Genetic mosaics and cell lineage analysis in plants

Trends Genet. 1989 Aug;5(8):273-7. doi: 10.1016/0168-9525(89)90101-7.


The use of genetic mosaics for cell lineage analysis has revealed several important features of plant development. All multicellular organs in higher plants are polyclonal in origin. Although primordial cell lineages have fairly regular fates, the fate of any given cell within these lineages cannot be accurately predicted. Cell fate appears to be determined by the final location of a cell rather than by its history.
