Abstract:
Phytoplasma has drastically affected economically important crops like brassica napus. Physiological changes and its related biochemical compounds produced upon phytoplasma infection in brassica napus plants remain unknown. The aim of this study was to find out the morphological and physico-chemical response of brassica napus plants against phytoplasma attack. In this study, phytoplasma was transmitted to brassica plants through grafting and insect vector, Orosious orientalis. In the present study change in morphology and physico-chemical attributes like chlorophyll a, chlorophyll b and total chlorophyll contents, the changes in total phenolic contents, total soluble proteins, H2O2 contents, peroxidase, (POD) and catalase (CAT) were analyzed in plants after phytoplasma attack. The data revealed that the phytoplasma attack results in small leaf size and stunted growth totally changed floral morphology and photosynthetic pigments like like chlorophyll a, b and total chlorophyll contents were reduced in brassica plants. The catalase, phenolics, amino acid, free protein and H2O2 contents were increased showing more susceptibility of brassica plants towards phytoplasma attack. More production of catalase and H2O2 contents and reduction of POD contents are important strategies to analyze severity of phytoplasma attack on brassica plants.
