D. Jackson et S. Hake, MORPHOGENESIS ON THE MOVE - CELL-TO-CELL TRAFFICKING OF PLANT REGULATORY PROTEINS, Current opinion in genetics & development, 7(4), 1997, pp. 495-500
It has been shown recently that some plant transcription factors that
regulate cell fate during development can traffic through plasmodesmat
a - the intercellular channels that connect plant cells. This phenomen
on helps explain the non-autonomous effects of many developmental muta
tions in plants and defines a novel mechanism by which cells signal to
each other during development.
