Abstract
Glutathione-S-transferases are essential proteins involved in cellular detoxification. The expression of GSTs has been studied extensively under various environmental stressors including xenobiotics. Here, we have isolated AtGST10, one of the phi classes of AtGSTs on the basis of its interaction with BAK1 in a yeast two-hybrid screen. BAK1 is an LRR-RLK, acting in both brassinosteroid signaling and plant defense responses. We found that AtGSTF10 binds to BAK1 through its N-terminal domain. AtGSTF10 is expressed ubiquitously in plant tissues, and the endogenous transcript level of AtGSTF10 was not induced by plant growth regulators or abiotic stressors, except drought, unlike other GSTs. Overexpression of AtGSTF10 conferred higher tolerance to salt and disturbed redox status of transgenic plants. The down-regulation of AtGSTF10 produced by RNA interference caused reduced tolerance to abiotic stress and an accelerated senescence of transformants, indicating that AtGSTF10 is involved in stress tolerance and the BAK1-mediated spontaneous cell death signaling pathway in Arabidopsis. © 2008 Elsevier Inc.
