Thus, the role of lipoxygenase and polyamines was studied in the wilt pathogen infected and non infected tissues of resistant and susceptible genotypes of castor at 0days after infection (DAI), 5 DAI and 10 DAI (30days after sowing). The lipoxygenase (LOX) and polyamine oxidase (PAO) activities were higher in the incompatible interaction at all the stages of analysis. The constitutive level of malondyaldehyde (MDA) content, a product of lipid peroxidation was higher in susceptible genotypes (VP-1 and VI-9), while induced level was higher in resistant genotypes (48-1 and SKP-84) at 5 DAI and 10 DAI . Polyamine profiling using HPTLC showed higher spermidine and spermine content in resistant genotypes at 10 DAI. Furthermore, spermidine was detected only in the roots of resistant genotypes at 10 DAI. These results suggest the role of high titers of polyamines, LOX and PAO in disease resistance possibly through HR induction. Prof. H.S.
