Overexpression of NtmybA2 in tobacco BY-2 cells

ABSTRACT: Promoters of many G2/M phase-specific genes in plants contain mitosis-specific activator (MSA) elements, which act as G2/M phase-specific enhancers and bind with R1R2R3-Myb transcription factors. A least three R1R2R3-Myb proteins are expressed in tobacco (Nicotiana tabacum). To examine the genome-wide effects of NtmybA2 overexpression, we constructed transgenic tobacco BY-2 cell lines overexpressing full-length NtmybA2 protein. In addition, we generated transgenic BY-2 cell lines that overexpress truncated hyperactive form of NtmybA2 (NtmybA2∆C) lacking its C-terminal region which negatively regulates its own activity for transcriptional activation. We used a custom-made 16K cDNA microarray for comparative transcriptome analysis of these transgenic tobacco BY-2 cell lines. As control sam
