Overexpression of the NbZFP1 encoding a C3HC4-type zinc finger protein enhances antiviral activity of Nicotiana benthamiana
Copyright © 2024. Published by Elsevier B.V..
Viral diseases are crucial determinants affecting tobacco cultivation, leading to a substantial annual decrease in production. Previous studies have demonstrated the regulatory function of the C3HC4 family of plant zinc finger proteins in combating bacterial diseases. However, it remains to be clarified whether this protein family also plays a role in regulating resistance against plant viruses. In this study, the successful cloning of the zinc finger protein coding gene NbZFP1 from Nicotiana benthamiana has been achieved. The full-length coding sequence of NbZFP1 is 576 bp. Further examination and analysis of this gene revealed its functional properties. The induction of NbZFP1 transcription in N. benthamiana has been observed in response to TMV, CMV, and PVY. Transgenic N. benthamiana plants over-expressing NbZFP1 demonstrated a notable augmentation in the production of chlorophyll a (P < 0.05). Moreover, NbZFP1-overexpressing tobacco exhibited significant resistance to TMV, CMV, and PVY, as evidenced by a decrease in virus copies (P < 0.05). In addition, the defense enzymes activities of PAL, POD, and CAT experienced a significant increase (P < 0.05). The up-regulated expression of genes of NbPAL, NbNPR1 and NbPR-1a, which play a crucial role in SA mediated defense, indicated that the NbZFP1 holds promise in enhancing the virus resistance of tobacco plant. Importantly, the results demonstrate that NbZFP1 can be considered as a viable candidate gene for the cultivation of crops with enhanced virus resistance.
