Abstract excerpt
Phloem-mobile endogenous RNA is trafficked selectively into the shoot apex. In contrast, most viruses and long-distance post-transcriptional gene silencing (PTGS) signals are excluded from the shoot apex. These observations suggest the operation of an underlying regulatory mechanism. To examine this possibility, a potexvirus movement protein, known to modify cell-to-cell trafficking and PTGS, was expressed...
