ABSTRACT

Abstract Objective Chickpea phyllody caused by phytoplasma occurs worldwide. However, the alterations in the host physiology and its associated biochemical components induced by the infection with phytoplasma in chickpea plant remain unknown. Methods In present study, the changes in phenolic compounds, protein contents, phenylalanine ammonia-lyase (PAL), peroxidase (POX), catalase (CAT), polyphenol oxidase (PPO) and chlorophyll contents were analyzed in phytoplasma-symptomatic and non-symptomatic plants of two Kabuli and three Desi type chickpea genotypes. Results Total phenols were statistically at par in symptomatic plants of both Kabuli and one Desi (Bittle-98) genotype but significantly increased in genotype Aug-424 and decreased in C-727. Protein contents were significantly decreased in symptomatic plants of all genotypes except CM-2008. PAL activity was significantly increased in all Kabuli but decreased in all the Desi genotypes. POX activity was significantly increased in Noor-2009 and Aug-424 but decreased in CM-2008 and Bittle-98. PPO activity was increased in two genotypes but decreased in others. CAT activity and chlorophyll contents were decreased in all genotypes. Conclusion The present finding indicates that phytoplasma causes non-specific, general stress response by interfering with host metabolism and photosynthesis. The study also provided significant insights for better understanding the mechanisms of chickpea plant response to phytoplasma.
