Under congenial environmental conditions, spores (conidia) germinate readily in the presence of moisture by producing a germ tube, which penetrates the hosts directly or through stomata. Further, the process of infectio

During reproduction, all individuals are expected to be different from each other and from their parents in a number of characteristics, although they retain most similarities with them and belong to the same species (Agrios 2005).

Changes in the internal organelles of hypha, conidium and conidiophore have been observed. Conidiophores have a similar structure to mature hyphae, except that after spore production, they have pore in the tip and an annulus. Ther
