Protoplasma Aims and scope Submit manuscript

Summary

The inception and developmental phases of sunflower (Helianthus annuus) crown gall tumor growth induced byAgrobacterium tumefaciens were studied submicroscopically. Bacteria were found only in the inception phase. Chloroplasts from tumor cells of both phases showed several kinds of structural variation. Other cytoplasmic organelles remained more or less normal.
