The anatomical changes in stem, petiole and different leaves of urdbean leaf crinkle infected plant parts were highly conspicuous and were increase in number of layers and size of parenchyma cells and epidermal cells. The transverse section of infected stem of urdbean showed well developed cortex layer which was three times thicker than that of healthy leaf. The epidermal cells of infected tissue were significantly bigger than in healthy leaf. The number of vascular bundles increased in infected stem. The number of rows of xylem vessels and number of vessels per row were almost double in infected stem. The diameter of xylem vessels (metaxylem and protoxylem) increased significantly over healthy vessels. There was significant increase in number of layers of parenchyma cells and cambial cells and diameter of phloem parenchyma in diseased plant compared to healthy stem
