| Popis: | Electron and light microscopy show that the foliar tissues of beans affected by the Bean Rugose Mosaic Virus (BRMV) disease undergo strong histologic and cytologic changes. The leaf blade is rugose and irregular, the stomata are malformed, the cuticle is striated, the mesophyll is packed and the intercellular spaces are missing. There are few, small and clear-colored chloroplasts; occasionally, they are degenerated. Sclerotic cells filled with phenolic substances are frequently found in severely affected areas. There is a general lack of correlation between growth of the organ and development of the tissues. Hypertrophy, hyperplasia, hypoplasia and eventual necrosis are the outstanding characteristics of this viral infection. |
