Sažetak
Aproximately 4200 nucleoids of the 16S/23S DNA spacer and the 5 region flanking the rrn operon of the plastid chromosomes representing the five basic, physiologically related Euoenothera plastoms were sequenced and compared. The sequencec that harbor the putative replications origins are almost identical except for a 785-bp intercistronic segment between the genes for the 16S rRNA and trnl. Differences are mainly caused by insertions/deletions and duplications ; the predicted potential for formation of quite extensivesecondary structure differs among the plastomes. Unexpected intraplastomes variation has also been noted. Furthermore, the sequence-based and published genetically deduced plastome pedigrees differ significantly.
