The full-length CDS fragments of WRKY63 were PCR-amplified and cloned into the pCR8/GW/TOPO vector (Invitrogen). Point mutation constructs were constructed by specific primer sets then cloned into the pCR8/GW/TOPO vector (Invitrogen). WRKY63 was recombined into the PK7WGF2 (Invitrogen) to generate the GFP:WRKY63 plasmid. To construct WRKY63pro::WRKY63:GFP, approximately 2-kb promoter with the genome sequence of WRKY63 was cloned into the pCR8/GW/TOPO vector (Invitrogen), then recombined into the pMDC107 binary vector. The transgenic plants were generated by using the floral dip method.

Sequences of all oligonucleotides used in this study can be found in Supplementary Table S1. yCOQ8 was amplified from yeast genomic DNA, cloned into pCR8/GW/TOPO vector (Thermo Fisher, Waltham, MA, USA) and then transferred to the centromeric (CEN) pCM189 yeast expression vector adapted to the Gateway cloning system (Thermo Fisher, Waltham, MA, USA). The coding sequence of human COQ8B was amplified from human cDNA and cloned into pCR8/GW/TOPO vector (Thermo Fisher, Waltham, MA, USA). We used a reverse primer that included the sequence encoding either the V5 or the HA tag. COQ8BV5 was then subcloned into the pCM189 yeast expression vector, whereas COQ8HA was cloned into the pCDNA5 using the Gateway cloning system.
The yCOQ8COQ8B and yCOQ3COQ8B hybrid genes were constructed by sequential PCR as described (Nguyen et al., 2014) and cloned in pCM189. Both constructs encode the V5 epitope on the 3′terminus.
All mutagenesis reactions were performed on fragments cloned in pCR8/GW/TOPO vector using the QuikChange Lightning site‐directed mutagenesis kit (Agilent, Santa Clara, CA, USA). The correctness of all constructs was confirmed by direct sequencing.

Check if the same lab product or an alternative is used in the 5 most similar protocols
The pas2-1 mutants are EMS alleles in Col-0 background. To generate the PPAS2::GFP-PAS2 (GFP-PAS2) transgenic line, a DNA fragment containing 1.5-kb PAS2 promoter and the full-length cDNA clone of PAS2 were amplified using primers in Table S1 online and cloned into the PCR8/GW/TOPO vector (Thermo Fisher Scientific, Waltham, MA, USA). After sequencing, both fragments were cloned to the pH7WGF2 vector [55 (link)]. The verified construct was introduced into pas2-1 using Agrobacterium tumefaciens-mediated transformation [56 (link)]. A GFP-PAS2-expressing Arabidopsis thaliana transgenic line was crossed with one expressing mCherry-SYP32, -Got1p, -VTI12, -RabA1g or -RabG3f [46 (link)] to generate dual labeled transgenic lines, respectively. The point mutations were generated directed on the GFP-PAS2 construct using a QuikChange® Site-Directed Mutagenesis Kit (Agilent, Santa Clara, CA, USA). The mutated constructs were transformed into pas2-1 heterozygous background. The T1 generation was screened for pas2-1 homozygous plants. A GFP-CESA3-expressing Arabidopsis thaliana transgenic line [3 (link)] was crossed with pas2-1 heterozygous plants. F2 seedlings homozygous for pas2-1 by PCR genotyping were used for confocal imaging and other analysis.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
