| Title: The C ( 2 ) H ( 2 ) -type Zinc Finger Protein ZFP182 is Involved in Abscisic Acid-Induced Antioxidant Defense in Rice ( F ) .
| | Author: Zhang H Ni L Liu Y Wang Y Zhang A Tan M Jiang M | | Journal: J Integr Plant Biol Citation: V : 54 P : 500-10 Year: 2012 Type: In-Data-Review | | Literature: oryza Field: abstract Doc ID: pub22693960 Accession (PMID): 22693960 | | Abstract: C ( 2 ) H ( 2 ) -type zinc finger proteins ( ZFPs ) are thought to play important roles in modulating the responses of plants to drought , salinity and oxidative stress .
However , direct evidence is lacking for the involvement of these ZFPs in abscisic acid ( ABA ) -induced antioxidant defense in plants .
In this study , the role of the rice ( Oryza sativa L sub . japonica cv .
Nipponbare ) C ( 2 ) H ( 2 ) -type ZFP ZFP182 in ABA-induced antioxidant defense and the relationship between ZFP182 and two rice MAPKs , OsMPK1 and OsMPK5 in ABA signaling were investigated .
ABA treatment induced the increases in the expression of ZFP182 , OsMPK1 and OsMPK5 , and the activities of superoxide dismutase ( SOD ) and ascorbate peroxidase ( APX ) in rice leaves .
The transient gene expression analysis and the transient RNA interference ( RNAi ) analysis in protoplasts showed that ZFP182 , OsMPK1 and OsMPK5 are involved in ABA-induced up-regulation in the activities of SOD and APX .
Besides , OsMPK1 and OsMPK5 were shown to be required for the up-regulation in the expression of ZFP182 in ABA signaling , but ZFP182 did not mediate the ABA-induced up-regulation in the expression of OsMPK1 and OsMPK5 .
These results indicate that ZFP182 is required for ABA-induced antioxidant defense and the expression of ZFP182 is regulated by rice MAPKs in ABA signaling .

| Title: A novel rice C2H2-type zinc finger protein lacking DLN-box/EAR-motif plays a role in salt tolerance .
| | Author: Huang J Yang X Wang MM Tang HJ Ding LY Shen Y Zhang HS | | Journal: Biochim Biophys Acta Citation: V : 1769 P : 220-7 Year: 2007 Type: MEDLINE | | Literature: oryza Field: abstract Doc ID: pub17434609 Accession (PMID): 17434609 | | Abstract: A cDNA for the gene ZFP182 , encoding a C2H2-type zinc finger protein , was cloned from rice by RT-PCR .
ZFP182 codes an 18 . 2 kDa protein with two C2H2-type zinc finger motifs , one nuclear localization signal and one Leu-rich domain .
The DLN-box/EAR-motif , which exists in most of plant C2H2-type zinc finger proteins , does not exist in ZFP182 .
The expression analysis showed that ZFP182 gene was constitutively expressed in leaves , culms , roots and spikes at the adult rice plants , and markedly induced in the seedlings by cold ( 4 degrees C ) , 150 mM NaCl and 0 . 1 mM ABA treatments .
The approximate 1 . 4 kb promoter region of ZFP182 gene was fused into GUS reporter gene and transformed into tobacco The histochemical analysis revealed that GUS expression could not be detected in transformed tobacco seedlings under normal conditions , but strongly observed in tobacco leaf discs and the vascular it issue of roots treated with NaCl or KCl .
Expression of ZFP182 in transgenic tobacco and overexpression in rice increased plant tolerance to salt stress .
These results demonstrated that ZFP182 might be involved in plant responses to salt stress .
