Abstract:

The metabolic changes that took place during host-pathogen interaction have been poorly investigated. Although photosynthesis disturbance and carbon metabolism re-programming have been studied yet, there is scary of data on plant amino acids after induction of resistance. Here we investigated the amino acid contents in induced and un-inoculated and invaded region after induction of resistance. The quantities of methionine, iso-leucine, leucine, tyrosine and phenylalanine contents in three (Pb-91, C-44 and Bittle-98) chickpea cultivars increased after induction and stress of A. rabiei and comparatively higher than induced unstressed plants. The increase was more evident in case of Bion treatment as compared to all other treatments with SA and KOH. Similar trend was shown by plant extracts where in neem extract induced higher amino acid contents. The cultivar C-44 responds eficiently as compared with other two cultivars. The results of the current study showed that amino acids play significant role in resistance and susceptibility of chickpea cultivars against A. rabiei.
