Internalization of fluorescently labeled CPPs, pVEC, transportan and scrambled pVEC, in a range of plant cells was investigated. Cellular uptake of the peptides was found to be tissue dependent. pVEC and transportan were distinctly internalized in triticale mesophyll protoplasts, onion epidermal cells, leaf bases and root tips of seven-day old triticale seedlings but showed negligible florescence in coleoptile and leaf tips as observed under a fluorescence microscope. Further, pVEC and… CONTINUE READING
