The Karnal bunt disease is a very important disease of wheat which is stable food for human beings caused by Tilletia indica (T. indica). This disease profoundly affects wheat yield attributes since it causes the bed smell due to the presence of trimethyl amines. Therefore it is directly related to the wheat trade and leads to key interest among the researchers to understand more about the pathogen T. indica. However, this pathogen showed high variation in morphological, biochemical, and developmental forms. Observed results suggested that the variability among the monopodial culture was mostly because of genetic factors. Moreover, variability is also because of internal factors apart from external environmental factors. Therefore here it is very obvious to understand more about some internal factors of the host so-called host factors which are much pronounced in monosporidial strains.

Host factors are heat labile and have a profound effect on the pathogen because of nutritional and hormonal effects. How the host factors responsible for pathogenesis is not elucidated till now. In the present study, we could observe that the host factors play an important role in the total amount of protein in a time-kinetic manner among, the different monopodial strains of Tilletia indica. We also observed that host factors treated strain showed more biomass production apart from an increase in the radial diameter of monopodial culture. This new observation will open up new horizons to know more about the pathogenesis that leads to the quarantine of Karnal bunt disease. Moreover, it will also provide morphological markers specific to the strain of Tilletia indica this could be useful for investigating the levels of pathogenesis apart from protein biochemistry and finally management of Karnal bunt disease.
