“…Previous studies showed that zinc finger proteins not only have transcriptional regulatory activities but also can interact with other proteins to regulate protein activity, thus regulating plant growth and disease resistance. Rice OsZFP can directly recognize P8 protein of SRBSDV and regulate rice resistance to SRBSDV [ 35 ]. OsZFP213 interacts with OsMAPK3 to enhance the ability of scavenging ROS and synergistically regulate the salt tolerance of rice [ 36 ].…”

Transcription factors are key molecules involved in transcriptional and post-transcriptional regulation in plants and play an important regulatory role in resisting biological stress. In this study, we identified a regulatory factor, OsZF8, mediating rice response to Rhizoctonia solani (R. solani) AG1-IA infection. The expression of OsZF8 affects R. solani rice infection. OsZF8 knockout and overexpressed rice plants were constructed, and the phenotypes of mutant and wild-type (WT) plants showed that OsZF8 negatively regulated rice resistance to rice sheath blight. However, it was speculated that OsZF8 plays a regulatory role at the protein level. The interacting protein PRB1 of OsZF8 was screened using the yeast two-hybrid and bimolecular fluorescence complementation test. The results showed that OsZF8 effectively inhibited PRB1-induced cell death in tobacco cells, and molecular docking results showed that PRB1 had a strong binding effect with OsZF8. Further, the binding ability of OsZF8-PRB1 to ergosterol was significantly reduced when compared with the PRB1 protein. These findings provide new insights into elucidating the mechanism of rice resistance to rice sheath blight.

“…Increasing evidence has been implicated that zinc finger proteins also participate in biotic response in rice ( Figure 4B ). For example, a rice C2H2 zinc finger protein OsZFP was found to interact with southern rice black-streaked dwarf virus (SRBSDV) protein P8, a minor core protein of SRBSDV, which may play an important role in fijiviral infection and symptom development (Li, J. et al, 2017 ), implying that P8 may execute the infection by interfering with the host OsZFP . LSD1-related proteins in Arabidopsis are well known as remarkable disease-defensed zinc finger proteins.…”

Rice is an important cereal crop, which provides staple food for more than half of the world's population. To meet the demand of the ever-growing population in the next few decades, an extra increase in rice yield is an urgent need. Given that various agronomic traits contribute to the yield of rice, deciphering the key regulators involved in multiple agronomic trait formation is particularly important. As a superfamily of transcription factors, zinc finger proteins participate in regulating multiple genes in almost every stage of rice growth and development. Therefore, understanding zinc finger proteins underlying regulatory network would provide insights into the regulation of agronomic traits in rice. To this end, we intend to summarize the current advances in zinc finger proteins, with emphasis on C2H2 and CCCH proteins, and then discuss their potential in improving rice yield.

“…Phytophthora nicotianae biomass was considerably higher in NbCZF1-silenced plants compared to potato virus X control plants [ 19 ]. OsZFP interacts with southern rice black-streaked dwarf virus (SRBSDV) P8 and is crucial for the infection of the fijivirus and the emergence of symptoms [ 20 ].…”

BcTFIIIA Negatively Regulates Turnip Mosaic Virus Infection through Interaction with Viral CP and VPg Proteins in Pak Choi (Brassica campestris ssp. chinensis)

TFIIIA is a zinc-finger transcription factor that is involved in post-transcriptional regulation during development. Here, the BcTFIIIA gene was isolated from pak choi. Sequence analysis showed that BcTFIIIA encodes 383 amino acids (aa) with an open reading frame (ORF) of 1152 base pairs (bp). We investigated the subcellular location of BcTFIIIA and found the localized protein in the nucleus. BcTFIIIA was suppressed when the pak choi was infected by the turnip mosaic virus (TuMV). The BcTFIIIA mRNA expression level in a resistant variety was higher than that in a sensitive variety, as determined by qRT-PCR analysis. Yeast two hybrid (Y2H) assay and bimolecular fluorescence complementation (BiFC) suggested that BcTFIIIA interacts with TuMV CP and VPg in vivo, respectively, and in vitro. A virus-induced gene silencing (VIGS) experiment showed that the silencing of BcTFIIIA gene expression in pak choi promoted the accumulation of TuMV. These results suggest that BcTFIIIA negatively regulates viral infection through the interaction with TuMV CP and VPg.
