The Effect of Free Radical Enhancers and Scavengers on Accumulation of Early Light-Inducible Protein during Light Stress

Abstract

Involvem ent o f active oxygen species in the accum ulation o f early light-inducible protein (ELIP) in m ature pea plants was investigated under light stress conditions. Here we provide evidence that hydroxyl radicals and singlet oxygen interfere with E L IP expression a t bo th , transcrip tional and posttranslational levels. A ddition o f free radical scavengers can alleviate the detrim ental action o f the radicals alm ost com pletely a t the level o f transcrip tion but only a partial protection was observed at the level o f proteins. The d a ta suggest th a t the dam age o f E LIP occurs during its insertion into thylakoid m em branes close to the free radical sources.
