Abstract: A virus disease showing symptoms like mottling followed by leaf deformities was characterized from Chilli. The infected plants show very important symptoms in the cells which are specific host virus combination. A relationship between nucleus and its cytoplasm for its energy supply. Cytoplasm also depends upon nucleus for its replacement. The power nature of the nucleus envelope permits the ready passage of materials in either directions. The Nucleus / Cytoplasmic ratio of disease cells (0.187) was more than healthy cells (0.105). The Mitotic Index (MI) in the meristmetic cells of diseased cells (5.85) was quite low in comparison to the healthy cells (20.78) of Capsicum annuum L.
