摘要:
Expression vectors and expression cassettes containing a tissue specific 5′ transcription regulatory element, optionally linked to a translation regulatory element, optionally linked to an intron transcription regulatory element, operably linked to a heterologous polynucleotide encoding a protein or RNA of interest are described. The 5′ transcription regulatory elements control expression in root tissue cells, phloem tissue cells, or fruit and/or abscission zone tissue cells. These sequences are obtained from citrus plants. Methods of use of these expression vectors and expression cassettes are described, as well as genetically altered plants and parts thereof that contain these expression vectors and/or cassettes.
