Lee, Hyemin. 2014. Drama of Resistance, Resistance of Drama: Linguistic Practices, Discourses, and Identities in a South Korean Political Podcast Naneun Ggomsuda. The Sociolinguistic Journal of Korea 22(2), 111-134. This paper attempts to demonstrate how speakers' identities are shaped, negotiated, and performed through linguistic practices in a South Korean political podcast called, Naneun Ggomsuda. Focusing on the linkage between linguistic practices and identity performances, I employ two meaningful metaphors embedded in Naneun Ggomsuda, ‘resistant’ and ‘theatrical,’ and explore intersections among these metaphors and linguistic practices, discursive features, and speakers' identities. Within the resistant and theatrical fields of discourse, speakers actively apply speaking strategies to achieve their goals, which include their identity making process strongly interconnected to their resistant and theatrical linguistic practices. Two kinds of identities, resistant identity and theatrical identity, are the focus, and these identities are not only shaped and performed through speakers' linguistic interactions, but also collided and negotiated by both speakers and audiences in and out of the talk show. While many previous studies have focused on Naneun Ggomsuda as an ‘alternative media,’ this paper reveals that Naneun Ggomsuda can actually be a fruitful venue for the academic investigation of linguistic practices and identity making processes.

We have generated 383 independent transgenic lines for genetically modified (GM) rice that contained PsGPD (Glyceraldehyde-3-Phosphate Dehydrogenase), ArCspA (Cold Shock Protein), BrTSR15 (Triple Stress Resistance 15) and BrTSR53 (Triple Stress Resistance 53) genes over-expression constructs under the control of the constitutive (CaMV 35S) promoter. TaqMan copy number assay was determined inserted T-DNA copy number. Also flanking sequence tags (FSTs) analysis was isolated from 203 single copy T-DNA lines of transgenic plants and sequence mapped to the rice chromosomes. In analyzing single copy lines, we identified 157 flanking sequence tags (FSTs), among which 58 (36%) were integrated into genic regions and 97 (62%) into intergenic regions. About 27 putative homozygous lines were obtained through multi-generations of planting, resistance screening and TaqMan copy number assay. To investigate the transgene expression patterns, quantitative real-time PCR analysis was performed using total RNAs from leaf tissue of single copy, intergenic region of T-DNA insertion and homozygous T2 plants. The mRNA expression levels of the examined transgenic rice were significantly increased in all of the transgenic plants. In addition, myc-tagged 35S:BrTSR15 and 35S:BrTSR53 transgenic plants were displayed higher levels of transgene protein. These results may be useful for producing of large-scale transgenic plants or T-DNA inserted mutants in rice.

TaqMan copy number assay was determined inserted T-DNA copy number. Also FSTs analysis was isolated from 203 single copy T-DNA lines of transgenic plants and sequence mapped to the rice chromosomes. In analyzing single copy lines, we identified 95 FSTs, among which 37 (38.9%) were integrated into genic regions and 58 (61.1%) into intergenic regions. About 27 homozygous lines were obtained through multi-generations of planting, resistance screening and TaqMan copy number assay. To investigate the transgene expression patterns, quantitative real-time PCR analysis was performed using total RNAs from leaf tissue of single copy, intergenic region of T-DNA insertion and homozygous T2 plants. The mRNA expression levels of the examined transgenic rice were significantly increased in all of the transgenic plants. In addition, myc-tagged 35S::BrTSR15 and 35S::BrTSR53 transgenic plants were displayed higher levels of transgene protein than WT plants. These results may be useful for producing of large-scale transgenic plants or T-DNA inserted mutants in rice.

In plants, the Dof (DNA binding with One Finger) proteins are plant-specific transcription factors with a particular class of zinc-finger DNA-binding domain. The Dof genes have been predicted 30 different Dof genes in the rice Oryza sativa genome by phylogenetic analysis. The mostly Dof proteins contain a conserved region of 50 amino acids with a C2-C2 zinc finger motifs that binds a cis-regulatory element sequence 5’-T/AAAAG-3’. We found that a member of the DOF transcription factor family, Dof1 gene of rice, was expressed to wound from Ds insertion mutant population. Sequencing of the flanking regions of the transposon insertion site indicated that the gene-trap had been inserted near the front of the second exon of OsDof1 gene in chromosome 7. Genomic southern analysis revealed that mutant line contained a single copy of Ds gene trap. The Ds tagged rice mutant line, OsDof1::Ds, wound-inducible GUS expression was identified. To analyze the cis-acting elements, we constructed fusion genes with the OsDof1 promoter fused to the β-glucuronidase (GUS) reporter gene and transformed Arabidopsis and rice plants with these constructs. Wound-induced GUS expression was observed in the leaves of transgenic OsDof1::GUS rice and Arabidospsis plants. These results showed that, OsDof1 protein might be involved in stress responses and growth regulation in plant, might plays a role as a transcription regulator in stress response signal transduction pathways of plant.
