چکیده انگلیسی
Plants encode various proteins which are closely related to bacterial maturases. The organellar genomes contain one maturase each, named MatK in chloroplasts and MatR in mitochondria. In addition, several maturase genes have been found in the nucleus as well, which are acting on mitochondrial pre-RNAs. All plant maturases show sequence deviation from their progenitor bacterial maturases, and interestingly are all acting on multiple organellar group II intron targets. Moreover, they seem to function in the splicing of group II introns together with a number of additional nuclear-encoded splicing factors, possibly acting as an organellar proto-spliceosome. Together, this makes them interesting models for the early evolution of nuclear spliceosomal splicing. In this review, we summarize recent advances in our understanding of the role of plant maturases and their accessory factors in plants. This article is part of a Special Issue entitled: Chloroplast Biogenesis.
