| Title: A CCCH-type zinc finger nucleic acid-binding protein quantitatively confers resistance against rice bacterial blight disease .
| | Author: Deng H Liu H Li X Xiao J Wang S | | Journal: Plant Physiol Citation: V : 158 P : 876-89 Year: 2012 Type: MEDLINE | | Literature: oryza Field: abstract Doc ID: pub22158700 Accession (PMID): 22158700 | | Abstract: Bacterial blight is a devastating disease of rice ( Oryza sativa ) caused by Xanthomonas oryzae pv oryzae ( Xoo ) .
Zinc finger proteins harboring the motif with three conserved cysteine residues and one histidine residue ( CCCH ) belong to a large family .
Although at least 67 CCCH-type zinc finger protein genes have been identified in the rice genome , their functions are poorly understood .
Here , we report that one of the rice CCCH-type zinc finger proteins , C3H12 , containing five typical CX ( 8 ) -CX ( 5 ) -CX ( 3 ) -H zinc finger motifs , is involved in the rice-Xoo interaction .
Activation of C3H12 partially enhanced resistance to Xoo , accompanied by the accumulation of jasmonic acid ( JA ) and induced expression of JA signaling genes in rice .
In contrast , knockout or suppression of C3H12 resulted in partially increased susceptibility to Xoo , accompanied by decreased levels of JA and expression of JA signaling genes in rice .
C3H12 colocalized with a minor disease resistance quantitative trait locus to Xoo , and the enhanced resistance of randomly chosen plants in the quantitative trait locus mapping population correlated with an increased expression level of C3H12 .
The C3H12 protein localized in the nucleus and possessed nucleic acid-binding activity in vitro .
These results suggest that C3H12 , as a nucleic acid-binding protein , positively and quantitatively regulates rice resistance to Xoo and that its function is likely associated with the JA-dependent pathway .
