Molecular and biochemical characterization of cotton epicuticular wax in defense against cotton leaf curl disease

ABSTRACT

Background: Gossypium arboreumis resistant to Cotton leaf curl Burewala virus and its cognate Cotton leaf curl Multan beta satellite [CLCuBuV and CLCuMB]. However, the G. arboreum wax deficient mutant [GaWM3] is susceptible to CLCuV. Therefore, epicuticular wax was characterized both quantitatively and qualitatively for its role as physical barrier against whitefly mediated viral transmission and co-related with the titer of each viral component [DNA-A, alphasatellite and betasatellite] in plants
