The PsiYAB11, PtoYAB11 PSC , and PtoNGAL1 genes were cloned into the pGADT7-rec vector (Clontech, Mountain View, CA, USA) with the GAL4 activation domain. The promoters of PtoNGAL1, PtoCUC2, and PtoRBCL were inserted into a pAbAi-BR yeast-integrating vector (Clontech), which was used as a bait-reporter construct. pGADT7-PsiYAB11, pGADT7-PtoYAB11 PSC , pGADT7-PtoNGAL1, and pAbAi-Pro (PtoNGAL1, PtoCUC2, and PtoRBCL) were co-transformed into the Y1HGold yeast strain using a Matchmaker One-Hybrid Library Construction and Screening Kit (Clontech). The full-length CDS of PsiYAB11 was inserted into the pCzn1 vector (Zoonbio, Nanjing, China) to produce recombinant PsiYAB11 in Escherichia coli BL21. The His-PsiYAB11 fusion protein was purified using PureCube Ni-NTA Agarose (Cube Biotech, Monheim, Germany). Reactions were incubated at 25°C for 30 min after adding 2 mg of protein from the His purification eluate. The primers and probes used for these analyses are listed in Supplemental Table 7 (Supplemental Methods 11).

The PsiYAB11 and PtoYAB11 PSC genes were cloned into the pGADT7-rec vector (Clontech, Mountain View, CA, USA) with the GAL4 activation domain. The promoters of PtoNGAL1, PtoNGAL1, PtoCUC2, PtoRBCL, PtoATPA, PtoATPE and PtoPSBB were inserted into a pAbAi-BR yeast-integrating vector (Clontech), which was used as a bait-reporter construct. pGADT7-PsiYAB11, pGADT7-PtoYAB11 PSC , and pAbAi-Pro (PtoNGAL1, PtoNGAL1, PtoCUC2, PtoRBCL, PtoATPA, PtoATPE and PtoPSBB) were co-transformed into the Y1HGold yeast strain using the Matchmaker One-Hybrid Library Construction and Screening Kit (Clontech), respectively. Co-transformed yeast cells were selected on synthetic dextrose minimal medium (SD) lacking uracil (Ura) and leucine (Leu) (SD/-Ura-Leu), with or without 0.6 mg/L Aureobasidin A (AbA, Sigma-Aldrich, St. Loui, MO, USA), and were then incubated for 5 days at 30°C. pGAD-p53+p53-pAbAi and pGADT7-AD+ pAbAi-Pro were carried out in the same manner as for the positive and negative controls, respectively. The primers used for these analyses are listed in Supplemental Table S1 (Supplemental Methods S11).

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.
