Insecticidal protein

Bt toxins refer to the toxic proteins produced by insect pathogenic bacteria Bacillus thuringiensis[1]. This part was adjusted from BBa_K3686010 (BBa_K3686010), where Cry7Ca1 is a differentiate of Bt toxins with a molecular mass of 129kDa, recently isolated from Bt strain BHT-13. Cry7Ca1 is connected with GFP (BBa_E0040),and constructed into pCAMBIA-Cry7Ca1-eGFP vector.


Figure 1. Plasmid construction of pCAMBIA-Cry7Ca1-eGFP vector.

Protocol

1. Transfection of pCAMBIA-Cry7Ca1-eGFP vector through Carbon dots nanocomposite (CDP) to Nicotiana benthamiana

Coupling CDP with plant expressing vector Mix the following ingredients:

Ingredients Volumn
MES buffer(50X) 10ul
CDP(50X) 10ul
DNA(237ng/ul >10ng/ul final con) 22ul
10% glycerol 25ul
ddH2O 433ul
total 500ul

Gently mix and incubate at 37℃ for 30min.

2. Brush the mixture gently on the leaf of Nicotiana benthamiana(leaf length>10cm,Growing well) ，mark the area of brushing

3. Put the plant back in the light incubator(28℃，12h light 12h dark), repeat the process for four days at 3:00pm each day(2/4)
