LEXINGTON, KY - It’s common knowledge that plants grow up from the
ground, supported by a root system, but until now scientists were unable
to understand how that process starts during fertilization at a
cellular level. An international team of scientists that includes a
University of Kentucky researcher has visualized how the fertilized egg
cell divides unequally after fertilization.
From this unequal
cell division, one cell works toward developing the top part of the
plant including stem, leaves and flowers while the other works on root
structure.
