Histological changes at the seedling growth (Z12) and stem elongation (Z31) stages after Tilletia controversa infection

Abstract Tilletia controversa Kühn is the causal agent of dwarf bunt disease in wheat. Understanding infection T. practical and scientific importance for management. Here, we used scanning electron microscopy to characterize histological changes at seedling (Z12) stem elongation stages (Z31) resistant susceptible wheat cultivars after infection. At stage (Z12), structure mesophyll cells slightly deformed pathogen infection, but this deformation was greater cultivar than cultivar. (Z31), structures root parenchyma epidermal were more both cultivars.
