The biochemical activity of the protein was tested and its in vivo function was preliminarily analyzed. AtMYB305 contains two imperfect repeats (R2, R3) in its DNA binding domain. Gel mobility shift assay demonstrated that GST-AtMYB305 fusion pro-tein bound specifically to the DNA fragment that included a consensus MYB recognition sequence (TAACTG). Overex-pression of AtMYB305 in the fission yeast caused the forma-tion of elongated cells with one condensed nucleus. Semi-quantitative RT-PCR analysis revealed that AtMYB305 was expressed specifically in the roots of Arabidopsis.展开更多
