Variations in Protein Content Due to Proteolytic Enzyme Activities and Their Influence on Susceptor Resistant Response in Maize — Erwinia carotovora var. chrysanthemi Host-Pathogen System

摘要: Summary The susceptibility of maize varieties ‘Vijay’, ‘Popcorn’, and ‘Swan’ towards the three isolates ‘Columbia’, ‘Hawaii’, ‘Wisconsin’ Erwinia carotovora var. chrysanthemi was due to increase or decline protein content, enhanced proteolytic enzyme activities, diminution total amino acid output in stalk- leaf-tissues middle- old-age-group plants. interaction activities at summit 16 d after infection all age groups heightened activity with concurrent release components as nutrients sustained susceptibility. In younger tissues these cultivars such a response maintained through restricted acids, specially those which were inhibitory 3 pathogen. This apparent especially variety ‘G.S.2’, where accumulated infected simulate lessening excreted compounds. Here incorporated itself free acids acted inhibitors. resistance young ‘Pant-7421’ mature ‘Pool’ engineered content nutritionally utilizable acids. resistant ‘Pant’ middle aged tissue conducted protein, accompanied vigorous high level output, repressor bacterium during host-pathogen interplay.
