overexpression of LcSAMT gene markedly enhances the methylsalicylate (MeSA) content and reduces the accumulation of salicylate (SA) in transgenic tobacco plants, the conversion of MeSA from SA leads to the depletion of the free SA pool. Overexpression of LcSAMT gene in tobacco significantly increases sensitivity of transgenic plants to drought stress, probably due to the decreased SA accumulation. Increased accumulation of ROS, elevated MDA levels, reduced proline contents, and lowered expression of APX, CAT and SOD genes are also observed in the LcSAMT transgenic tobacco plants under drought stress, which means that the LcSAMT-overexpressing transgenic tobacco plants have decreased resistance to oxidative stress in comparison with control plants under drought stress. LcSAMT-overexpressing transgenic tobacco plants display decreased abscisic acid (ABA) accumulation and reduced transcript expression of NtNCED1 and NtRD22 genes. Therefore, the increased sensitivity of transgenic plants overexpressing LcSAMT gene to drought stress might also act through an ABA-dependent pathway. Overexpression of LcSAMT decreases RWC, proline, chlorophyll content, and the photosynthetic capacity, and increases MDA content of transgenic Nicotiana tabacum plants exposed to drought stress |

salicylic acid (SA) is a phenolic compound involved in plant growth and development. Salicylic acid carboxyl methyltransferase (SAMT) can catalyze the methylation of SA with S-adenosyl-L-methionine as the methyl donor to form methyl salicylate (MeSA). Recombinant salicylic acid carboxyl methyltransferase-like gene LcSAMT from Lycium chinense negatively regulates the drought response in transgenic tobacco. Enzyme LcSAMT regulates the expression of stress-related genes in transgenic Nicotiana tabacum plants exposed to drought stress |

the expression and activities of MeSA esterase (MES), benzoic acid/SA methyltransferase (BSMT) and starch synthase (SS 1) are presumed to be involved in the defense response and monitored. Specifically, BoMES2, BoMES4_2, BoMES9 genes might be involved in the esterase activity to form free salicylate, supporting their defense activity during fungal infection. Another gene potentially involved in the esterase activity during clubroot development is BoMES9_1. Analysis of protein interaction network, overview. BoBSMT1 shows interaction with UGT74F2 and DIR1, which can play positive regulatory roles in glucosyltransferase and SAR signaling respectively |

| 2.1.1.274 | physiological function |
Brassica oleracea var. capitata production is severely affected by clubroot disease caused by the soil-borne plant pathogen Plasmodiophora brassicae. During clubroot development, methyl salicylate (MeSA) is biosynthesized from salicylic acid (SA) by salicylate methyltransferase. Methyl salicylate esterase (MES) plays a major role in the conversion of MeSA back into free SA. Analysis of the interrelationship between MES and salicylate methytransferases during clubroot development, overview |

salicylic acid carboxyl methyltransferase activity from Camellia sinensis provides the aroma compound methyl salicylate (MeSA) during the withering process of white tea. During the withering process for white tea producing, MeSA is generated by salicylic acid carboxyl methyltransferase (SAMT) with salicylic acid (SA), and the specific floral scent is formed |

AtBSMT1-overexpressing plants are not more susceptible than wild-type to either Plasmodiophora brassicae or Albugo candida. Transgenic Arabidopsis thaliana and Nicotiana tabacum plants overexpressing PbBSMT exhibit increased susceptibility to virulent Pseudomonas syringae pv. tomato DC3000 and virulent Pseudomonas syringae pv. tabaci, respectively. Gene-mediated resistance to DC3000/AvrRpt2 and tobacco mosaic virus (TMV) is also compromised in Arabidopsis thaliana and Nicotiana tabacum cv. Xanthi-nc plants overexpressing PbBSMT, respectively. Transient expression of PbBSMT or AtBSMT1 in lower leaves of Nicotiana tabacum Xanthi-nc results in systemic acquired resistance (SAR)-like enhanced resistance to TMV in the distal systemic leaves. The development of a PbBSMT-mediated SAR-like phenotype is also dependent on the MeSA esterase activity of NtSABP2 in the systemic leaves. Phenotypes, overview |
