Description
  • Intergenová oblast psbA-trnH v chloroplastovém genomu krytosemenných rostlin je velmi variabilní a hojně využívaná při studiu populací. Byla navržena k použití pro „barcoding“, tedy k určování druhů podle DNA sekvence. Tato oblast obsahuje psbA 3’UTR přepisovaný úsek. Srovnali jsme sekvenci a sekundární strukturu RNA v této oblasti u krytosemenných rostlin a nalezli konzervované motivy odpovídající stonkům vlásenek dvouřetězcové RNA a konsensus sekvenci TTAGTGTATA, která nevykazovala výraznou sekundární strukturu. Srovnání chloroplastových UTR pomůže pomoci najít evolučně konzervované elementy a pochopit evoluci nekódujících oblastí chloroplastov0ho genomu. (cs)
  • The psbA-trnH intergenic region is among the most variable regions in the angiosperm chloroplast genome. It is a popular tool for plant population genetics and species level phylogenetics and has been proposed as suitable for DNA barcoding studies. This region contains two parts differing in their evolutionary conservation: 1) the psbA 3’UTR (untranslated region) and 2) the psbA-trnH intergenic non-transcribed spacer. We compared the sequence and RNA secondary structure of the psbA 3' UTR across angiosperms and found consensus motifs corresponding to the stem portions of the RNA stem-loop structures and a consensus TTAGTGTATA box. The psbA-trnH spacer exhibited patterns explicable by the independent evolution of large inversions in the psbA 3’UTR and mutational hot spots in the remaining portion of the psbA-trnH spacer. We conclude that a comparison of chloroplast UTRs across a angiosperms offer clues to the identity of putative regulatory elements and information about selective constraints impos...
