hypoxia within the cells were: (1) the up-regulation of pathways such as glycolysis that ultimately lead to alternative routes of ATP generation and increased oxygen availability; and (2) the down-regulation of genes involved in purine/pyrimidine and one carbon pool metabolisms required for DNA and RNA synthesis. By combining gene expression and physiological changes under hypoxia, it was possible to explore the mechanisms of hypoxia-induced alterations in more depth. 相似文献
