Abstract

In our study, cross section of the healthy and Tungro infected leaf sample of rice exhibited wide differences among the cells. The area of vascular bundles was reduced in the Tungro infected rice samples and lower epidermis cells got damaged wherein the area was large in the healthy rice leaf. In case of healthy leaves of rice, the cells were normal in size with properly distributed intercellular spaces and evenly present bundle sheath cells. The xylem and phloem tissues showed no damage in healthy sample. Bundle sheath cells remained undisturbed above the phloem tissues. In the infected rice leaf section, due to the invasion by both the RTBV and RTSV viruses, bundle sheath cells and phloem got distorted.
