text: Phloem, yo, specialized plant tissue flowin'
  Superhighway for macromolecular exchanges, knowin'
  Organs and tissues connectin', plants showin'
  Mobile macromolecules, signals growin'
  
  RNAs in the mix, non-cell-autonomous pathway proteins assist
  Movin' through plasmodesmata, symplasmic passage persist
  Phloem stream, where they don't resist
  Graftin' experiments, next-gen sequencin' assist
  
  Arabidopsis mobile mRNAs, 11.4% showin' TLS motif
  tRNA-like structure, discovery's a belief
  Add it at the 5' end, cell-autonomous RNAs get relief
  GUS transcript, movin' through graftin' junction, bringin' belief
  
  Accumulated data, TLS motif's role in RNA mobility
  PLaMoM database, plant biologists' utility
  Web server built, predictions with agility
  Plant scientists investigatin' RNA mobility, real facility
