Evaluation of biological control strategies against a range of plant pathogens
Year: 2017
Type: dissertation
Abstract: The present investigation entitled “Evaluation of Biological Control Strategies against a Range of Plant Pathogens” was undertaken during the summer (April) of 2015 and stretched for one year. The experiments were primarily focused on observing the biocontrol potential of Paenibacillus alvei (strain K165 ) against Cucumber mosaic virus , Potato virus Y and Tomato spotted wilt virus in tomato ( Solanum lycopersicum ) plants; and the use of natural zeolite (from Kimolos island) in suppressing the soil bor ne plant pathogens, namely, Rhizoctonia solani , Pythium ultimum and Scleortinia sclerotiorum in lettuce ( Lactuca sativa ) plants. The observations made were based on severity of the phenotypic symptoms monitored in lettuce and tomato plants. The examination of tomato plants for the virus presence was done using enzyme linked immune sorbent assay (ELISA) test. There was no s ignificant resistance offered by biocontrol bacterium K165 against the different viruses tested. Although the plants infected with virus did not show extreme visual viral symptoms but still the ELISA test confirmed the presence of virus. Zeolite was able t o confer partial resistance in the lettuce plants against Sclerotinia sclerotiorum . Different mutants ( mpk3 , mpk6, bam ) of Arabidopsis thaliana were also tested for their resistance against Cucumber mosaic virus . BAM mutants showed partial resistance and l ess viral load when tested through ELISA.
