Abstract:

In order to study the important role of zinc finger protein C2H2 in the stress response to soybean cyst nematode disease(SCN),lay an important foundation for further research on anti-soybean cyst nematode.The transcriptome data of SCN3 roots inoculated with Dongnong L-10(SCN-resistant)and Heinong 37(SCN-susceptible)were utilized in the present study,and the differentially expressed gene,GmC2H2-2like,was screened out.The localization of this gene was observed under the inverted fluorescence microscope.The gene was bioinformatically analyzed,and its overexpression vector was cloned and constructed to transform soybean hairy roots to study its resistance function against cyst nematode disease.The results showed that GmC2H2-2like encoded 410 amino acid residues,with a molecular weight of 45.77 ku,an isoelectric point of 8.73,and 47 phosphorylation sites,and the protein tertiary structure contained four structures,namely,α-helix(25.61%),random coil(57.32%),extended strand(13.66%),and β-turn(3.14%);the results of the subcellular localization revealed that the encoded protein was located in the nucleus;analysis of the overexpressed trans-GmC2H2-2like soybean hairy roots revealed that the number of cyst nematodes per unit area of the root tissue was significantly lower than that of the empty vector control,suggesting that GmC2H2-2like has the function of inhibiting cyst nematodes.
