Comparative analysis of non-autonomous effects of tasiRNAs and miRNAs in Arabidopsis thaliana.

abstract：:Expression of the wild-type p53 tumor suppressor gene has been found to play an important role in the regulation of cellular proliferation and differentiation. In addition, in many transformed cells and primary tumors, the gene has undergone allelic deletions and mutant forms of the p53 gene are expressed at elevated ...
