Light-and phytohormone-induced variations in the level and modified nucleotide content of plastid tRNAs

Abstract

Understanding the regulatory role of tRNA in organelle protein synthesis and the mechanisms by which light and phytohormones regulate the levels of individual functional tRNA species are major challenges. This review focuses on our current knowledge of light-and phytohormone-induced changes in the levels of plastid tRNA species and the contents of modified nucleotides in plant seedlings. The possible regulatory mechanisms by which light and phytohormones regulate the relative amounts of functional tRNA species in plastids are discussed
