The codon-optimized GBP1 coding sequence was amplified with the primer pair ClaI_GBP1_F (5’-gacggtatcgataaaATGCCGCCACATGGTAGACG-3’) and GBP1_noSTOP_XmaI_R (5’-ataactcccgggATGGCCATATTGACGATACCAACAGC-3’) and directionally cloned into the ClaI and XmaI sites of the binary vector to produce pXCScpmv-GBP1-HAStrep. - -To generate a catalytically inactive version of GBP1, the first glutamate residue of the catalytic center (E500) was exchanged to an alanine residue via site-directed mutagenesis PCR with the primer pair GBP1_E500A_F (5’-CAGGCATCAACATCAGAAGCAGTG-3’) and GBP1_E500A_R (5’-GTTCCTACCATCTCCAAACTCAGTC-3’). - -The linearized, mutated plasmid was purified after gel electrophoresis using the NucleoSpin Gel and PCR Clean-up Kit (Macherey-Nagel, Düren, Germany). The isolated DNA fragment was treated with a self-made KLD mixture (1,000 units·mL-1 T4 polynucleotide kinase, 40,000 T4 DNA ligase units·mL-1 ligase 2,000 units·mL-1 DpnI, 1 × T4 DNA ligase buffer; all enzymes were purchased from New England BioLabs, Ipswich, USA) for 1 h at room temperature before transformation into *Escherichia coli* MachI cells. - -Plasmids were isolated using the NucleoSpin Plasmid Kit (Machery-Nagel, Düren, Germany) and sequenced to confirm the introduced mutation. Both plasmids (pXCScpmv-GBP1-HAStrep and pXCScpmv-GBP1_E500A-HAStrep) were introduced into *Agrobacterium tumefaciens* GV3101::pMP90RK strains for transient transformation of *N. benthamiana* leaf tissue. \ No newline at end of file
