中文摘要 | WRKY proteins play crucial roles in various plant processes. An AtWRKY12 homologous gene, namedMlWRKY12, was isolated from Miscanthus lutarioriparius. The MlWRKY12 gene encodes a WRKY transcrip-tion factor belonging to the group IIc subfamily. MlWRKY12 is a nuclear protein. Gene expression patternanalysis revealed a relatively high MlWRKY12 expression level in rhizomes, stems and leaf sheaths. In situhybridization analysis further demonstrated that MlWRKY12 was expressed in vascular bundle sheath,sclerenchyma and parenchyma tissues. The heterologous expression of MlWRKY12 in an atwrky12 back-ground mutant successfully rescued the phenotype of pith cell walls caused by the defect of AtWRKY12.Most strikingly, the transgenic Arabidopsis plants overexpressing MlWRKY12 exhibited early flowering.The transcript abundance of flowering related genes was measured by quantitative RT-PCR analysis,suggesting that overexpression of MlWRKY12 in Arabidopsis had a significant impact on the expres-sion level of CONSTANS (CO). Moreover, the expression levels of FLOWERING LOCUS T (FT), LFY (LEAFY),APETALA1 (AP1), CAULIFLOWER (CAL) and FRUITFULL (FUL) were upregulated in transgenic plants. Theseresults demonstrated the conserved function of MlWRKY12 existing in secondary cell wall formation ofmonocotyledonous species and implied a possible impact of MlWRKY12 on flowering control. |
英文摘要 | WRKY proteins play crucial roles in various plant processes. An AtWRKY12 homologous gene, named M, was isolated from Miscanthus lutarioriparius. The MlWRKY12 gene encodes a WRKY transcription factor belonging to the group llc subfamily. MlWRKY12 is a nuclear protein. Gene expression pattern analysis revealed a relatively high MlWRKY12 expression level in rhizomes, stems and leaf sheaths. In situ hybridization analysis further demonstrated that MlWRKY12 was expressed in vascular bundle sheath, sclerenchyma and parenchyma tissues. The heterologous expression of MlWRKY12 in an atwrky12 background mutant successfully rescued the phenotype of pith cell walls caused by the defect of AtWRKY12. Most strikingly, the transgenic Arabidopsis plants overexpressing MlWRKY12 exhibited early flowering. The transcript abundance of flowering related genes was measured by quantitative RT-PCR analysis, suggesting that overexpression of MlWRKY12 in Arabidopsis had a significant impact on the expression level of CONSTANS (CO). Moreover, the expression levels of FLOWERING LOCUST (FT), LFY (LEAFY), APETALA1 (AP1), CAULIFLOWER (CAL) and FRUITFULL (FUL) were upregulated in transgenic plants. These results demonstrated the conserved function of MlWRKY12 existing in secondary cell wall formation of monocotyledonous species and implied a possible impact of MlWRKY12 on flowering control.
