Abstract:

As a response of host-pathogen interaction, the induction of systemic resistance (ISR) was studied in cassava upon challenge inoculation with cassava mosaic viruses (ICMV and SLCMV). Due to the viral infection, the reduced amount of chlorophyll a, chlorophyll b and total chlorophyll was recorded in virus infected cassava seedlings compared to control (meristem derived healthy plants). The accumulation of total phenol, total sugars and total soluble proteins were found to be reduced in virus infected seedlings than control. Moreover, the activity of defense enzymes viz., peroxidase (PO), polyphenol oxidase (PPO), phenylalanine ammonia lyase (PAL) and catalase was found to be increased in infected cassava seedlings compared to control. In addition an increased expression of specific isoforms of PO (PO2 and PO3) and PPO (PPO2 and PPO3) were observed in native PAGE analysis with response to challenge inoculation of pathogen due to induced systemic resistance (ISR) induction.


Keywords: Cassava, Chlorophyll, Phenol, Sugars, Soluble proteins, Defense enzymes.
