Abstract:

Bacterial wilt caused by the soil-borne bacterium R. solanacearum race 4 is a lethal disease of several vegetables and spices in the family Solanaceae and Zingiberaceae respectively. In order to understand the phenotypic response of six A. thaliana ecotypes [Landsberg Erecta (Ler) Columbia-0 (Col-0), ABH1, Hc160, Sc1 and SIC] to R. solanacearum isolate, CaRs-Mep, different dilution of bacterial suspension were inoculated on roots of plants. The bacterium typically wilted the plantlets in a density dependent manner where the yellowing and witling was observed within 7 days and 14 days at 10 and 1 OD unit respectively. All ecotypes were highly susceptible to race 4 strain of R. solanacearum, except ecotype Ler, where no yellowing and changes in root and shoot length was observed. Ler ecotype showed complete resistant phenotype and hence can be used in resistance programme against the R. solanacearum Race 4.
