Fungal adhesion to the host surface mediated by initial binding and recognition is an important event which subsequently leads to infection and pathogenesis to host plants. Lectins bind well to the carbohydrates present on plant cell surfaces. Thus, lectins in phytopathogenic fungi may play a role together with cell-wall degrading enzymes in the infection process. The degree of infection of jute seedlings by a 60-day-old mycelial suspension of M. phaseolina increased to the same level as that of a young (7-day-old) mycelial suspension with the addition of M. phaseolina lectin (35 μg mL-1) to the incubation medium. The intensity of infection of the jute seedlings by the 60-day-old mycelia was unchanged even after the addition of L-asparagine (35 μg mL-1) to the medium suggesting that increased fungal infectivity was not a result of the use of M. phaseolina lectin as a nutrient source. Agglutinin production in M. phaseolina infected jute seedlings was 87 ng per seedling on the fifth day of infection as quantitated by ELISA. The amount of M. phaseolina lectin accumulated in the culture media increased if host (jute seedlings) cell wall or its components, e.g., such as pectin, cellulose, xylan was added to the mycelium. So, this lectin is suggested to play a role in the recognition and infection process of host plants.]]>Bhowal, J., S. Ghosh, B.P. Chatterjee and A.K.
