to prephenate or phenylalanine by chorismate mutase. The PAL enzyme performs an essential step to convert phenylalanine (Phe) into trans-cinnamic acid (tCA). The crucial enzyme abnormal inflorescence meristem1 (AIM1) facilitates the conversion of tCA into benzoic acid (BA), which is converted for the final product, SA by benzoic acid hydrolase (Klessig et al., 2018). In downstream signaling of SA, NPR1 activated by SA serves as coactivator of transcription of PR genes. In innate situations, NPR1 is impounded in cytoplasm by way of disulfide bonds between monomers, whereas in the presence of SA, disulfide bond breaks and releases monomers that attain the nucleus to activate the transcription of PRgenes (Durrant and Dong, 2004). NPR1 interacts with WRKY transcription things, and TGA loved ones of transcription aspects facilitates their binding for the promoter region of PR genes to activate their transcription. This study reported that the genes associated to SA biosynthesis, which include PAL PLD; genes encoding for WRKY transcription variables (WRKY11, WRKY31, and WRKY41); and genes encoding PR genes PR1 and PR5 have been very upregulated in Cg-2 treated plants as in comparison with the untreated plants. It states that the SA mediated signaling pathway is completely activated from its biosynthesis to activation of defense genes. Hence, the SAR is playing a important part in systemic defense induced by Cg-2 in tomato plants. The KEGG pathway analysis stated the GlyT2 Inhibitor Storage & Stability production of various secondary metabolites associated to plant defense. Many of the secondary metabolites are synthesized via phenylpropanoid pathways. The upregulation of genes within the phenylpropanoid pathway, including phenylalanine ammonia-lyase, p-coumaroyl CoA ligase, sinapoyl coenzyme A synthetase, feruloyl CoA ligase, caffeoyl coenzyme A synthetase, sinapoyl coenzyme A synthetase, and cinnamoyl CoA synthetase. The enhancement inside the expression of genes encoding for these enzymes indicated the activation with the phenylpropanoid biosynthesis pathway that gives essentially the most crucial item, lignin which has a significant role in plant defense. Earlier reports state that priming accumulates the signaling elements that are extremely activated on exposure to abiotic or biotic pressure. The accumulation of mRNA and inactive types of mitogen-activated protein kinases, including MPK3 and MPK6 take place in primed plants (Beckers et al., 2009). When counterinoculated by plant pathogens, MPK3 and MPK6 are much more strongly activated in primed plants as compared with nonprimed plants and this is associated with elevated expression of defense genes (Beckers et al., 2009). The gene modulation of MPK signaling in many phytohormone signal transduction indicated the higher upregulation of MPK3 and MPK6 genes in tomato plants pre-inoculated with Cg-2. The raise in expression of those MPK genes mark the activation with the downstream signaling in several phytohormone signal transduction pathways. Some of the DEGs are uncharacterized for protein function. The DEGs, like Solyc01g005470.3, Solyc01g080870.3, and Solyc08g080650.two showed extra than DNA Methyltransferase Inhibitor web three-fold upregulation in Cg-2 treated plants as compared with all the manage plants. These candidate genes can be characterized further for their function to decipher their function in plant defense response. The Solyc02g036370.3 gene code for protein with HTH myb-type domain is maximum upregulated up to 8.28-fold. This gene is functionally characterized as transcription element with DNAbinding act
