Abstract
Partially purified non-specific Lipid Transfer Proteins (ns-LTPs) of plant source were treated to pearl millet seeds at different concentrations for six hours. Among the tested, rice ns-LTP (100 μg/ml) showed a maximum seed germination of 94% and 1385 seedling vigour followed by maize and wheat. The treated seeds also enhanced growth parameters when compared to control plants. The maximum downy mildew disease protection of 56% was offered by rice ns-LTP (100 μg/ml) followed by maize and wheat which offered 52% and 47% protection, respectively. The ns-LTPs of maize and rice required minimum of three days after challenge inoculation to build up maximum resistance to downy mildew. The present investigation suggests that the ns-LTPs from plant source can be used as inducers in managing pearl millet downy mildew disease and also for plant growth promotion.
