    摘要: In this invention, a method is described that allows for the efficient creation and identification of validated biological materials that greatly enhance the ability to perform polysome-mediated RNA profiling, such as constitutive, cell type-, tissue type-, or condition-enhanced RNA profiling. The method relies on the use of a tri-partite plant binary expression vector comprised of the following components: a) a DNA promoter element that drives expression of a sequence specific transcription activator protein such as a LexA:Gal4 fusion protein in a unique desired pattern, b) a DNA promoter element comprising a target site for the transcriptional activator protein, such as opLexA, fused to a nucleotide encoding an epitope tagged ribosomal component protein and c) a DNA promoter element comprising a target site for the transcriptional activator protein, such as opLexA, fused to a nucleotide encoding an in vivo reporter protein. By visualization of the co-regulated reporter, this method allows for in planta confirmation that the promoter element is driving expression, such as constitutive, cell type-, tissue type-, or condition-enhanced expression, of the tagged ribosomal protein in the desired cell or tissue types.
