Lipoic acid and autophagy: new insights into stem cell aging.

abstract：:Chloroplast genes of higher plants are transcribed by two types of RNA polymerase that are encoded by nuclear (NEP (nuclear-encoded plastid RNA polymerase)) or plastid (PEP (plastid-encoded plastid RNA polymerase)) genomes. NEP is largely responsible for the transcription of housekeeping genes during early chloroplast...
