The developmental cytology of the elaiosome of
Dicentra formosa (Andr.)Walp. was investigated from the
time of initial differentiation until complete maturation.
Light and transmission electron microscopy studies
showed that the elaiosome becomes differentiated from
epidermal tissue in the prefertilized ovule. At this time
the cells are characterized by their large...
Crown gall infected and healthy Kalanchoe pinnata (Lam.)

tissues were quantitatively measured. The plants were inoculated
with the bacterium, Agrobacterium tumefaciens (Smith and Townsend)
Conn., on one side of...
