Overexpression of a phytochrome-regulated tandem zinc finger protein gene, OsTZF1, confers hypersensitivity to ABA and hyposensitivity to red light and far-red light in rice seedlings
==Annotated Information==
===Function===
OsTZF1 is a member of the CCCH-type zinc finger gene family in rice (Oryza sativa). Expression of OsTZF1 was induced by drought, high-salt stress, and hydrogen peroxide<ref name="ref1" />.Tandem zinc finger proteins (TZFs) in plants are involved in gene regulation, developmental responses, and hormone-mediated environmental responses in Arabidopsis. However, little information about the functions of the TZF family in monocots has been reported. Here, we investigated a cytoplasmic TZF protein, OsTZF1, which is involved in photomorphogenesis and ABA responses in rice seedlings. The OsTZF1 gene was expressed at relatively high levels in leaves and shoots, although its transcripts were detected in various organs. Red light (R)- and far-red light (FR)-mediated repression of OsTZF1 gene expression was attributed to phytochrome B (phyB) and phytochrome C (phyC), respectively. In addition, OsTZF1 expression was regulated by salt, PEG, and ABA. Overexpression of OsTZF1 caused a long leaf sheath relative to wild type (WT) under R and FR, suggesting that OsTZF1 probably acts as a negative regulator of photomorphogenesis in rice seedlings. Moreover, ABA-induced growth inhibition of rice seedlings was marked in the OsTZF1-overexpression lines compared with WT, suggesting the positive regulation of OsTZF1 to ABA responses. Genome-wide expression analysis further revealed that OsTZF1 also functions in other hormone or stress responses. Our findings supply new evidence on the functions of monocot TZF proteins in phytochrome-mediated light and hormone responses.

-Please input function information here.
+* Genes in the CCCH family encode zinc finger proteins containing the motif with three cysteines and one histidine residues.  <ref name="ref1" /> <ref name="ref2" />
+* CCCH-type zinc finger proteins have essential functions in various developmental processes in plants.
 ===Expression===
-Please input expression information here.
+* The expression profile indicated that most members of this subfamily are regulated by abiotic or biotic stresses, suggesting that they could have an effective role in stress tolerance.
 ===Evolution===
-Please input evolution information here.
+* A typical CCCH protein usually contains 1–6 CCCH-type zinc finger motifs.
+* Based on the different numbers of amino acid spacers between cysteines and histidines in the CCCH motif, a consensus sequence for these  was defined as C-X 4–15 -C-X 4–6 -C-X 3 -H (X represents any amino acid) based on the whole-genome analysis of rice and Arabidopsis CCCH proteins <ref name="ref1" /> <ref name="ref2" />
