Retrograde response by reactive oxygen/nitrogen species in plants involving different cellular organelles

Abstract

AbstractDuring oxidative and nitrosative stress conditions cellular organelles convey information to the nucleus to express specific sets of genes to withstand the stress condition and to reorganize their growth and developmental pattern. This organelle to nucleus communication is termed retrograde signaling. In the plant system chloroplast and peroxisomes are mainly involved with little involvement of mitochondria and other organelles in oxidative stress-mediated retrograde signaling. In this review, we will discuss retrograde signaling in plant systems with factors that regulate this signaling cascade.
