Abstract
We characterized the expression pattern of Atropa belladonna salicylic acid (SA) carboxyl methyltransferase gene, AbSAMT1, encoding S-adenosyl-L-methionine (SAM): SA carboxyl methyltransferase (SAMT) in A. belladonna, after the application of biotic and abiotic stresses to plants. AbSAMT1 was expressed after treatments of exogenous SA and also 1,2-benzisothiazole-1,1-dioxide (BIT), which is a chemical inducer related to the SA-dependent response. Expression of the AbSAMT1 gene was also induced by infection of A. belladonna plants with Pseudomonas syringae pv. tabaci (Pst), when distinctive disease resistance symptoms were observed. Moreover, it was confirmed that the expression of the AbSAMT1 gene was also induced by physical wounding and methyl jasmonate (MeJA), as well as the disease resistance response. These results suggest that AbSAMT1 may play a dual regulation role of distinct signaling in A. belladonna plants, namely the signaling pathway of the SA-dependent response, and also a jasmonic acid (JA) dependent response in local regions.
