- Аннотация: We report here on the effect of association between wheat plants and bacteria of the genus Azospirillum on the physiology and biochemistry of the associated partners. Lectin studies revealed strain-specific interaction of a wheat lectin with azospirilla. Inoculation of wheat seedlings with different Azospirillum strains and phytohormone (indole-3-acetic acid and abscisic acid) treatments brought about changes in specific lectin activity and in wheat root growth parameters. At concentrations of 0.5 – 2.0 mg/L, wheat lectin was stimulatory to the synthesis of indole-3-acetic acid in Azospirillum cells grown on a nitrogen-free medium under microaerophilic conditions. Changes in the synthesis of hydroxyproline-rich proteins and in the activities of exoglycosidases due to Azospirillum inoculation were also noted. These findings are in support of the views that the effect of Azospirillum on plants (wheat) is largely due to …
